摘要
根据钢框架强节点弱构件的抗震设计原则,以两种方式对树状柱梁柱节点进行加强,然后用三维有限元模拟分析,并进行对比。ANSYS模拟结果表明,采用这两种形式能将塑性铰从梁柱节点外移,大大缓解节点的应力状态,提高结构的抗震性能。
According to the principles of strong node but weak member in the anti-seismic design of steel frames, two methods are used to reinforce the column-tree moment-resisting and beam-to-column connections, then the 3D finite element method is adopted, and the reinforced node form is compared with the traditional connections. ANSYS model shows that the reinforced node form can make the plastic-hinge move away from the beam-to-column connection, greatly reducing the possibility of fragility damage of the weld and improving the seismic resistance of the structure.
