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.
In order to study the mechanical performance of the steel frame-assembled concrete anti-skid panel assembly type structure system, the experimental study of 4 × 10-ft steel frame-prestressed concrete structure , To test the reliability of the connection structure, to study the failure mechanism of the structure, hysteretic performance, ductility and deformation and energy dissipation performance etc. The finite element software ABAQUS is used to analyze the experimental model and verify the reliability of the finite element model, The mechanical behavior and force transmission mechanism of the interface between the anti-sideboard and the steel beam are studied, and the distribution and the distribution of the shear forces and moments are investigated.The results show that the structure is a typical Double anti-lateral force system, the loading process showed a clear two-stage, anti-side force before the failure of the steel frame damage to the first line of the structural system of defense; steel reinforced concrete wall and steel beam interface at the shear force by For the reinforced concrete wallboard, the shearing force is mainly borne by the shear studs; the bending moment on the connection interface is mainly borned by the steel (or anchor bar), and the pressure and concrete Pressure to balance.
