| Abstract: | PVA-ECC link slab of bridge deck is the section which located at the transverse connection joint of two spans or several spans of simple beam bridge.This paper analyzed the internal forces and deformations of link slab.The results show that the mechanical behaviors and deformations of PVA-ECC link slab meet requirements of highway standard.The cracks of the link slab are dense and uniform,better than the common concrete link slab. |
