Evaluation of is 1893-based design using the performance based earthquake engineering framework

Abstract

The performance-based earthquake engineering (PBEE) approach provides a framework to evaluate the performance of a structural system accounting for the uncertainties present in the different stages of modeling, design, and analysis. The framework typically comprises four stages of analysis�hazard, demand, damage and loss analyses�to evaluate performance. In the present study, the earthquake-resistant design of a frame and beam conforming to IS 1893�2000 is considered, and their performance is evaluated and presented in the form of probability of exceedance of damage. The first three stages of the performance evaluation are demonstrated using the method of incremental dynamic analysis to account for the record-to-record variability and further assuming the demand and damage fragility curves to have a lognormal distribution. The methodology presented to evaluate the performance of these structure helps in making decisions by accounting for the uncertainties present in each stage. � 2019, Springer Nature Singapore Pte Ltd.
