Konstruiranje potresno odporne jeklene konstrukcije

Vesel Sitar, Nejc (author), Klemenc, Jernej (mentor)

V diplomski nalogi obravnavamo konstruiranje in analizo potresno odporne jeklene konstrukcije. Konstrukcija in njeni elementi so zasnovani na osnovi standarda o potresno odporni gradnji SIST EN 1998-1:2005 in pripadajočih dodatkov, analiza konstrukcije pa je izvedena v programskem okolju Abaqus. Za nosilne jeklene elemente konstrukcije je bilo izbrano jeklo S355, preračunana je bila projektna obtežba konstrukcije s pripadajočimi varnostnimi dodatki, analiza pa je pokazala, da konstrukcija s potresno izolacijo zdrži notranje napetosti, ki nastanejo od potresu. Primerno temu je bila dimenzionirana gumijasta potresna izolacija iz gume HDR, ki služi kot glavni element, za premagovanje potresnih obremenitev. Opravljena je bila tudi primerjalna analiza na neizolirani konstrukciji, preko katere smo določili efektivnost dušilnih elementov, ki je zmanjšala notranje napetosti v izolirani konstrukciji za 61,5%. Glavni doprinos diplomske naloge je prikaz procesa konstruiranja potresno odporne jeklene konstrukcije z dodatno potresno izolacijo ter analiza, s katero preverimo nosilne lastnosti konstrukcije in vpliv potresne izolacije.

• Title: Design of earthquake resistant steel structure

Abstract

The diploma thesis deals with the design and analysis of an earthquake-resistant steel structure. The structure and its elements are designed based on the standard for earthquakeresistant construction SIST EN 1998-1:2005 and its relevant annexes, while the analysis of the structure was carried out using the Abaqus software environment. Steel S355 was selected for the main load-bearing steel elements, the design load of the structure with corresponding safety factors was calculated, and the analysis showed that the structure with seismic isolation can withstand the internal stresses resulting from an earthquake. Accordingly, a rubber seismic isolation made of HDR rubber was dimensioned, serving as the main element for mitigating seismic loads. A comparative analysis of the non-isolated structure was also performed, through which the effectiveness of the damping elements was determined, showing a reduction of internal stresses in the isolated structure by 61,5%. The main contribution of the thesis is to demonstrate the process of designing an earthquakeresistant steel structure with additional seismic isolation and to analyze the load-bearing capacity of the structure and the influence of seismic isolation.
