摘要: 介紹了雙面疊合夾心保溫剪力墻的體系發(fā)展及其構(gòu)造概況，并從保溫連接件選型、荷載和受力狀態(tài)方面對(duì)雙面疊合夾心保溫剪力墻開展了系統(tǒng)的分析。 此外，對(duì)雙面疊合夾心保溫剪力墻的抗震性能、溫度性能和澆筑工況性能進(jìn)行系統(tǒng)試驗(yàn)研究。 試驗(yàn)結(jié)果表明:雙面疊合夾心保溫剪力墻的承載力、位移延性、變形能力、耗能能力等主要抗震性能指標(biāo)與現(xiàn)澆對(duì)比試件相近，抗震性能優(yōu)良，可基本實(shí)現(xiàn)等同現(xiàn)澆設(shè)計(jì)；在溫度作用下，保溫連接件受力較大，但均可滿足承載力要求；在澆筑工況下，應(yīng)控制澆筑速度，保溫連接件間距不宜大于 400mm，可有效避免預(yù)制板開裂。 最后基于研究成果提出了相應(yīng)的優(yōu)化建議，為未來雙面疊合夾心保溫剪力墻體系的研究和應(yīng)用提供參考依據(jù)。

Abstract: The system development and structural overview of the double composite sandwich shear wall were introduced， andthe double composite sandwich shear wall was systematically analyzed from the aspects of the selection of thermal insulationconnectors， the load and the stress state. In addition， the seismic performance， temperature performance and pouringcondition performance of double composite sandwich shear wall were systematically tested and studied. The test results showthat the main seismic performance indicators such as bearing capacity， displacement ductility， deformation capacity， andenergy dissipation capacity of the double composite sandwich shear wall are similar to those of the cast￣in￣place comparisonspecimen， and the seismic performance is excellent， which can realize achieve the same cast￣in￣place design. Under theaction of temperature， the thermal insulation connector is subjected to a large force and can meet the bearing capacityrequirements. Under the pouring conditions， the pouring speed should be controlled， and the distance between the thermalinsulation connectors should not be greater than 400mm， which can effectively avoid the cracking of the prefabricated plate.Finally， the corresponding optimization suggestions were put forward based on the research results， which provides a referencefor the research and application of the double composite sandwich shear wall system in the future.

Keywords: double composite sandwich shear wall； thermal insulation connector； seismic performance； temperatureperformance； pouring condition
