预制钢筋混凝土叠合剪力墙构件承载力的试验分析

Analysis of Experiment for Bearing Capacity of Composite Reinforced Concrete Wall

预制钢筋混凝土叠合剪力墙结构是产业化住宅的一种重要的结构形式。预制钢筋混凝土叠合剪力墙结构设计与一般的现浇钢筋混凝土剪力墙有所不同。文章对文献【3】所作的预制钢筋混凝土叠合剪力墙的低周反复荷载试验结果进行了分析,总结。对比分析了两种不同配筋形式的预制钢筋混凝土叠合剪力墙与同厚度的现浇钢筋混凝土剪力墙试件。分析了它们的极限承载力,延性,刚度的衰减过程,滞回曲线,耗能能力以及预制与现浇部分的协同工作特征。提出了在结构承载力,强度计算时将预制钢筋混凝土叠合剪力墙的预制外模板作为结构的外加荷载。而在计算结构刚度,控制建筑位移时可以考虑预制外模板的刚度贡献。并且认为,预制钢筋混凝土叠合剪力墙的配筋形式采取预制部分与现浇部分分开独立的配筋形式为佳。

The shear wall structure with composite reinfoced concrete wall is an important system in prefabricated concrete structures, the design of which differs from cast-in-situ reinforced concrete wall.In this paper, the author gives analysis about some mid-rise experiments in document[3], which include composite reinfoced concrete walls with two types of reinfocement and cast-in-situ reinforced concrete wall .based on some re- search.It includes the stiffness and its attenuation ,bearing capacity,ductility,hysteretie property, energy dissi- pation and synchronous behaviors between precast concrete form and cast-in-situ reinforced concrete wall.In this paper, the author introduces a method that consider the precast concrete form as a load while calculating the structure bearing capacity. However, the preeast concrete form was considered as a member of structure when calculating the stiffness of structure. The author also states that the type of separate reinforcement in precast form and cast-in-situ reinforced concrete wall is a better choice.
