Structure Optimization and Construction Technology Analysis of the Tower-girder Consolidation Area of a Cable-stayed Bridge with Spatial Twist-cable Plane and Curved Tower
The finite element analysis of the local modeling of the tower-girder consolidation area of a cable-stayed bridge with spatial twist-cable plane and curved tower is carried out in order to solve load selection and constraints problem when the detail scale of the complex joint areais cut off.The local stress concentration problem which can have serious implications to structural safety,has been solved by optimizing structural design and decreasing the stress on the consolidation area.Using less support structure for lifting and installation on each reasonable construction section is defined as the key construction technology based on the analysis of structure optimization of the consolidation area.
