FEM Analysis and Parameters Determination of Lightweight Concrete Multiple Shear Rivet Paving Project on Steel Box Girder Bridge Deck

The mechanical response of lightweight concrete multiple shear rivet pavement on the steel box girder bridge deck under wheel loading are analyzed by finite element method. Besides, the effects of various distance、diameter、height of shear rivet to pavement, are researched as well as the effects of thickness of lightweight concrete. Then some recommended parameters are put forward for the paving project.
