Numerical Simulation of Partial-Depth Precast Concrete Bridge Deck Spalling
This paper describes the results of numerical simulations performed to investigate the spalling mechanism observed in several partial-depth precast prestressed concrete (PPC) bridge decks. Corrosion-induced cracking of prestressed steel reinforcement and panel butting were modeled using 2D finite element analysis to examine the nature of crack propagation that triggers the spalling effect observed. A parametric study was carried out on the basis of field observations from several bridges. FEM results showed that spalling is sensitive to side and bottom cover, and spacing of reinforcement attributable to bridging cracks. Findings indicate that the spalling mechanism is triggered by the presence of a critical bridging crack.
