Magistrsko delo obravnava potresno odporno projektiranje dvoetažne armiranobetonskelesene stavbe. Stavba je zasnovana tako, da sta spodnji dve etaži betonski, zgornji mansardni del pa je lesen. Betonski del konstrukcije je sestavljen iz sten in plošč. Stene so razporejene po obodu stavbe in okoli stopnišča ter dvigala. V nadstropjih je del konstrukcije previsen. Pri lesenem delu konstrukcije obravnavamo dve konstrukcijski zasnovi, ki ju med seboj primerjamo. Prvo zasnovo sestavljajo momentni okvirji, ki se členkasto pritrjujejo na betonski parapet, drugo pa stebri, ki so vpeti v betonski parapet, nanje pa se členkasto pritrjujejo špirovci. Horizontalno stabilnost druge zasnove dosegamo z leseno ploščo, ki predstavlja diafragmo strešne konstrukcije. Po rezultatih potresne analize se odločimo za drugo zasnovo, ki jo izboljšamo tako, da ji dodamo jeklena povezja. Magistrsko delo je razdeljeno na tri dele. V prvem delu je predstavljena konstrukcija, uporabljeni materiali in obtežba. Drugi del obravnava rezultate potresne analize in dimenzioniranje konstrukcije na potresno obtežbo, tretji del pa analizo in dimenzioniranje na stalna in začasna projektna stanja. Iz rezultatov analize ugotovimo, da s predvideno zasnovo zadostujemo pogojem mejnih stanj uporabnosti in mejnih stanj nosilnosti.

• Title: Earthquake resistant design of reinforced concrete - timber building

Abstract

Master thesis describes earthquake-resistant design of two story building with open loft space. Two stories are made of reinforced concrete, while loft is made of timber elements. Concrete part of the building consists of walls and slabs. Walls are distributed along the outer perimeter of the building, around the staircase and elevator. Building is cantilevered in upper stories. Two types of structural systems were investigated for the timber part of the building. First system consists of rigid frames which are hinged to concrete parapet. Second system consists of columns which are fully supported with concrete parapet. Roof beams are hinged to the columns. Horizontal stability of the structure is provided with timber slab, which acts as diaphragm of the roof structure. After seismic analysis we decide for second structural system, which is improved with steel bracings. Master thesis consists of three parts. The structure, materials and loads are described in the first part. Follows results of seismic analysis and design, while in the third part, the analysis and design of structure under permanent and variable loads are presented. Considering analysis results we come to the conclusion that the structural system meets requirements of ultimate limit states and serviceability limit states.
