[摘要]為了保證雙面疊合剪力墻結構體系應用的安全性和可靠性,針對雙面疊合剪力墻結構的力學性能開展了深入的試驗研究,研究內(nèi)容包括雙面疊合剪力墻抗震性能、豎向連接鋼筋錨固性能以及整體結構抗震性能。對比了不同邊緣構件區(qū)構造、不同桁架筋間距離以及豎向連接鋼筋搭接長度是否增加500mm下雙面疊合剪力墻的抗震性能,分析了桁架筋和預制層對豎向連接鋼筋粘結強度的影響,以及深入探究了整體結構搭接連接影響區(qū)域的抗震性能。結果表明,合理設計下的雙面疊合剪力墻結構具有優(yōu)異的抗震性能,該結構體系可以進行廣泛應用。

Abstract:In order to ensure the safety and reliability of the application of double-faced superimposed shear wall structural system, in-depth experimental research was conducted on the mechanical performances of double-faced superimposed shear wall structure, and the research content included the seismic performance of double-faced superimposed shear wall, the anchoring performance of vertical connection reinforcement, and the seismic performance of the whole structure. The seismic performances of double-faced superimposed shear walls with different structural details were compared, including different boundary elements, different distances between reinforcement trusses and whether the lap length of vertical connecting reinforcement is increased by 500mm, and the influences of reinforcement truss and precast layer were analyzed on the bond strength of vertical connection reinforcement, and the seismic performance of the whole structure overlapping connection zone was deeply explored. The results show that the double-faced superimposed shear wall structure with reasonable design has excellent seismic performance and can be widely used.
Keywords:double-faced superimposed shear wall; seismic performance; bond strength; overlapping connection
