摘要
介绍了一种可用于多、高层房屋建筑的新型装配整体式RC结构体系——外壳预制核心现浇装配整体式RC结构,进行了该结构体系的RC梁的预制U形外壳的抗弯承载力试验,考察了装配整体式U形外壳的破坏模式、开裂荷载、极限承载力等力学性能及其计算方法,为实际工程应用提供了参考。
A new type fabricated integral structure with precast shell and cast-in-place core concrete is introduced in this paper. Tests on bending-resistance of concrete U-shaped shell are carried out, and these failure modes, cracking load, ultimate bearing capacity are investigated. Besides ,the calculating method of cracking strength is provided. The results can be referred for engineering application.
