Abstract

One aspect of PERFORMANCE BASED EARTHQUAKE ENGINEERING (PBEE) is to allow comparison between different designs and RETROFIT solutions using estimation of COLLAPSE PROBABILITY. To investigate this process, case study was performed on the weak RC frame that has been RETROFITted with two different methods, e.g., brace and cylindrical friction damper. Models of case studies were defined in OpenSees software. Then 15 ground motions were selected and Incremental Dynamic Analysis (IDA) was conducted on models. The performances of buildings were evaluated by using a probabilistic analysis. The results show that the RETROFIT methods reduce the probability of exceeding of the limit states 1IO and 2CP. However, considering site-specific seismic hazard curve in which the reduction of structure period was included, the different results were obtained. In this study, although the damage probabilities for a specific hazard level for both RETROFITting schemes were reduced, the COLLAPSE PROBABILITY of the structure RETROFITted with braces increased in comparison with the initial structure.
