MODELIRANJE SIMETRIJE I ANTIMETRIJE
MODELING OF SYMMETRY AND ANTIMETRY

[Mon Dec 15 10:02:48 2003]
Kod formulacije proračunskih modela iz konačnih elemenata ukoliko postoji simetrija sustava i simetrija opterećenja ili simetrija sustava i antimetrija opterećenja, nije potrebno proračunavati cijeli sustav, već samo jednu polovinu sustava, a drugu polovinu sustava može se onda zamijeniti pogodnim rubnim uvjetima koji zamjenjuju simetriju ili antimetriju sustava.
In the formulation of calculation models from finite elements, if there is symmetry of system and symmetry of the load, or symmetry of the system and antimetry of the load, it is not necessary to calculate the whole system, but only one half of it, and the other half can be replaced with appropriate boundary conditions, which replace symmetry or antimetry of the system.

[Mon Dec 15 10:04:27 2003]
Prikazuje se nekoliko primjera takvog modeliranja.
Several examples of such modeling are shown.

[Mon Dec 15 10:05:10 2003]
Najjednostavniji je slučaj jednostavna greda, koja je a) simetrično opterećena (npr.
The simplest case is a simple beam, which is a) symmetrically loaded (e.g.

[Mon Dec 15 10:05:10 2003]
kontinuiranim jednolikim opterećenjem), i b) antimetrično opterećena
with continuous uniform load), and b) antimetrically loaded

[Mon Dec 15 10:07:43 2003]

According to MS STRUDL or ICES STRUDL for bearing nodes it is introduced

[Mon Dec 15 10:33:30 2003]
U COSMOS/M programu postoje nalozi za modeliranje rubnih uvjeta stanja simetrije i stanja antimetrije:
In COSMOS/M program, there are commands for modeling boundary conditions of symmetry and antisymmetry states:

[Mon Dec 15 10:35:17 2003]
SYMBC za generiranje simetričnih rubnih uvjeta u ravnini simetrije, i nalog ASYMBC za generiranje asimetričnih rubnih uvjeta u ravnini asimetrije.
SYMBC for generating symmetrical boundary conditions in the plane of symmetry, and ASYMBC command for generating asymmetric boundary conditions in the plane of asymmetry.

[Mon Dec 15 10:35:17 2003]
Pri tom se simetrija i antisimetrija rubnih uvjeta može izraziti u Cartezijevom, globalnom cilindričnom, globalnom sfernom i prethodno definiranom lokalnom koordinatnom sustavu (vidjeti priručnike)
Symmetry and antisymmetry of boundary conditions can be expressed in Cartesian, global cylindrical, global spheric and earlier defined local coordinate system (see manuals)

[Mon Dec 15 10:37:41 2003]
U prethodnim primjerima to se može onda izraziti kao
In previous examples, it can be expressed as

[Mon Dec 15 10:45:13 2003]
Vrijednost 2.5 u nalogu je udaljenost ravnine simetrije od ishodišta koordinatnog sustava, dok je vrijednost 0,01 mjera tolerancije odredbe ravnine u kojoj su locirani čvorovi koji definiraju ravninu simetrije (ili antisimetrije).
5 in the command is the distance of the plane of symmetry from the origin of coordinate system, while the value 0,01 is the measure of tolerance of the order of plane in which the nodes are located which define the plane of symmetry (or antisymmetry).

[Mon Dec 15 10:45:13 2003]
U ovom slučaju je taj podatak irelevantan
In this case, this information is irrelevant

[Mon Dec 15 10:48:46 2003]
Modeliranje uvjeta antimetrije korištenjem naloga ASYMBC

[Mon Dec 15 10:53:40 2003]
Naročito treba biti pažljiv kod korištenja simetrije i antimetrije pri proračunima modova titranja konstrukcija.
It is necessary to be particularly careful in using symmetry and antisymmetry in calculations of modes of structure vibrations.

[Mon Dec 15 10:53:40 2003]
Rubni uvjeti simetrije i antisimetrije moraju se podudarati s elastičnom linijama pojedinih modova titranja!
Boundary conditions of symmetry and antisymmetry must correspond with elastic lines of some modes of vibration!

[Mon Dec 15 10:58:30 2003]
Na primjer, ako se razmatra po obodu upeta kružna ploča može se razmatrati 1/4 ploče samo za prvi prirodni mod titranja ploče
For example, if a cycle plate fixed along the perimeter is analyzed, only 1/4 of the plate can be analyzed for the first natural mode of plate vibration

[Mon Dec 15 11:04:13 2003]
kružna ploča oslonjena po obodu ploče.

[Mon Dec 15 11:34:26 2003]
za jednoliko i simetrično opterećenje ploče kod statičke analize i kod proračuna 1 moda titranja može se razmatrati 1/4 ploče uz odgovarajuće rubne uvjete.
for uniformly and symmetrically loaded plates, in static analysis and in calculation of the 1st mode of vibration, only 1/4 of the plate can be analyzed with appropriate boundary conditions.

[Mon Dec 15 11:34:26 2003]
Za proračun ostalih modova titranja mora se razmatrati cijela ploča
For calculation of other modes of vibration, the entire plate must be analyzed

[Mon Dec 15 11:39:42 2003]
Međutim, za proračun drugog moda titranja NE MOŽE se koristiti ovaj prikazani model
However, for the calculation of the second mode of vibration, the presented model CANNOT be used

[Mon Dec 15 11:43:10 2003]
Također se prikazuje jedan primjer modeliranja ploče gdje se razmatra samo 1/4 ploče za simetrično opterećenje (u prethodno prikazanim primjerima modeliranja prikazan je i model svoda kojeg se modeliralo s 1/4 modela cijelog svoda)
An example of plate modeling is also shown, where only 1/4 of the plates for symmetrical load is analyzed (in previously shown examples of modeling, a model of a vault which was modeled with 1/4 of the model of the entire vault was shown)

Uz modeliranje pravokutne jednoliko opterećene ploče, upete po svim rubovima
With modeling of a rectangular uniformly loaded plate, fixed along all edges

[Mon Dec 15 11:46:45 2003]
Treba razmotriti samo 1/4 ploče, dakle sustav prikazan na slici 32.7
Only 1/4 of the plate should be analyzed, i.e. the system presented on Figure 32.7

[Mon Dec 15 11:52:42 2003]
Zbog uvjeta geometrijske simetrije oslonjene pravokutne ploče i zbog simetrično opterećenja ploče može se u statičkoj i dinamičkoj analizi 1 moda titranja razmatrati samo 1/4 ploče, koristeći odgovarajuće uvjete oslanjanja (simetrije).
Because of the conditions of geometric symmetry of a supported rectangular plate, and because of symmetrical load of the plate, in static and dynamic analysis of the 1st mode of vibration only 1/4 of the plate can be analyzed, using the appropriate support conditions (symmetry conditions).

[Mon Dec 15 11:53:49 2003]
Kod analize ostalih viših modova titranja treba pomno razmotriti uvjete oslanjanja pri razmatranju takvog modela.
In the analysis of other higher modes of vibration, the support conditions should be carefully considered, when analyzing such a model.

[Mon Dec 15 11:54:36 2003]
Najbolje i najsigurnije rješenje je razmotriti modeliranje cijele ploče uz odgovarajuće (zadane) uvjete oslanjanja.
The best and the safest solution is to analyze modelling of the entire plate with appropriate (given) support conditions.

[Mon Dec 15 11:54:36 2003]
Današnji programi rješavaju vrlo velike FEA probleme vrlo brzo
Present-day programs can very quickly solve great FEA problems

[Mon Dec 15 11:58:03 2003]
Osim toga, za sve čvorove mora biti spriječena rotacija oko Z osi, dakle ROTZ=0.
Aside from this, for all nodes, the rotation around Z axis must be prevented, i.e. ROTZ=0.

[Mon Dec 15 11:58:03 2003]
Ovu se rotaciju može spriječiti i nalogom RUN_CHECK i DATA_CHECK
This rotation can be prevented with the command RUN_CHECK and DATA_CHECK

[Mon Dec 15 12:02:03 2003]
Ponekad i kod statičkih analiza može doći do iznenađenja pri nepažljivom korištenju naloga za simulaciju rubnih uvjeta za simetriju ili antisimetriju.
Even in static analyses, there can sometimes be surprises in a careless use of the command for the simulation of boundary conditions for symmetry or antisymmetry.

[Mon Dec 15 12:02:03 2003]
Pokazat će se to na jednom primjeru pneumatske grede (cijevi s unutrašnjim tlakom p i vanjskim opterećenjem P)
This will be shown on one example of a pneumatic beam (pipes with internal pressure p and exterior load P)

The use of symmetry in calculation of the FE model of a pneumatic beam (pipe) modelled from SHELL4L layered FE shells.

[Mon Dec 15 12:05:55 2003]
Ukoliko smo nesigurni u formulaciji rubnih uvjeta simetrije, najjednostavnije je analizirati cijeli FE model pneumatske grede.
If we are uncertain in the formulation of boundary conditions of symmetry, the simplest way is to analyze the entire FE model of the pneumatic beam.

Aksonometrijski prikaz slobodnog ruba (prsten) prikazuje se na slici 26.10
Axonometric representation of a free edge (ring) is shown on Figure 26.10

[Mon Dec 15 12:10:01 2003]
U slučaju da se ne uvedu ovi rubni uvjeti (ROTX=0) doći će od tordiranja cijevi kojeg, naravno, u stvarnosti nema.
If these boundary conditions (ROTX=0) are not introduced, there will come to torsion of the pipe which, of course, does not occur in reality.

[Mon Dec 15 12:10:01 2003]
Stoga je bolje za neiskusne korisnike ne koristiti rubne uvjete simetrije ili antimetrije, jer može doći do modeliranja pogrešnog proračunskog modela
Therefore, the inexperienced users should not use boundary conditions of symmetry or antisymmetry, because otherwise the wrong calcuation model could be modelled

[Mon Dec 15 12:11:32 2003]
Svi čvorovi na liniji (ravnini) simetrije imaju sljedeće rubne uvjete
All nodes on the line (plane) of symmetry have the following boundary conditions

[Mon Dec 15 12:17:59 2003]
Svi čvorovi na tom rubu imaju iste uvjete (i međusobno su vezani pločom, koja u modelu nije prikazana).
All nodes on that edge have the same conditions (and they are mutually connected with the plate, which is not shown in the model).

[Mon Dec 15 12:41:07 2003]
To se može učiniti uvođenjem elastičnog zamjenjujućeg oslanjanja navođenjem koeficijenata KFY (ukoliko je uzgon u smjeru osi Y), odnosno uvođenjem adekvatnog zamjenjujućeg štapa:

If FEA programs M-STRUDL, WinSTRUDL or ROBOT V6 are used for the quasi-dynamic analysis of structures loaded with vehicles, first we select the schemes of vehicles which will move across a certain path on the bridge, and then we summon the generator of moving loads (Figure 34.2)

define directions of the torsional vector of the defined moving load around local coordinate axes of members.

Ukoliko se definira MOMENT, onda se torzioni pokretno opterećenje definira kao torziono djelujuće na definirane štapove.
If MOMENT is defined, then the torsional moving load is defined as torsionally active in relation to defined members.

[Wed Dec 17 10:45:21 2003]
Treba osigurati da su pri tom lokalne X osi definiranih elemenata istosmjerno definirane.
It should be ensured that local X axes of defined elements are codirectionally defined.

[Wed Dec 17 10:47:46 2003]
Ukoliko podnalog MOMENT nije upisan, M-STRUDL predmnijeva da su opterećenja pokretnim silama definirana u GLOBALNOM koordinatnom sustavu.
If the subcommand MOMENT is not entered, M-STRUDL presumes that loads of moving forces are defined in GLOBAL coordinate system.

[Wed Dec 17 10:48:29 2003]
U tom slučaju nije bitno kako su orijentirane X osi elemenata.
In that case, it does not matter how X axes of elements are oriented.

GENERIRANJE UTJECAJNIH LINIJA
GENERATING INFLUENCE LINES

[Wed Dec 17 11:23:50 2003]
Striktno govoreći, generiranje utjecajnih linija ne pripada k području modeliranja konstrukcija, ali služi pri oblikovanju serija opterećenja, kako bi se dobili maksimalni utjecaji bilo reznih sila ili deformacija u pojedinim presjecima elemenata strukturalnih sustava.
Strictly speaking, generation of influence lines does not belong to the area of structural modeling, but it is used in the formation of series of loads, in order to obtain maximum influences whether of cutting forces or deformations, in certain element sections of structural systems.

[Wed Dec 17 11:28:53 2003]
Naročito se utjecajne linije koriste u definiranju niza shema pokretnih opterećenja mostova.
Influence lines are particularly used in defining series of schemes of moving loads of bridges.

[Wed Dec 17 11:29:59 2003]
Kod složenih strukturalnih sklopova to je izvanredno važno, kako bi se u svim presjecima svih elemenata mosta odredili maksimalni utjecaji reznih sila ili/i deformacija, uzrokovanih prolazećim pokretnim opterećenjem (propisanim shemama opterećenja) na mostu.
In complex structural assemblies this is extremly important, so that in all sections of all bridge elements maximum influences of cutting forces or/and deformations could be determined, caused by passing moving load (specified with load schemes) on the bridge.

[Wed Dec 17 11:36:45 2003]
Ova su opterećenja standardizirana i ovise o namjeni mosta.
These loads are standardized and they depend upon the purpose of the bridge.

[Wed Dec 17 11:37:03 2003]
Mostovi mogu biti cestovni (tu postoje velike razlike između mostova na rangiranim cestama i mostova na autocestama), željeznički, pješački i za laka vozila.
Bridges can be road bridges (there are great differences between bridges on ranked roads and bridges on motorways), railroad bridges, pedestrian bridges and bridges for light vehicles.

[Wed Dec 17 11:37:03 2003]
Postoje i mostovi posebnih namjena
There are also bridges for special purposes

U skriptama Nosive strukture, Liber, 1979, potanko su objašnjene metode konstruiranja utjecajnih linija korištenjem kompjutorskih programa
In lecture notes Bearing structures, Liber, 1979, there are detailed explanations of methods for designing influence lines with computer programs

[Wed Dec 17 12:46:20 2003]
Ovdje će se spomenuti samo način generiranja utjecajnih linija za bilo koju statičku veličinu, za jedan relativno jednostavni sustav (kontinuirani nosač s dva raspona, s konstantnim poprečnim presjekom nosača), koristeći poznati (stari) paket STRESS.
We will mention here only a method of generating influence lines for any static size, for a relatively simple system (continuous beam with two spans, with the constant cross section of the beam), using the familiar (old) package STRESS.

[Wed Dec 17 12:46:20 2003]
Bitno je podijeliti nosač na što više odsječaka, kako bi se dobila što bolja aproksimacija krivulja utjecaja
It is important to divide the beam into as many segments as possible, in order to obtain better approximation of influence curves

[Wed Dec 17 12:55:55 2003]
Prikazuje se oblikovanje ulaznih podataka za generiranje utjecajnih linija reakcija za dani statički sustav jednog mosta.
It presents the formation of data input for generating influence lines of reactions for the given static system of one bridge.

[Wed Dec 17 12:55:55 2003]
Mjere i dimenzije su hipotetske
Measures and dimensions are hypothetical

[Wed Dec 17 13:02:22 2003]
Utjecajne linije za reakciju formiraju se simulacijom jediničnog slijeganja ležaja u smjeru željene reakcije (općenito nalozima JOINT DISPLACEMENT)
Influence lines for reaction are formed by simulating unit settlement of a bearing in the direction of the desired reaction (generally, with commands JOINT DISPLACEMENT)

[Wed Dec 17 14:18:08 2003]
Utjecajne linije reznih sila i/ili deformacija dobiju se na sličan način formiranjem setova opterećenja jediničnih sila.
Influence lines of cutting forces and/or deformations are obtained in a similar manner, by forming the sets of loads of unit forces.

[Wed Dec 17 14:19:52 2003]
Ova posebna jedinična opterećenja prilažu se kao JEDINIČNE sile u čvorovima nosača.
These special unit loads are added as UNIT forces in beam nodes.

[Wed Dec 17 14:22:45 2003]
Rezultati su reakcije, rezne sile u presjecima i deformacije (progibi, pomaci, rotacije presjeka u čvorovima).
Results are reactions, cutting forces in sections and deformations (deflections, displacements, rotations of sections in nodes).

[Wed Dec 17 14:22:45 2003]
Posebno traženim formama ispisa ovi sračunati rezultati oblikuju utjecajne linije za te tražene statičke veličine
With separately required forms of printout, these calculated results form influence lines for those searched static sizes

[Wed Dec 17 14:31:49 2003]
Na priloženoj slici prikazano je formiranje takvih setova jediničnih sila, te na kraju generiranje triju utjecajnih linija za momente savijanja u tri presjeka nosača (2, 3 i 7).

[Wed Dec 17 14:34:56 2003]
U programu MSTRUDL postoji poseban nalog za generiranje utjecajnih linija korištenjem generatora pokretnog opterećenja
In MSTRUDL, there is a special command for generating influence lines with the use of moving load generator

[Wed Dec 17 15:34:40 2003]
Moguće generiranje utjecajne linije za momente savijanja u presjecima/čvorovima 2, 3 i 7
Possible generation of influence lines for bending moments in sections/nodes 2, 3 and 7

[Wed Dec 17 15:42:47 2003]
Naravno, na ovaj se način mogu generirati utjecajne linije i za vrlo složene statičke sustave (u ravnini i u prostoru).
Naturally, in this way we can generate influence lines for very complex static systems (in a plane and in space).

[Wed Dec 17 15:49:27 2003]
Prikazuje se jedna utjecajna ploha roštiljnog mosta.
Influence surface of a grid bridge is shown.

[Wed Dec 17 15:56:01 2003]
Nakon što je generirana utjecajna ploha za neku statičku veličinu, tu utjecajnu plohu treba i opteretiti odgovarajućim standardnim pokretnim opterećenjima kako bi se dobili najveći pozitivni i negativni utjecaji, a što predstavlja, i uz mogućnost automatske generacije opterećenja vozilima, ipak znatan fizički posao upisa podataka i generiranja envelopa.
After an influence surface for some static size is generated, this influence surface must be loaded with adequate standard moving load in order to obtain maximum positive and negative influences, which is, nevertheless, even with the possibility of automatic load generation with vehicles, significant manual work of data input and envelop generation.

[Wed Dec 17 16:01:45 2003]
Naime, ako se zna da za niz presjeka svakog elementa (obično se elementi dijele na deset ili dvadeset dijelova) treba konstruirati utjecajne linije (ili utjecajne plohe) za statičke veličine (općenito za N, M, T rezne sile), onda je jasno da takvih utjecajnih linija (ili ploha) ima vrlo mnogo.
That is, if we know that for series of sections of every element (elements are usually divided into ten or twenty parts) influence lines (or influence surfaces) must be constructed for static sizes (generally for N, M, T of the cutting force), it is clear then that there are many such influence lines (or surfaces).

[Wed Dec 17 16:04:30 2003]
Ako se za svaku statičku veličinu u presjeku mora naći maksimalni pozitivni i negativni utjecaj, onda se odmah i uviđa koliki je to fizički posao kojeg treba obaviti pri generaciji opterećenja konstrukcije mosta.
If for every static size in the section we must find the maximum positive and negative influence, we can immediately realize the amount of manual work which has to be performed when generating load of bridge structures.

[Wed Dec 17 16:04:30 2003]
Unatoč kompjuterizaciji taj se obiman posao ne može za sada izbjeći u današnjem dizajnu mostova
In spite of computerization, this extensive work still cannot be avoided in contemporary bridge design
