| 摘 要： | 为了对钢管混凝土拱桥的抗震性能进行更加深入的了解,提出基于“统一理论”的钢管混凝土拱桥弹塑性地震响应分析方法。首先利用钢管混凝土构件“统一理论”双线性力-变形关系,运用集中塑性铰模型,建立了钢管混凝土构件梁柱单元,在此基础上开发一钢管混凝土拱桥弹塑性地震响应分析程序。使用DRAIN-2D和笔者开发的程序共同对一单拱模型进行计算,验证了程序的正确性。

| Abstract: | In order to have a further study on the seismic behavior of concrete-filled-steel-tube (CFST) arch bridges,a elasto-plastic seismic response analytical method is presented herein based on the unified theory. A beam-column element for CFST component is firstly developed by using lumped plastic hinge model with bilinear force-displacement relationship based on unified theory, a elasto-plastic seismic response analytical program is then developed and is verified with a single arch model by DRAIN-2D program. |
