摘要
叠合梁跨中正截面承载力计算是叠合梁设计中最为重要而又尚未很好解决的一个问题 .通过对钢筋混凝土叠合梁进行非线性有限元计算 ,分析了叠合梁的基本受力性能及其应力重分布过程 。
The calculation of bearing capacity in the middle section of the beam is the most important problem in the design of concrete composite beam, and has not been solved well up to now. Discovery of the property and presentation of the mode on the moment transfusion of composite beams will provide theoretic basis for the design of composite beams. Through the nonlinear finite element analysis of cancrete composite beams, this paper analyzed the basic loading properties and stress redistribution process of composite beam, thus verified the existence of important mechanical property on the moment transfusion and the rationality of moment transfusion calculating mode.
