In this work, we analyze the influence of masonry infill walls on the seismic performance of waffle slabs reinforced concrete (RC) framed structures. We analyze buildings of three, five and eight storeys, which are representative for a big number of housings in Barcelona, Spain. Capacity spectra have been obtained by performing pushover analyses and we have used a simplified procedure to obtain...

This study examines the fragility curves of a bridge by two different analytical approaches; one utilizes the time-history analysis and the other uses the capacity spectrum method. The latter approach is one of the simplified nonlinear static procedures recently developed for buildings. In this respect, a sample of 10 nominally identical but statistically different bridges and 80 ground-motion ...

in this paper, efforts are made to compare the safety of steel moment resistant frames designed according to different editions of the iranian code of practice for seismic resistant design of buildings. also, failure risk of a low and medium height frame which designed for high and low seismicity regions according to three editions of the code are evaluated. first, the testing cases were design...

In this paper, the dynamic behavior of square plates with various thicknesses and stiffening configurations subjected to underwater explosion (UNDEX) are evaluated through a relatively novel approach which is called Incremental Explosive Analysis (IEA). The IEA estimates the different limit-states and deterministic assessment of plats’ behavior, considering uncertainty of loading conditions and...

In this work fragility analysis of reinforced concrete and steel structures withinfill walls is performed.For this purpose a fuzzy-based fragility assessment framework for evaluating 3D framed structures is proposed taking into account various sources of uncertainty. In particular, randomness on the material properties and on the seismic demand is considered. The proposed framework requires the...

This research presents an alternative means of calculating vulnerability relations for buildings. Simulation-based fragility curves generated using a Monte Carlo simulation are usually not practical because of the large number of time-consuming analyses needed to obtain reliable statistics of the outcomes. This research implements a response surface metamodel to approximate complex analysis in ...
