摘要
节点域的厚度直接影响着节点的刚度、强度和变形 ,从而影响框架的抗震性能。在罕遇地震下 ,要求钢框架能够抵抗比多遇地震下大得多的变形。这种变形一般是非弹性的 ,其大小取决于框架中每个组成部分的相对强度和刚度。如果节点域的厚度取得合适 ,则既能够参与耗散能量 ,又不致使钢框架产生过大的层间变形。对计算节点域厚度的各种方法进行了比较 ,并就节点域板剪切变形的计算方法进行了探讨。
The thickness of a panel zone has a direct influence on the stiffness,strength and deformation steel moment resisting frame,by which the aseismic performance of a frame is also affected.A steel frame must resist large deformation from rarely happened large earthquake than those from usual ones.These deformations are nonelastic, depending on the relative strength and stiffness of each component of the frame.A panel zone with a proper thickness can not only participate in energy dissipation,but also make the frame produce moderate horizontal deformation.The methods of computing the thickness of the panel zone are compared and the calculation methods of shear deformation of a panel zone are also provided.
