摘要
从解决桥梁结构的实际问题出发,根据桥梁结构的抗震能力及计力法的需要,由于强度折减系数R与延性系数μ的关系建立弹塑性反应谱的原理,建立了基于《公路工程抗震设计规范》(JTJ 004-89)给出的弹性反应谱的非弹性地震需求谱,为桥梁结构抗震性能评价的研究提供参考意见。
In this paper, the capacity design method of bridge structure is introduced, and based on the principles of the inelastic spectrum established by using the relationship between the force reduction factor R and ductility factor μ, the seismic demand spectra are obtained from the desing spectrum of the Road Engineering Seismic DesignCode（JTJ 004-89）. This will be beneficial to the earthquake-resistant capacity design in practical bridge structures.
