Performance-based Seismic Design of reinforced concrete Structure - A Review

Abstract

In recent times, in multistory buildings, the seismic demands were met using the code-based method of seismic analysis and design of the structure ,although the design of building can be more optimized by a more modern and realistic design approach in the form performance based design .As per the code, the building performance under seismic response are categorized into different levels of performance checks for the actual ground motions or some sets of ground motions ,limiting the global damage and thereby creating a scope for optimization at material level and at cross section level of the reinforced concrete structure .The building can be designed or checked based on this code prescribed performance levels, reducing the potential risk of the future earthquake as well as the damage or the loss caused due the earthquake. This review paper highlights numerous studies done by researchers comparing the responses from the code-based design and performance-based design, paving the way for use of performance-based design in the structure.
