摘要:

为了满足预制型钢混凝土边框柱钢板剪力墙(SPSW)连接节点的承载能力和变形要求,设计了法兰板-螺栓连接的新型预制型钢混凝土柱-钢板混凝土节点,分别建立预制和现浇节点的有限元模型,对比二者在同一荷载条件下的承载性能,并分析改变混凝土强度等级、内置钢板强度等级与厚度、法兰板厚度、轴压比和螺栓数量等参数对连接节点承载能力及变形的影响.结果表明,预制节点和现浇节点的受力性能相似,增加混凝土强度等级、螺栓数量和法兰板厚度均能够提高节点的承载能力,改变内置钢板强度等级与厚度对于节点力学性能影响并不大.设计时建议采用34个螺栓,20 mm厚的内置钢板,15 mm厚的法兰板,轴压比控制在0.7左右.

Abstract:

In order to meet the bearing capacity and deformation requirements of the joint between the prefabricated steel reinforced concrete frame column and the steel plate shear wall (SPSW), the new flange-bolt connection mode were designed and applied between the prefabricated steel reinforced concrete column and the steel plate shear wall. The flange-bolt connection mode was established the finite element model of the prefabricated and cast-in-place joints respectively, and the bearing performance of the two joints under the same load condition was compared. The effects of concrete strength grade, strength grade and thickness of built-in steel plate, thickness of flange plate, axial compression ratio and number of bolts on the bearing capacity and deformation capacity of the connected joint were analyzed. The results show that the mechanical properties of the prefabricated joints are similar to those of the cast-in-place joints. Increasing the concrete strength grade, the number of bolts and the thickness of the flange plate can improve the bearing capacity of the joints, while changing the strength grade of the built-in steel plate has little effect on the mechanical properties of the joints. It is recommended to use 34 bolts, 20 mm thick built-in steel plate, 15 mm thick flange, and the axial compression ratio is controlled at about 0.7.

Key words: steel plate shear wall (SPSW), prefabricated steel reinforced concrete, flange-bolt connection, finite element analysis, bearing capacity
