建立了一个钢筋混凝土T梁模型,对一个支座施加了X方向和Y方向的约束,对另一个支座施加了Y方向的约束,用得是SOLID65单元,LINK8单元,PLANE42单元。
施加完荷载,查看变形图,然后弹出了一个错误窗口。错误提示信息如下:
The value of UX at node 49 is 6.088812313E+09. It is greater than the current limit of 1000000. This generally indicates rigid body motion as a result of an unconstrained model. Verify that your model is properly constrained. 难道约束不对吗,请高手指点 |
