摘要

Two models are tested on a shake-table. One of the models is a normal reinforced concrete megaframe structure and the other is a multifunctional vibration-absorption reinforced concrete megaframe structure in which the laminated rubber bearings are placed between the major frame and the minor frames. Two earthquake motions (the El Centro wave and the Taft wave) are used during the test. This paper presents the dynamic characteristic, the seismic responses and the failure mechanism of these two models under varying peak acceleration levels for each of the earthquake motions. The test results demonstrate that the aseismic behavior of a multifunctional vibration-absorption reinforced concrete megaframe structure is much better than that of a normal reinforced concrete megaframe structure.
