【摘要】 本文将拟动力实验方法应用于多点地震输入下的结构响应研究中，采用子结构技术解决了结构在多点地震输入下的实验问题。针对不同类型结构和不同方向的地震动输入，文中给出了相应的拟动力实验的数值积分方法。最后采用两点地震动输入对所提出的方法进行了实验验证，证明该方法的有效性。更多还原

【Abstract】 The pseudodynardc testing method with sulxtructure techniques is used in the structureres ponse research under multiple earthquake input. For different kinds of structures and ditTerent directintns of earthquake inputs, the pseudodynandc testing integration algnrithm is given. A verification test is carried out for two-point earthquake input. The testing re- sults show that the proposed methnd is suitable for the nonlinear response research of structure which is subjected to multiple earthquake excitation.更多还原
