桥梁结构徐变次内力分析

Analysis of Concrete Bridges for Secondary Inner Force of Creep

本文应用初应变法和能量原理来分析桥梁结构的徐变次内力,导出位移法的单元刚度矩阵及荷载列阵,并论述了结构在各种施工情况下的徐变效应。

The analytical method of concrete bridges for the creeping Secondary inner force of creep has been described in this paper on the basis of the initial strain method and the principle of energy. The stiffness matrix and the force vector of the displacement method are derived, and the creeping effects of the structure under different construction conditions are presented and discussed.
