摘要
为了研究钢—混凝土组合结构体系的抗震性能，对钢—混凝土组合梁在低周反复荷载作用下的性能进行了试验研究。在试验研究的基础上，考虑了剪力连接程度的影响，建立了钢—混凝土组合梁的恢复力模型，并编制了相应的计算程序。计算结果与实测值吻合良好，建议的模型对钢—混凝土组合梁的抗震设计具有较好的参考价值。
In order to investigate the seismic resistant performance of composite steel concrete structures widely used in tall buildings and heavy plant structures in China, the experiments were conducted on composite steel concrete beams under repead loading and cyclic loading. Based on the test results and analysis, restoring force model of composite steel concrete beam was established with consideration of the degree of shear connection. According to the proposed model, a computing programe was made. The calculated results show the good agreement with the measured restoring force model. The proposed model can be applied to the aseismatic analyses and design of composite steel concrete beams.
