Dynamic Inelastic Numerical Simulation for a Shaking Table Test of a Full Scale Steel Moment Frame Structure based on OpenSEES

摘要

This paper presents a Dynamic nonlinear numerical simulation of a 4-story full-scale steel moment frame structure based on OpenSEES. Fiber model which has fewer DOFs is used for structure member simulation. The responses of the structure under frequent, moderate and severe ground motions are predicted prior to the full-scale shake-table test. Correlated with the experimental results, the analytical results confirm the accuracy of the numerical simulation method, in both representing the inelastic behavior and the failure mechanism. The seismic responses and the collapse moment under severe ground motion are precise predicted. The study establishes the validity of the inelastic analysis method of overall structure based on fiber model, which is suitable for seismic analysis of overall structure.
