Abstract
In this research, a reduced scale model of the composite high-rise building with steel reinforced concrete column, steel beam and reinforced concrete core tube was designed and tested by using the shake table test technology. The acceleration and displacement of the model were measured during the tests. The cracking pattern and failure mechanism were illustrated. Above the shake table test, the finite element analysis of the test mode was carried out. The main effort of the numerical analysis was focused on the selection of the nonlinear models. Based on the experiment results and the strategy of considering nonlinear property of the beam-column joint and the short beam of the concrete core wall were proposed. It is proved that the proposed strategy is effective and economical for seismic behavior assessment of such composite high-rise building structure system.
