The experimental research on seismic performance for angles beam - column connections of steel frame 钢框架梁柱角钢节点连接的抗震性能试验研究
The seismic resistant design method of reinforced concrete beam - column connections based on compression strut and softened truss models 基于压杆和软化桁架模型的钢砼梁柱节点抗震设计方法
In the northridge earthquake in 1994 and the kobe earthquake in 1995 , widespread and unpredicted brittle fractures were found in weld steel beam - column connections ( weld - flange - bolted - web connections ) 在1994年美国北岭地震和1995年日本阪神地震中,发生了大量钢框架梁柱节点的脆性破坏。
Depending upon stiffness and strength requirements , this transfer of bending moments can be achieved by either semi - rigid or rigid beam - column connections . in both case , the intersection between beams and columns ( the beam - column joint ) will be subjected to high shears 本文从节点域的屈服过程,破坏机理入手,采用虚功原理,对节点域屈曲进行了推演,得到了节点域破坏的最大剪力,以及屈服后所能承受的剪力。
The stiffness , strength and behavior of different kinds of beam - column connections were investigated . finite element analyses were used to study fracture toughness in welded beam - column connections . the influence of concrete slabs on behavior of beam - column connections was also investigated 地震荷载作用与静力荷载作用相比,构件、节点和整个体系的刚度并没有多大变化,因此本课题首先研究静力荷载作用下梁柱节点的刚度,建立节点模型。
