Projekt tri etažne industrijske stavbe s poudarkom na potresni odpornosti : diplomska naloga

Kuštra, Jan (author), Sinur, Franc (mentor)

V diplomski nalogi obravnavamo zasnovo in dimenzioniranje tri etažne industrijske stavbe. Nosilno konstrukcijo predstavlja 9 pomičnih okvirjev z razponom 10 metrov na medosni razdalji 6 metrov. Horizontalna nosilnost v vzdolžni smeri je zagotovljena z ekscentričnimi povezji s srednje dolgimi strižnimi členi. Stropna konstrukcija je zasnovana kot sovprežna plošča, ki je podprta s sekundarnimi nosilci, ki so priključeni na primarne jeklene nosilce. Vplive na konstrukcijo smo določili v skladu s slovenskimi standardi SIST EN 1991 in SIST EN 1998. Konstrukcijo smo analizirali v računalniškem program SCIA Engineer 13.1. Globalna elastična analiza konstrukcije je bila izračunana s pomočjo dveh ravninskih okvirjev po teoriji drugega reda z upoštevanjem začetnih globalnih geometrijskih nepopolnosti. Potresna obtežna kombinacija je bila narejena po metodi horizontalnih sil. Konstrukcija je projektirana kot visoko duktilna, območja sipanja energije so predvideni v prečkah ter ekscentričnih povezjih, stebre varujemo. Za potresno dimenzioniranje je uporabljena t.i. metoda varovalke. V mejnem stanju uporabnosti smo preverili pomike, ki so se izkazali za skladne s standardom.

• Title: The project of a three storey industrial steel building with emphasis on seismic design

Abstract

The diploma thesis deals with the design of a three-storey industrial building. The supporting structure is represented by 9 moment resisting frames with a span of 10 meters which are 6 meters appart. Horizontal stiffness in the longitudinal direction is provided with eccentric bracings with medium lenght seismic links. The floor construction is designed as a composite concrete panel, which rests on the secondary beams, and is connected to primary steel beams. Effects on the structure were determined in accordance with Slovenian standards SIST EN 1991 and SIST EN 1998. The construction was analyzed in a computer program SCIA Engineer 13.1. The global analysis of the structure was calculated using two planar frames and elastic second order analysis taking into account global initial imperfections. Seismic loads were considered with lateral force method of analysis. The structure is designed as highly ductile. Dissipative areas are located in the beams and eccentric bracings. For ensuring the intended configuration of plastic hinges, the columns are protected after the capacity design method. The serviceability limit state was checked and defermations were in accordance with the standards.
