改进叠合板式剪力墙受力性能分析

摘要

The superimposed shear wall is a new assembly-type RC structure, it has been found more and more applications in building construction because of its adaptation to building industrialization. There are two common forms of superimposed shear wall:the superimposed shear wall with prefabrica-ted boundary element and with cast-in-situ boundary element. The superimposed shear wall with prefabricated boundary element is more convenient to the construction than superimposed shear wall with cast-in-situ boundary element. The superimposed shear wall with prefabricated boundary ele-ment is of much more practical value in actual production. The structural improvement of superim-posed shear wall is proposed. A simulation with OPENSEES finite element software was given to ana-lyze the behavior of improved superimposed shear wall. The analysis shows that the improved superim-posed shear wall not only has higher ultimate bearing capacity than unimproved superimposed shear wall, but also increases shear capacity of the interface of new-to-old concrete.%叠合剪力墙结构是一种新型的装配式结构,适应建筑工业化生产的要求,在建筑领域运用越来越广泛.现场常用的叠合剪力墙有两种形式,一种是边缘构件现浇的叠合墙体,一种是边缘构件预制的叠合墙体.边缘构件预制的叠合剪力墙施工更加方便,工厂化生产更具有优势,因此更加值得推广.针对边缘构件预制的叠合墙体,本文提出了一种改进形式.基于OpenS-EES采用对改进后的叠合板式剪力墙的受力性能进行模拟.模拟结果表明,改进的叠合剪力墙不仅能够提高叠合剪力墙的极限承载力,还能够增强墙叠合剪力墙界面抗剪能力.
