Sažetak
In this paper we proposed methodology for seismic vulnerability assessment of masonry buildings with flexible floors. The methodology is based on the calculation of Damage index (DI), a numerical value indicating the level of structural damage. The structure is represented using an SDOF model determined by weight, elastic base shear capacity, damping, elastic stiffness and post-elastic stiffness. Using accelerograms of earthquakes, step by step time-history numerical integration can be provided along with the results: top displacements, yield excursions, cumulative energy and base shear–displacements. These results serve as parameters which are then input in the formula for DI. This methodology was verified for RC frame and wall structures and the spectral functions of DI (plot of a number SDOF models with different fundamental periods) were created for RC framed structures. The aim of this study is to extend the current research of Morić considering seismic vulnerability of masonry buildings and to create spectral functions of DI for URM with flexible floors.
