| 摘 要： | 预应力钢束在体单元作用时常转化为等效荷载,这时首先需要求出预应力筋与空间四面体单元交点。针对这一问题,提出了常见的预应力圆弧筋和直线筋与四面体单元求交算法,并通过实例验证本算法的准确性,供科研人员与设计人员参考。

| Abstract: | Prestressed steel cable is normally converted into equivalent load under the action of body element,and firstly intersection point of prestressed reinforcing steel and space tetrahedron element is required to be calculated.Based on this problem,intersection algorithm of common prestressed circular arc reinforcing steel and tetrahedron element is proposed and the accuracy of this algorithm is tested by example,providing references for scientific research personnel and designers. |
