装配式建筑单元设计及其结构试验研究

Research on the design elements of prefabricated building system and the structural tests

针对装配式建筑体系中剪力墙在施工方面存在的困难,设计了一种由梁和上、下半墙组成的半体剪力墙单元,为了研究其结构抗震性能,文中对2个现浇剪力墙和1个预制装配式剪力墙进行了低周反复荷载试验,分别研究了预制装配式剪力墙与现浇剪力墙的破坏形态、滞回曲线以及承载能力。试验结果表明:施工缝位置对结构的影响更大,半体剪力墙通过合理的连接方式能够满足建筑与结构的要求。

For the difficulty of shear wall construction the prefabricated building system,this paper introduced a new building unit,which includes beam,the upper half and lower half of the wall.To study its performance,two situ shear walls and a prefabricated shear wall were tested under cyclic loading.The failure modes,hysteresis curves and carrying capacity of the prefabricated shear walls were analyzed.The experimental results showed that the construction joints have a larger influence on the structure.The half shear wall unit with reasonable connection could meet the requirements of structures through the structural experiments.
