摘　　要：近年来,研究发现地震中非结构构件破坏带来的损失远远大于结构体破坏的损失,开展非结构构件的抗震性能研究日益得到重视。地震模拟振动台模型试验是检验结构抗震性能的最直接手段,它也常用于加速度相关型非结构构件(吊顶、水管支吊架、玻璃幕墙等)抗震性能试验。这类非结构构件往往在地震模拟试验中受到楼面响应谱的作用,如何准确复现非结构构件受到的楼面响应谱作用较少研究。本文在振动台离线迭代控制之外开发了基于楼面谱加速度波形再现的外环迭代控制器,构成了双层离线迭代控制架构,来克服非结构构件边界模拟装置(加载框架等)动力特性的影响。并采用这种方法进行了承压水管支吊架的抗震性能试验,试验结果表明这种方法可以较好地再现非结构构件受到的楼面响应谱作用,验证了方法的可行性。Recently,the studies find out that the loss of the failure of the nonstructural component is more than that of the structural body.So the nonstructural component seismic performance study is increasingly emphasized.Shaking table model test is usually used to test the seismic performance of acceleration-depended nonstructural component(e.g.ceiling,water pipe support and hanger,and glass screen wall etc.),which is the most direct methodto test structure seismic performance.However,this kind of nonstructural component is frequently acted upon by the floor response spectra during the shaking table test.There are very few studies on how to reappear the floor response spectra acting on nonstructure components accurately.In this paper,an acceleration floor response spectra reappearance offline iteration controller is developed outside of the shaking table inherent offline iterative control,which constitutes duoble-loop offline iterative control architecture to overcome the influence of dynamic characteristics of nonstructural component boundary simulator(Loading frame et al.).The seismic performance of the confined water pipe support and hanger shaking table test was conducted by using this method.The results show that this method can better implement the floor response spectra action on the nonstructure compoment.The feasibility of this method was validated.
