NELINEARNA STATIČKA ANALIZA PONAŠANJA POSTOJEĆE ZIDANE ZGRADE NA POTRESNO DJELOVANJE ; NONLINEAR STATIC ANALYSIS OF THE BEHAVIOR OF AN EXISTING MASONRY BUILDING UNDER SEISMIC ACTION
Na području Hercegovine nalazi se veliki broj zidanih objekata, čija starost premašuje 50 godina. Uglavnom se radi o manjim objektima, s jednom do dvije etaže, dok su nosivi zidovi uglavnom od obrađenog kamena u vapnenom mortu. Malo kasnije javljaju se i veći objekti s nosivim zidovima od opeke, i betonskih blokova u produžnom mortu. Stropne konstrukcije uglavnom se sastoje od drvenih hrastovih greda, oslonjenih na nosive zidove, s daščanom oplatom s gornje strane i mortom, po pletivu od trske, s donje strane. Takve konstrukcije su iznimno osjetljive na potresno djelovanje, te gotovo sigurno ne bi mogle izdržati projektno potresno opterećenje, bez značajnih oštećenja i rušenja. U ovom radu izvršena je nelinearna statička analiza konstrukcije jednog takvog objekta. U prvoj analizi izvršena je provjera postojećeg stanja, a u drugoj provjera djelomično ojačane konstrukcije. Iz analize je vidljivo da takvo ojačanje značajno poboljšava nosivost, dok je povećanje deformabilnosti (duktilnosti) znatno manje zbog jako velike krutosti ovakvih konstrukcija. ; In the territory of Herzegovina there is a large number of masonry buildings, the age of which exceeds 50 years. These are mostly smaller buildings, with one to two floors, while the load-bearing walls are mainly made of cut stone in lime mortar. Larger buildings with load-bearing walls made of bricks and concrete blocks in cement-lime mortar appeared a little later. The floor structures mainly consist of timber oak beams, supported by load-bearing walls, with boarding on the upper side and plaster, on reed netting, on the lower side. Such structures are exceptionally sensitive to seismic action, and almost certainly could not withstand the design seismic load without significant damage and collapse. A nonlinear static analysis of the structure of one such building was performed in this paper. A check of the existing condition was performed in the first analysis, and a check of the partially strengthened structure in the second. It is evident from the analysis that ...
