摘　　要：为了研究波型法兰节点的抗震性能,首先阐述了基于结构抗震性能化的抗震设计方法以及采用滞回曲线衡量法兰节点耗能的思路;然后,通过有限元模拟的方法分别对普通平焊带颈法兰和新型波型法兰节点施加低周反复水平荷载,进行动力荷载的受力分析;最后,通过分析比较得出,新型波型法兰节点具有更好的抗震性能。In order to study the seismic performance of wave-neck flange joints, this paper expounds the seismic design method based on the seismic performance of structure and the thought that use hysteresis curve to measure the energy consumption of flange joints firstly. Then, through the finite element simulation method,low horizontal loads are applied for forging high-neck flange and wave-neck flange respectively, and the stress analysis for power load is conducted. Finally,through analysis and comparison, it is found that the wave-neck flange has good seismic performance.
