地锚式悬索桥由主缆、加劲梁、桥塔、吊索、锚碇五部分组成,可以形成多种结构体系,如加劲梁采用不同的悬吊方式,那么不同悬吊结构体系也就具有不同的结构力学特性。为研究边扣对不同结构体系悬索桥受力的影响,以西堠门大桥为背景,采用桥梁非线性计算软件BNLAS建立计算模型,分别对两跨悬吊和三跨悬吊悬索桥的加劲梁在连续纵飘、纵向约束、纵竖向弹性约束以及简支体系下边扣对加劲梁受力和变形的影响进行了分析。
Ground anchor suspension bridge by the main cable, stiffening girder, pylons, slings, anchorage 碇 five parts, can form a variety of structural systems, such as stiffening girder using different suspension, then different suspension structure system will have different Structural mechanics. In order to study the influence of side buckle on the force of suspension bridge with different structural systems, the calculation model of the bridge non-linear calculation software BNLAS is established on the background of Xijianmen Bridge. Drift, longitudinal restraint, vertical and vertical elastic restraint, and the influence of the side buckle on the stress and deformation of stiffening girder under the simple supported system are analyzed.
