COMPARISON OF RESULTS BETWEEN SHAKING-TABLE TEST AND FEM ANALYSIS ON A COMPLEX HIGH-RISE BUILDING
The partial frame-supported shear wall structural system is applied to a 49-storey apartment building. As a complex girder transfer structure is used and several indexes exceed the limitation of current design codes, the building belongs to special complex high-rise building. In order to investigate the seismic behaviour of this structure, a 1:20 scale model is fabricated and tested in a large-scale shaking-table. The total weight of this model is 59.9t, and the similarity radio of acceleration descends to 1.69. It is one of the largest shaking-table tests in china, by which the shear strength of vertical components can be accurately estimated. Three seismic waves were adopted in the test, which were The EI-CENTRO, LIVERMOR and an artificial one. The shaking-table test was carried out under 7 kinds of seismic level and 59 cases. It can be observed from the results that some components were damaged under 8 degree severe earthquake and the model began to collapse under 9 degree severe earthquake. Moreover, the seismic responses of the model are analyzed by finite element analysis program-Sap2000. By comparing the results between the analysis and the tests, the dynamic properties, dynamic time history, acceleration response, relative displacement response,inter-story drift response, torsion response of the structure were discussed. It is concluded that the analysis method used here can simulate seismic responses of the structure effectively.
