摘要
本文应用有限单元法分析具有完全或非完全相互作用的钢-混凝土组合梁若干问题。构造了一种由偏心板单元和偏心连接单元组成的混合有限元模型。本文以模型试验及其它理论结果为例,证明了该单元的有效性及可靠性。最后,对组合梁进行大量分析,解释了一些实验现象和实验中无法解决的问题。
In this paper a finite-element method is used to analyse a number of problems of the steel-concrete composite beams with complete or incomplete interaction A mixed finite elment model is constructed, which is made up by the eccentric plate element and the eccentric linkage element. The efficieacy and reliability of the finite element is proved, and the difficult problems produced in the experiments are solved.
