Abstract In shaking table tests, appropriate boundary conditions are required in order to simulate semi-infinite seismic soil deposit responses within a finite size soil container. In this study, a laminar shear container with variable stiffness, constructed with a stack of steel hollow frames supported by ball bearings and bolts, was designed. The stiffness of the container can be changed by adjusting the number of frame, and row of bolts, and the connection form of bolts. Ten cases of shaking table tests were performed in order to determine the fundamental frequency of the sand deposit and to investigate boundary effects of the container. Results showed that the newly constructed laminar container has little boundary effects on the soil and is able to maintain the in-plane free-field response.

振动台试验用层流剪切容器的设计与性能

摘要 在振动台试验中，为了模拟有限尺寸土壤容器内的半无限地震土壤沉积响应，需要适当的边界条件。在这项研究中，设计了一个具有可变刚度的层流剪切容器，它由一堆由滚珠轴承和螺栓支撑的钢空心框架构成。集装箱的刚度可以通过调整框架的数量、螺栓的排数和螺栓的连接形式来改变。进行了 10 次振动台试验，以确定砂沉积的基本频率并研究容器的边界效应。结果表明，新构建的层流容器对土壤的边界影响很小，能够保持面内自由场响应。
