双面叠合剪力墙叶板连接形式对构件受力影响的分析

Analysis of Influence of Blade Plate Connection Form of Double-sided Laminated Shear Wall on Force of Components

双面叠合剪力墙由两侧预制混凝土叶板和中间后浇混凝土叠合层组成,因其节省模板,减轻自重利于吊装,故应用前景广阔。传统叠合剪力墙一般使用桁架筋对两侧叶板拉结,但随着研究发展,三一筑工研发的SPCS体系叠合剪力墙开始采用预制钢筋笼对叶板拉结。围绕这2种连接形式,采用通用有限元软件Abaqus进行建模分析,在2种轴压比下,提取应力云图和滞回曲线,根据计算结果分析不同叶板连接形式对构件受力造成的影响。

The double-sided laminated shear wall is composed of precast concrete blade plates on both sides and a laminated layer of post-cast concrete in the middle.Because it can save formwork,reduce self weight and facilitate hoisting,it has a broad application prospect.The traditional lami nated shear wall gen erally uses truss bars to tie the two sides of the blade plate,but with the development of research,the SPCS system composite shear wall developed by SANY Construction Engineering began to use prefabricated steel cage to tie the blade plate.Based on these two connection forms,the general finite element software Abaqus is used for modeling and analysis.Under the two axial compression ratios,the stress nephogram and hysteretic curve are extracted.According to the calculation results,the in fluence of different blade plate conn ection forms on the force of compone nts is analyzed.
