Force Transfer Mechanism of the Hinge Joint of Multi-Adjacent Hollow Slab Precast Bridge

Abstract

For the common diseases of the hinge joint, a new structure named thin-film layer is presented to simulate its function in finite element model. Through the field test of an on-built bridge, real measured results are used to determine the parameters of the layer in the model. The model result shows that the deformations of the hinge joint include vertical shear dislocation and transverse bending deformation, which may lead to different kinds of diseases of the structure. A certain amount of reinforcements with reasonable configuration focusing on intensifying the whole structure is preferred.
