Abstract:

In this study, the multiple-spring (MS) model with the curve-approximated hysteresis rule is proposed for the nonlinear seismic response simulation of bidirectionally loaded hollow square-section steel columns such as cantilever type steel piers. To represent the nonlinear hysteresis behavior of the column, an effective and simple optimization procedure is introduced to identify the free parameters of the model. A parameter determination approach for approximate modeling in preliminary design calculations is also introduced. The results of quasi-static and pseudodynamic tests using bidirectional loading are compared with the simulation results to verify the accuracy of the proposed model. The proposed method is shown to be advantageous in achieving accurate simulation of the seismic response of a bridge model involving bidirectionally loaded steel columns, especially the hysteretic force-displacement relationship and time history of the dynamic response. © 2017 American Society of Civil Engineers.
