【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。更多还原

【Abstract】 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 Design Code(JTJ 004-89).This will be beneficial to the earthquake-resistant capacity design in practical bridge structures.更多还原
