Numerical analysis of four-storey planar frame with semi-rigid connections

U ovome radu obrađena je numerička analiza četveroetažnog ravninskog okvira s apsolutno krutim, i FEP (Flush End Plate) polukrutim spojevima, metodom konačnih elemenata, prema normi Eurocode 3. Analiziran je utjecaj krutosti na statičku čvrstoću, stabilnost i slobodne neprigušene vibracije čelične konstrukcije upotrebom računalnog software-a ConSteel 14. Provedena je usporedba dobivenih rezultata, i doneseni su zaključci o implementaciji navedenih spojeva.In this paper the numerical analysis of four-storey planar frame with absolutely rigid and FEP (Flush End Plate) semi-rigid joints was performed based on finite element method, according to Eurocode 3 norme. The influence of connection rigidity on static strength, stability and free undamped vibrations of steel structure was analysed using ConSteel 14 computer software. A comparison of the obtained results was made and conclusions were reached on the implementation of these connections
