本文利用结构的对称性,对西安市五路口封闭圆环形钢箱梁人行天桥的平台与跑梯,按半结构采用SAP84程序三维框架单元进行计算,论证了结构的可靠性,指出结构在强度和刚度方面均具有较大的安全储备。
In this paper, the symmetry of the structure is used to calculate the structure and reliability of the platform and run-up ladder of the closed circular steel box girder pedestrian bridge at Wulu intersection in Xi’an according to the semi-structure using the SAP84 program. The reliability of the structure is demonstrated. And rigidity have a greater safety reserves.
