Earthquake is an uncertain catastrophe that may take place at any time instance and till now one cannot predict when it will occur. This catastrophe may cause mild or severe damage to the structure depending upon its intensity, which may result in loss of life. It is necessary to design the building for seismic forces to prevent its failure and to ensure safety of people by improving seismic performance of the building. For determining these forces different seismic demand assessment methods are used. These methods are given by different codes of practice such as the Indian code of practice, the American code of practice, the European code of practice and the New Zealand code of practice. For linear static analysis, the Equivalent Static Method and for linear dynamic analysis of building Response Spectrum Method is recommended by Indian code (IS-1893 Part 1). Codes other than Indian code also recommend nonlinear static and dynamic analysis by Pushover Analysis Method and Nonlinear Time History Analysis (NLRHA) for assessment of seismic demand of structure. Further, Nonlinear Time History Analysis is suggested as a standard tool for accurate seismic demand estimation. But this Nonlinear Time History Analysis Method has very complicated computation and it is a tedious one. So, the evaluation of a quick, precise and easy method for seismic demand estimation whose results should be almost near to Nonlinear Time History Analysis results was one of the challenging tasks for researchers. And this task is completed by researchers which resulted in Spectrum based Pushover Analysis (SPA) method. This paper presents overview of the advancement of seismic demand assessment method for different structures.
