This study evaluates the accuracy of an equivalent linear model in predicting peak nonlinear time-history displacement seismic isolation systems with single friction pendulum bearings. To perform this evaluation, dynamic response numerical models 120 subjected to 390 strong earthquake ground motions, including motions pulse and without pulse, was analyzed statistically processed. The results show that can partly predict its counterpart model. However, also underestimate or overestimate displacement. On average sense, underestimates small overestimates large It is observed relationship between displacements depends on motion types. Based analysis data, equations representing at different reliable levels for types were proposed. These be used practice.
