【摘要】：采用非线性有限元方法,对提出的一种新型钢梁-型钢混凝土剪力墙组合节点进行低周循环加载非线性研究,并通过参数化分析,探讨混凝土强度等级、混凝土保护层厚度、钢材强度等级、端板厚度和摩擦因数等因素对该类节点抗震性能的影响。结果表明:提出的这种新型盖板犬骨式钢梁-型钢混凝土剪力墙组合节点滞回曲线饱满,抗震性能优越;混凝土保护层厚度、钢材强度等级和端板厚度等因素对节点的抗震性能影响较大。
[Abstract]:Nonlinear finite element method is used to study the nonlinear loading of a new type of steel beam-steel concrete shear wall composite joint under low cycle cyclic loading. Through parametric analysis, the effects of concrete strength grade, concrete protective layer thickness, steel strength grade, end plate thickness and friction coefficient on the seismic performance of this kind of joint are discussed. The results show that the hysteretic curve of the new composite joint of canine steel beam and steel concrete shear wall is full and the seismic performance is superior, and the thickness of concrete protective layer, steel strength grade and end plate thickness have great influence on the seismic performance of the joint.
