摘　　要：对地震作用下建筑结构的振动控制问题进行了研究 ,给出了基于趋近律方法的变结构闭环抗震控制方法 .算例分析结果表明 ,该控制方法能有效地减小结构的地震响应 。In this paper,the active control approaches by using the variable structure control theory are studied for applications to seismically excited building structures.Based on the constant plus proportional rate and the power reaching law method,two kinds of feedback controllers are presented.The simulation results are obtained for a MDOF shear building equipped with active brace system(A B S)under seismic excitations.It is found that the variable structure control methods presented in this paper are effective.
