钢筋砼连续梁非线性有限元分析

Nonlinear Analysis of Reinforced Concrete Continuous Beams Using Finite Element Method

用有限元法对使用荷载下的钢筋砼连续梁做了非线性全过程分析。建立了矩形单元模式 ,用增量法对连续梁进行非线性分析。编制了计算程序 ,并对两根连续梁做了对比计算 。

The nonlinear analysis of reinforced concrete continuous beams under the service loads is per- formed by finite elementmethod.The rectangular elementis developed.The nonlinear analysis of continu- ous beams is performed using added loads method.A program is worked outand used to calculate two con- tinuous beams.The results of calculation are in good conformity with the corresponding testresults.
