摘要
以钢筋-混凝土的拉拔实验的有限元分析为例,介绍了ANSYS有限元软件中的3种接触分析:点-面、点-点、面-面接触;详细描述了接触分析建模的过程及注意事项;最后利用面-面接触单元建立了钢筋与混凝土的拉拔实验的有限元分析模型.进行了相关力学分析,求出钢筋在混凝土中的滑移量及锚固长度,并与规范中的相关数据作比较.结果表明,实验结果与理论值相吻合,证明ANSYS软件能方便地用于钢筋与混凝土间的滑移分析.
The paper introduced contact analysis of ANSYS including node to surface, node to node and surface to surface contacts through an example of finite element analysis of drawing-test of concrete and bar. And the modet construction process of contact analysis was specified. The finite element contact analysis model of drawing-test of concrete and bar is constructed with surface to surface contact element. Anchorage length is solved by ANSYS and compared with value solved by Code for design of concrete structures. The sliding-result of ANSYS is coincident with the theoretical analysis and test. The result demonstrates that software of ANSYS is a good tool for sliding analysis of steel-concrete.
