Abstract: There is a strong need for evaluating the adequacy of seismic performance of civil engineering structures following the damage and collapse of numerous structures during recent earthquakes. In addition, the adequacy of seismic performance of the older structures in regions of high seismicity, which are designed prior to the advent of revised seismic deign codes, is also a matter of growing concern. Seismic performance evaluation of civil engineering structures is an iterative process involving alternate stages of experimentation and computation. Several experimental methodologies including quasi-static testing, effective force testing, shake table testing, pseudo dynamic testing and real time dynamic hybrid testing and computational methodologies based on different numerical time stepping procedures are used to simulate and evaluate the seismic performance of civil engineering structures. In this paper a broad overview on the existing computational and experimental seismic performance evaluation methodologies is reported. The paper also presents the genesis, development and mathematical formulation of the pseudo dynamic testing method in detail and highlights the merits and demerits of the method over the other experimental seismic performance evaluation methods
