Introduction
Over the last few decades, it has been found that the traditional procedures, which are based on elastic linear analysis, can only approximately estimate the typically nonlinear seismic response. Therefore, the inelastic methods of analysis have been gradually introduced into practice in order to estimate the seismic response more realistically. Contrary to the elastic linear methods which can only implicitly predict the performance, the objective of the inelastic seismic analysis procedures is to directly estimate the magnitude of inelastic deformations.
In general, the most refined and accurate inelastic method is the nonlinear response history analysis (NRHA). Nevertheless, it is only sporadically used in the design practice, since it is, for the time being, still too complex for regular use. It requires substantial experience and knowledge about the modeling of the dynamic response of structures and seismic...
