插接连接单管钢塔中塔身插接节点的受力性能和传力机理比较复杂,属于接触问题,其对于塔体整体抗弯性能的影响还不十分清楚,各国的规范中也尚无关于插接节点的计算要求。本文以接触有限元理论为基础对插接节点的抗弯刚度进行了研究。
The mechanical behavior and force transmission mechanism of the tower connector in the single-pipe steel tower are more complicated and belong to the contact problem, and the influence on the whole bending performance of the tower body is not yet clear enough. Calculation requirements of the patch node. In this paper, based on the contact finite element theory, the flexural rigidity of the joints is studied.
