钢筋混凝土简支桥梁局部空间非线性地震反应分析

An Analysis of the Three Dimensional Partial Nonlinear Seismic Response of Reinforced Concrete Bridges

本文用横隔板材料的单轴本构关系对跨度为32m的预应力混凝土简支桥梁进行了空间局部非线性地震反应分析,研究了在考虑横隔板的非线性之后该桥的受力状态,探讨了支座上跳的可能性和横隔板的受力破坏特点。

In this paper, the three dimensional partial nonlinear seismic resopnse of 32m prestressed reinforced concrete bridges is analysed. The behavior of stresses in structure when an earthquake occures is discussed. The jumping possibility of the supports and the destroying features of transvserse diaphragm plate due to nonlinearity are also investigated.
