Potresna otpornost postojećih zgrada s dodatnim katovima od laganih drvenih konstrukcija ; Seismic resistance of existing buildings with added light timber structure storeys
U ovom se radu problem vertikalne nadogradnje razmatra u okviru analize potresne otpornosti građevina s dodanim katovima. Provedena je opsežna parametarska studija koja potvrđuje utjecaj broja dodanih katova i promjene njihove krutosti na potresni odziv građevina. Primjeri prikazani u radu pokazuju kako se krutost konstrukcija od laganih drvenih okvira i križno lameliranog drva lako može promijeniti mijenjanjem vrste i rasporeda spojnih sredstava. Poznati se postupci primjenjuju za izračunavanje krutosti zidnih elemenata lakog drvenog okvirnog sustava, a novi je postupak razvijen za određivanje krutosti križno lameliranih drvenih zidnih elemenata. U radu je prikazano kako promjena krutosti vertikalne nadogradnje može bitno utjecati na potresni odziv te da u nekim slučajevima takva nadogradnja može povoljno utjecati na potresnu otpornost, i to bez obzira na manje povećanje težine konstrukcije. ; In the presented paper, the problem of vertical expansions is treated in terms of seismic resistance of structures with added storeys. A large parametric study has been performed, confirming the impact of different number of added storeys, and the change of their stiffness, on the seismic response of structures. The paper shows examples of how stiffness in light timber frame and cross laminated timber structures can be easily altered just by changing the type and distribution of fasteners. Known procedures are used to calculate the stiffness of the wall elements of a light timber frame system, and a new procedure is developed for determining the stiffness of cross laminated timber wall elements. The study shows how changing the stiffness of the vertical expansion can have a significant impact on the seismic response and that, in some cases, vertical expansion can have a favourable effect on seismic resistance, despite a minor increase in the mass of the structure.
