［摘要］為提高裝配式結(jié)構(gòu)預(yù)制程度、解決剪力墻結(jié)構(gòu)連梁剪壓比不足問(wèn)題，保證結(jié)構(gòu)抗震性能，提出一種內(nèi)置壓型鋼板裝配式寬連梁。首先通過(guò)擬靜力試驗(yàn)研究了內(nèi)置壓型鋼板裝配式寬連梁剪力墻抗震性能，然后通過(guò)結(jié)構(gòu)數(shù)值模擬研究了采用該型連梁的12層剪力墻結(jié)構(gòu)在地震波作用下的動(dòng)力響應(yīng)。研究結(jié)果表明：內(nèi)置壓型鋼板裝配式寬連梁剪力墻試件在水平往復(fù)荷載作用下，發(fā)生彎剪破壞，延性較好、耗能能力較強(qiáng)，與現(xiàn)澆連梁的剪力墻結(jié)構(gòu)相比，采用壓型鋼板裝配式寬連梁剪力墻結(jié)構(gòu)抗震性能明顯改善。

Abstract:In order to improve the prefabrication degree of the fabricated structure, solve the problem of insufficient shear-compression ratio of the shear wall structure and ensure the seismic performance of the structure, a profiled steel sheet built-in fabricated wide coupling beam is proposed. Firstly, the seismic performance of profiled steel sheet built-in fabricated wide coupling beam structure was studied by pseudo-static test, and then the dynamic response of the 12-story shear wall structure using this type of coupling beam under the action of seismic waves was simulated through structural numerical simulation. The results show that the profiled steel sheet built-in fabricated wide coupling beam shear wall specimen undergoes bending-shear failure and has good ductility and strong energy dissipation capacity under the action of horizontal round-trip load, compared with the shear wall structure of cast-in-place coupling beams, the seismic performance of the profiled steel sheet built-in fabricated wide coupling beam structure is significantly improved.

Keywords:profiled steel sheet built-in fabricated wide coupling beam;shear wall structure;seismic performance;dynamic response
