V magistrskem delu smo obravnavali različne konstrukcijske sisteme lesenih stavb. Predstavili smo posamezne sisteme in opisali prenos vertikalnih in horizontalnih sil. Za izbran nosilni sistem smo izdelali statično in dinamično analizo. Obravnavali smo enodružinsko stanovanjsko hišo. Na podlagi idejne zasnove smo se odločili za okvirno nosilno konstrukcijo. Zasnovali smo jo iz pretežno lesenih elementov, nekaj pa je jeklenih. Vertikalna obremenitev se prenaša preko členkasto povezanih gred in stebrov, horizontalna obremenitev pa preko lesenega in jeklenega povezja. Statično in dinamično analizo modela nosilne konstrukcije smo izvedli s pomočjo programske opreme Scia Engineer. Statične vplive smo določili na podlagi veljavnih standardov SIST EN 1991-1:2004. Prereze elementov nosilne konstrukcije smo dimenzionirali za merodajno obremenitev po metodi mejnih stanj nosilnosti in mejnih stanj uporabnosti. Obremenitev zaradi potresne obtežbe smo določili z uporabno modalne analize. Nosilnosti elementov smo preverili na potresno obremenitev. Dimenzionirali smo pomembnejše spoje, izvedene s pomočjo jeklene pločevine, ki elemente povezuje med seboj. Izrisali smo pozicijske načrte. Various types of timber loadbearing construction were analyzed in this master’s thesis. All of the systems were described individually and the transfer of vertical and horizontal load was shown. Static and dynamic analysis was performed on a single-family detached house for the selected loadbearing system. Regarding the conceptual design a heavy timber frame was selected as the type of loadbearing construction. The timber frame was designed using mainly timber and some steel elements. Vertical loads are transferred through rotationally joined columns and beams, while horizontal loads are transferred through timber and steel bracing. The static and dynamic loadbearing analysis was performed using Scia Engineer software. The load was analysed according to the valid SIST EN 1991-1:2004 standard. The relavant strain on the timber and steel was checked for both the ultimate limit and the serviceability limit state. Seismic load was calculated using modal analysis. Checks of individual construction elements were once again made for seismic load combinations. Design and check of significant joint was performed. Most of them were designed using a steel plate, which connects the elements together. Drawings were made of the assembly. |
