| 摘 要： | 非节点连接方法为加筋结构提供了筋与混凝土可完全独立的单元建模方案,允许筋单元与混凝土单元交错划分。针对该方法中筋单元跨越多个混凝土单元的情况,分析了钢筋单元与混凝土单元面的交点位置关系及其影响效果,建立了在混凝土单元交界面划分筋单元节点的数学模型,解决了钢筋单元与混凝土单元的位移协调问题,通过算例演示了本文方法的可行性和有效性。

| Abstract: | The non-node connectivity method provides a completely independent element modeling program for steel and concrete in reinforced structure,it allows steel element and concrete element division staggered. To the issue of steel element crossing through the concrete element in this method,the intersection location relationship between steel element and concrete element surfacse and its effect are analyzed. The mathematics model which devides the nodes of steel elements at the intersection of concrete element i... |
