In the context of earthquake engineering, nonlinear response history analysis is an important tool to predict with reasonable accuracy the building response for varying levels of ground motion intensity. Ideally, the nonlinear response history analysis should faithfully simulate all significant modes of deformation and deterioration in the structure from the onset of damage up to collapse. However, given present analysis technologies and the practical constraints of design, it is usually not feasible and perhaps not warranted to directly simulate all significant nonlinear effects in analysis. Acceptance criteria for both individual components and the overall system must be tailored to the specific analysis capabilities for simulating nonlinear response. In this study, nonlinear response characteristics of the simple structure are examined with respect to three-nonlinear component models. The objective of this paper is to propose most appropriate nonlinear component models through a comparative analysis of top floor displacement and element force on the actual structure subjected to Elcentro earthquake.
