中文摘要：
以天津西站典型结构为例，提取站厅结构主要单元，阐述可反映其抗震性能的振动台试验模型设计和制作方法。为保证试验结果可靠性，大跨钢桁架模型严格按照相似关系和等效原则设计，并采用8个相同的边桁架单元作为中间桁架单元的边界条件。比较试验模型和相应有限元模型的动力特性，明确所设计试验模型符合要求，能反映原型结构的竖向地震响应特征。
英文摘要：
The station hall of Tianjin west railway station was referred and adopted to extract the main structural units so as to elaborate the shaking table test model design and production which can reflect the seismic perform- ance. In order to ensure the reliability of test results, the long - span steel trusses model was designed in strict accordance with the similarity relation and equivalent principle, and eight same truss units were used to be the boundary conditions of the intermediate truss unit. Comparing the dynamic characteristics of the test model with the corresponding finite element model, it is sure that the design experiment model meets the requirements and reflects vertical seismic response characteristics of the prototype structure.
