摘要
通过空间杆系有限元程序,对1座125 m跨径的异型人行钢箱梁桥进行了力学分析,分析了该结构的受力特点。根据分析结果确定其内力控制截面,采用大型水袋模拟人群集度的加载方式,对其进行了静载试验研究,试验结果与理论计算结果吻合较好,表明该桥的受力性能较好。
Using a space miss finite element program, the author conducts mechanics analysis of a 125 m span special - Shaped steel box beam footbridge and of its loading features. Then the author defines its control force section and imitates the loading method of dense population adopting huge water bags to make a static load test. The experiment result is in accordance with the theoretical calculations, which indicates that the mechanical performance of this bridge is good.
