摘要:
为了分析结构在地震作用下的弹塑性反应,该文探讨了弹塑性反应谱。该文推导了弹 塑性反应谱的基本方程,计算了等延性强度需求谱; 描述了通过强度折减系数、延性系数及结构 周期之间的关系建立弹塑性反应谱的方法; 参照弹性反应谱理论分别得到了四种弹塑性反应 谱。计算结果表明: 当延性系数较小且土质较硬时,该文计算的弹塑性反应谱与范立础的弹塑 性反应谱近似相等; 当延性系数较大且土质柔软时,该文计算的弹塑性反应谱相对安全。
Abstract:
In order to analyse the elasto-plastic response of structure under the seismic action, this paper studies an elasto-plastic response spectrum. The basic equation of an elasto-plastic response spectrum is established and the constant-ductility strength demand spectra are calculated. The methods of elasto-plastic spectra established by relationship among the strength reducing coefficients and the ductility coefficients as well as the structural periods are described. Four kinds of elasto-plastic response spectra are deduced from referring to the elastic response spectrum. The calculation result shows that the elasto-plastic response spectra proposed here are similar to Fan Lichu’s elasto-plastic response spectra under the condition of hard soil and small ductility coefficient,and the elasto-plastic response spectra proposed here are relatively safe under the condition of soft soil and large ductility coefficient.
