Finite element analysis of spatial steel frame structure

Zadatak ovog rada bio je statiĉka analiza prostorne ĉeliĉne okvirne konstrukcije metodom konaĉnih elemenata. Zadanu konstrukciju modelirali smo u programu ConSteel12 te povećali opterećenje za 20%. Nakon što smo napravili analizu i globalne provjere primjetili smo da konstrukcija ne zadovoljava uvjete po Eurokod 3 normi te smo radili preinake na konstrukciji. Dodali smo grede na rubove konsturkcije da rasteretimo preiskorištene elemente. Na taj naĉin riješili smo problem i konstrukcija sad zadovoljava sve potrebne uvjete.The task of this paper was the statistical analysis of spatial steel frame construction by the finite element method. We modeled the default construction in ConSteel12 and increased the load by 20%. After we have made an analysis and global checks we noticed that the construction did not meet the requirements of Eurocode 3 standards and we have made some modifications to the construction. We added beams at the edges of the constriction to dislodge the pre-used elements. So we solved the problem and now the construction meets all the necessary conditions
