一、有限单元法分析模型 本文为了用有限单元法分析钢筋混凝土构件的裂缝宽度,按下述模型编制了平面问题的非线性分析程序。 该程序把混凝土离散为三角形单元,纲筋离散成线形单元,在纵向钢筋与混凝土间引入模拟粘结力的联结单元,联结单元的型式如图1所示。混凝土裂缝穿过单元本

First, the finite element method analysis model In order to use the finite element method to analyze the crack width of reinforced concrete components, according to the following model to prepare a nonlinear analysis program of the plane problem. The program discretes the concrete into triangular elements, and the reinforcements are discretized into linear elements. The coupling elements that simulate the adhesion force are introduced between the longitudinal reinforcement and the concrete. The type of the coupling element is shown in Fig. 1.
