摘要:
为研究钢框架-装配式混凝土抗侧力墙板装配式结构体系的受力性能,对4榀钢框架-预制混凝土抗侧力墙板结构足尺试件进行低周反复荷载作用下的试验研究,测试连接构造的可靠性,研究结构的破坏机理、滞回性能、延性及变形和耗能性能等.采用有限元软件ABAQUS对试验模型进行分析,并在验证有限元模型可靠性的基础上,研究抗侧力墙板与钢梁连接界面的受力性能和传力机理,考察各类连接件承担剪力和弯矩的分布情况以及分配关系.试验结果表明:该结构体系为一种典型的双重抗侧力体系,加载过程呈现出明显的两阶段性,抗侧力墙板先于钢框架破坏,为结构体系的第1道防线;型钢混凝土墙板与钢梁连接界面上的剪力由型钢与抗剪栓钉共同承担,对于钢筋混凝土墙板,剪力作用主要由抗剪栓钉承担;连接界面上的弯矩作用主要通过型钢(或锚筋)承担拉、压力和混凝土承压来平衡.
Abstract:
In order to research the mechanical behavior of steel frame-fabricated concrete lateral force resisting wall structures, four full scale specimens were tested with cyclic horizontal loads. The reliability, failure mode, hysteretic behavior, ductility, deformation, and energy dissipation of the fabricated structures were investigated. The finite element software ABAQUS was used to analyze the experimental model.The mechanical behavior and the force transfer mechanism of the connection interface between the lateral force resisting wall and the steel beam were analyzed based on the reliability of the finite element model. The distribution and relationship of the shear force and the bending moment shared by all kinds of connectors were investigated. The experimental results show that the structure is a kind of typical double lateral force resisting systems. The loading process presents obvious two stages. The concrete lateral force resisting wall is destroyed before the steel frame and regarded as the first line of defense for the structural system. The shear force in the connection interface between the steel concrete lateral force resisting wall and the steel beam is shared by the shape steel and the stud, and the shear force is mainly shared by the stud for the concrete lateral force resisting wall. The bending moment in the connection interface is balanced by the tensile and the compressive force shared by shape steel or anchor bar and the compressive force shared by concrete.
