DYNAMIC INELASTIC NUMERICAL SIMULATION ON A SHAKING TABLE TEST OF A FULL SCALE STEEL MOMENT FRAME
A shaking table test of a full scale steel frame was carried out on E-Defense, the worlds largest earthquake simulator. A Bind Analysis Contest was held prior to the test. Based on OpenSEES which stands for Open System for Earthquake Engineering Simulation, a dynamic nonlinear numerical simulation of the 4-story full-scale steel moment frame structure is presented in this paper. Fiber model with fewer DOFs is used in structure element simulation by taking the P-Delta effect into account. After proofreading with the same structure modeled in SAP2000, the responses of the structure under frequent, moderate and severe ground motions are predicted prior to the full-scale shaking table test. Compared with the experimental results, the analytical results validate the accuracy of the numerical simulation method, in both the inelastic behavior and the failure mechanism. The seismic responses and the collapse moment under severe ground motion are accurately predicted. The failure mechanism is formed due to the decrease in the lateral stiffness of the structure, which is caused by local buckling at the ends of the columns. The study establishes the validity of the inelastic analysis method of overall structure based on fiber model, which is suitable for seismic analysis.
