Abstract

The embodiment of the invention discloses an installation method of a stay cable of a cable-stayed bridge reduced-scale test model. The method comprises the steps of building a cable-stayed bridge reduced-scale finite element model and a stay-cable-free cable-stayed bridge reduced-scale test model according to the bridge parameters; obtaining the cable force tension value of each stay cable in a cable-stayed bridge according to the bridge forming state requirement of the cable-stayed bridge and the reduced-scale finite element model of the cable-stayed bridge; and installing the stay cables according to the cable-stayed bridge reduced scale test model without the stay cable and the cable force tension values. The method is not limited to a single expected value, different design requirements can be met, the calculation process is concise and clear, the tensioning steps are clear, only the tension information of one cable needs to be paid attention to each time of tensioning, and the complex step that overall optimization cable adjustment is conducted after all stay cables are tensioned, is avoided.

Description

technical field [0001] The invention relates to the installation field of cable-stayed cables, in particular to a method for installing cable-stayed cables of a scaled-down test model of a cable-stayed bridge. Background technique [0002] A cable-stayed bridge is a bridge in which the main girder is directly pulled on the bridge tower by many cables. Modern cable-stayed bridges occupy an important position in modern bridge structures because of their large spanning capacity, good technical and economic indicators and aesthetic value. The cable-stayed bridge is an important load-bearing component of the cable-stayed bridge, which is responsible for transferring the load of the main girder to the bridge tower. Whether the force value of the cable-stayed cable is properly set will affect the accuracy of the scaled-scale test model of the cable-stayed bridge. [0003] At present, in the modeling of cable-stayed bridge scale model, the tensioning methods of cable force include ...
