摘　　要：铅板是一种耗能能力良好,具有较强的变形能力、抗剪切能力,且制作简易方便的装置.本文对梁端布置不同厚度的铅板耗能情况进行有限元分析,比较不同厚度的铅板对框架结构梁柱节点的抗震性能影响.结果表明,铅板布置于梁端对结构抗耗能能力有较大提高.The plumbum plates as a kind of materials with well energy dissipation and deformation abilities, has al- ready used in many projects. Its strong abilities of shearing strength make it much easier to product. In this article, the author compared with hysteretic loops of different beam which are arranged plumbum plates with different thick- ness at plastic hinges area, in order to draw a conclusion in anti - seismic abilities of different beams. The analysis shows that the plumbum plates with different thickness arranged at plastic hinges area make a strong influence in antiseismic abilities of the beam.
