【摘要】 由于砌体结构墙体中的竖向压应力对结构的强度和刚度都有一定的影响,因此其振动台缩尺模型设计与高层建筑的缩尺模型设计不尽相同,有着其独自的特点。以体外预应力加固砌体结构振动台模型对比试验为背景介绍了某四层砌体结构预制板教学楼缩尺模型设计的全过程,包括模型材料选取,模型相似关系的确定、模型保护措施的设计以及附加质量的确定,对其中存在的问题进行了讨论,所提供的砌体结构缩尺模型设计思路能为今后的相关试验工作提供一定的参考。更多还原

【Abstract】 Since the structural stiffness and strength of masonry structures are related to the compressive stress in the cross section of masonry walls,the shaking table test scaled model design of masonry structure is different from that of high-rise buildings and has its own distinguishing feature.Based on the shaking table tests for masonry structures strengthened using external prestressing technique,this paper describes the whole process of scaled model design for a four-tory school building in masonry structure with precast slabs,including the selection of materials,the determination of similitude parameters,the design of protective measures during tests and the determination of additional mass for the two models.The method applied in the model design can be used as a reference for the future similar experimental studies.更多还原
