摘要
针对配筋混凝土砌块砌体框支剪力墙房屋子结构拟动力抗震试验,研究配筋混凝土砌块砌体框支剪力墙1∶4比例模型房屋设计与制作。综合考虑尺寸效应、构造措施、设备条件、经费可能等因素的影响,通过分析模型房屋所用材料的力学性能试验结果,以及与理论计算结果的比较,1∶4比例的模型房屋能够反映原型房屋动力性能。将原型房屋的截面和配筋,根据动力相似性原理,转换为1∶4比例模型房屋的截面和配筋,同时介绍了模型施工工艺以及所用材料。
In order to adopt substructure pseudodynamic aseismic test method in frame-supported reinforced concrete block masonry shear walls building,the design and construction of a 1∶4 scale frame supported reinforced concrete masonry shear walls building are investigated.The dimensions effect,details measure,installation term,and outlay condition are considered.The results of the material mechanics performance used by model building are analyzed and compared with the theoretical solutions.It is shown that the 1∶4 scale model building can respond the dynamic characteristic of the prototype building completely.Based on the dynamic similar principle,the member section and reinforcement of prototype building are converted into 1∶4 scale model building's.Moreover,the materials and construction methods are introduced.
