Corrosion of steel is one of the most important potential dangers and threats in concrete structures. Corrosion of steel embedded in reinforced concrete plays a key role in reducing the strength and durability of reinforced concrete. Several studies have proposed that alternative approaches to enhancing the performance of reinforced concrete and its resistance to corrosion. In this study, the r...

Direct displacement-based design is a nonlinear static procedure and has to check the suitability of method against different types ground motions namely far field, near field forward directivity fling step. The applied for buildings supported on fixed base hysteretic isolation bearings. Seismic isolators are provided between foundation superstructure minimize influence motion superstructure. f...

An efficient optimization approach is described to calibrate load factors used for designing of structures. The load factors are calibrated so that the structural reliability index is as close as possible to a target reliability value. The optimization procedure is applied to find optimal load factors for designing of structures in accordance with the new version of the Mexico City Building Cod...

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...

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...

abstract: Due to the paucity of studies regarding seismic assessment buildings in Brazil, this study aims present and discuss a reliability reinforced concrete framed structure designed according Brazilian standard ABNT NBR 6118:2014 without consideration design requirements 15421:2006. Herein, fragility functions are generated through probabilistic demand analysis, integrated with hazard curve...

corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (rc) structures deterioration in chloride-contaminated environments. as a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. the corrosion propagation phase is a ...
