Study on Scheme Design of New Y-shaped Girder Long-span Bridge
Y-shaped girder is generally used for small-span pedestrian bridges.But in practical projects,it is sometimes necessary to build a long-span vehicular bridge with Y-shaped girder and unconditional piers at the intersection of each branch of the main girder.In order to meet the requirements of the above conditions,a new type of new Y-shaped girder long-span bridge structure system with combined forces of"strut and girder"is proposed.By analyzing the force transmission mechanism of the structure system,the design scheme and stress situation of a bridge project with this structure are introduced.At the same time,the finite element program is used to analyze and summarize the internal force and reaction change law of the structural system with the change of the horizontal angle of the girder,which provides a useful reference for bridge design under similar construction conditions.
