Abstract
Građevine s mekim katom podložne su urušavanju i predstavljaju jedan od najopasnijih tipova visinski nepravilnih konstrukcija. U teorijskom dijelu rada prvo je kratko objašnjen fenomen mekog kata i dani su neki razlozi zbog kojih ova pojava nosi značajan rizik. Građevine s mekim katom zatim su objašnjene s arhitektonske i inženjerske točke gledišta, dan je kratak povijesni pregled značajnih istraživanja vezanih uz meke katove, podjela ovih građevina, kao i mjere ublažavanja. U praktičnom dijelu rada provedena je nelinearna dinamička analiza na ravninskim okvirima s mekim katom. Prvo je definiran osnovni numerički model konstrukcije – šesterokatni armirano-betonski okvir bez zidane ispune. Na temelju osnovnog modela izvedeno je sedam varijanti sa ispunom - šest sa diskontinuitetom zidane ispune koji se razlikuju po etaži i jedan sa zidanom ispunom na svim katovima, tako da je za potrebe seizmičke analize izrađeno ukupno osam različitih modela. Na modelima je provedena nelinearna dinamička analiza pomoću vremenskih zapisa sedam zabilježenih potresa. Uspoređeni su dobiveni uprosječeni rezultati i dan je grafički prikaz međukatnih pomaka za svaki pojedini model. Utvrđeni su optimalni i kritični model, kao i odnos između visinskog položaja mekog kata u građevini i veličine maksimalnog međukatnog pomaka. Na kraju su isprobane mjere koje bi ublažile utjecaj mekog kata na kritičnom modelu.
Abstract (english)
Soft storey buildings are susceptible to collapse and represent one of the most dangerous types of vertically irregular buildings. In the theoretical part of the thesis, the soft storey phenomenon was first briefly explained and reasons why this occurrence carries a significant risk were given. Soft storey buildings were then presented from an architectural and engineering standpoint, and a brief historical overview of significant research related to soft storeys, classification of these buildings, as well as mitigation measures were given. For the practical part of the thesis, nonlinear dynamic analysis was carried out on plane frames with soft storeys. First, the main numerical model of the structure was defined - a six-storey reinforced concrete frame without infill walls. Based on the main model, seven variants with masonry infill were derived – six with infill discontinuity that differs by level and one with infill on all levels, so a total of eight different models were made for the purpose of seismic analysis. Nonlinear dynamic analysis was carried out on the models via the time-history method, using accelerograms of seven recorded earthquakes. The obtained averaged results were compared and a graphic representation of inter-storey drift ratio for each individual model was given. Optimal and critical model were determined, as well as the relation between the elevation of the soft storey in the building and the maximum inter-storey drift ratio. In the end, an attempt was made at mitigating the soft storey effect for the critical model.
