Abstract Shaking table test is an effective method to study the soil-structure dynamic interaction under earthquake conditions. However, during the design process of the soil container, it is usually impossible to simulate the soil-structure dynamic interaction for three-dimensional (3D) seismic input. In this study, a cylindrical 3D laminar shear soil container was designed for use in the shaking table test. This soil container is composed of 1 base plate, 18 H-shaped laminar frames, 144 3D limit connectors, and 8 guardrails, with the characteristics including large stiffness, light weight, and 3D shear movement. The soil container simulates the free site boundary conditions and minimizes the boundary effect, which meets the requirements of the shaking table test to implement the soil-structure dynamic interaction during 3D seismic input. Moreover, a series of shaking table tests was performed to verify the performance test requirements of the container and to measure the seismic response of the soil. The results of this study indicate that the container does not impose significant boundary effects and is able to maintain 3D soil column behavior.

用于振动台的圆柱形 3D 层流剪切土壤容器的设计和测试验证

摘要 振动台试验是研究地震条件下土-结构动力相互作用的有效方法。然而，在土壤容器的设计过程中，通常无法模拟三维（3D）地震输入的土壤-结构动力相互作用。在这项研究中，设计了一个圆柱形 3D 层流剪切土壤容器，用于振动台试验。该土壤容器由1块底板、18个H形层状框架、144个3D限位连接件和8个护栏组成，具有刚度大、重量轻、3D剪切运动等特点。土壤容器模拟自由场地边界条件，最大限度地减少边界效应，满足振动台试验在3D地震输入过程中实现土-结构动力相互作用的要求。此外，还进行了一系列振动台试验，以验证容器的性能试验要求并测量土壤的地震响应。这项研究的结果表明，容器不会施加显着的边界效应，并且能够保持 3D 土柱行为。
