摘要

Nowadays, seismic hazards increase day by day; it is not possible to stop any hazard, but the buildings can be strengthened. This study developed a framework for evaluating seismic reliability by considering six RC building models through analysis. The models include regular as well as irregular buildings with shear walls, bracings, dampers, and base isolation. Initially, three seismic response parameters were evaluated, such as storey drift, storey displacement, and base shear for all models. Three multi criteria decision making (MCDM) consisting of the Best Worst Method (BWM), Analytic Hierarchy Process (AHP), and Fuzzy AHP, were employed to quantify the importance of these parameters. The probability of reliability of each model were evaluated with the help of MCDM tools and the Weighted Sum Method, the reliability and probability of reliability of each model were evaluated. Model 2, consisting of dampers, shear walls, and bracings, exhibited the highest seismic reliability and lateral stiffness. A regular building with base isolation was considered as Model 3, where an increase in flexibility and a decrease in reliability were obtained. Moderate seismic performance was obtained from the irregular C-shaped and I-shaped models. Base shear was considered the most important seismic response parameter, followed by storey drift and displacement for all three MCDM tools. For reinforced concrete (RC) structures, nonlinear seismic analysis combining MCDM tools facilitates reliable structural performance evaluation in the proposed framework.
