拱桥成桥状态下吊杆索力优化
Completed bridge suspender forces optimization of a arch bridge
摘要
Abstract
One of the standards which measures the arch and rigid frame is to check the internal force distribution and size under the finished state. When the bending stress of the arch rib and the main girder under the action of constant and live load is small and well-distributed, the bridge can be regarded as reasonable. The method and theory of cable force optimization mainly takes cable-stayed bridge as the object of research. The cable optimization model and the constrained expression were constructed on the basis of cable-stayed bridge's cable force optimization and constrained energy minimization method. The cable force optimization of arch bridge's completion state was also studied with reference to engineering practices in this paper.关键词
