摘要
用有限元软件ANSYS对一简支组合梁进行材料非线性的计算和分析,计算中混凝土除具有非线性的本构关系外,还通过破坏准则考虑了混凝土的开裂和压坏等特性。计算得到的承载力与按求塑性极限承载力的方法计算的吻合较好,这为今后进一步研究组合梁的受力特性奠定了基础。
The paper introduces the calculation and analysis of a steel concrete composite beam with Program ANSYS. Besides the non - linear strain - stress relation, the failure criteria of concrete was used to account for the craze and crush of the concrete. The computed ultimate loading has a good agreement with that calculated according to ultimate load design. Therefore a precondition for further studding load bearing behaviors of composite beam is existed.
