【摘要】 目的为了研究内置钢板的钢筋混凝土连梁与混凝土剪力墙的组合节点的抗震性能.方法进行了3个连梁与剪力墙节点试件在竖向低周往复荷载作用下的试验.结果内置钢板连梁与剪力墙节点比普通钢筋混凝土连梁与剪力墙节点在承载力、变形性能、延性与耗能能力等方面有显著提高;连梁开裂破坏并形成塑性铰后,随着荷载的增大,塑性铰附近的钢板开始进入屈服状态;焊接在钢板上栓钉的布置方式对节点的承载能力和耗能能力有很大影响,对节点的变形能力影响不是很大.结论内置钢板的钢筋混凝土连梁与混凝土剪力墙的组合节点具有良好的抗震性能,此节点形式具有良好的应用和发展前景.更多还原

【Abstract】 The paper is researching of seismic performance of the built-in steel plate reinforced concrete coupling beams to reinforced concrete shear wall joint.The tests of the three group beams and shear walls joint specimens under the low cyclic vertical loading are completed.The test results show that:the built-in steel plate reinforced concrete coupling beams to reinforced concrete shear wall joint are improved significantly compared to ordinary reinforced concrete beams to shear wall joint in the bearing capacity,deformation properties,ductility and energy dissipation capacity.After beam cracking damage and the formation of plastic hinges are appeared,as the load increases,steel plate attached to the plastic hinge began to enter the yield state;The layout of steel stud welded on steel plate has great influence in bearing capacity and energy dissipation capacity,and the influnence for the deformation of the joint is not great.The bearing capacity,deformation and energy dissipation properties of the joints of built-in steel plate reinforced concrete coupling beams and concrete shear walls are obviously better than the joints of traditionally reinforced concrete coupling beams and concrete shear walls.So this kind of joints which was suggested in this paper have good prospects of application and development.更多还原
