Concrete Crack Control of Pile-to-Pilecap Connection in Integral Abutment Bridges under Cyclic Bridge Movement

Abstract:

Steel pile-concrete abutment connection in integral abutment bridges is vulnerable to cyclic bridge movement as well as seismic loads. Although this connection may determine the bridge strength and performance against the above loads, previous researches have merely focused on this connection. This study has investigated crack patterns using finite element analyses. The bridge movements were classified into three cases: (1) translation only; (2) rotation only; and (3) simultaneous translation and rotation. The identified cracks were diagonally occurred from the steel pile. PennDOT DM-4 reinforcement detail was hardly effective in controlling crack growing. This study also investigated spiral type reinforcement for the connection, and this type of reinforcement detail significantly improved the crack control capacity in integral abutment bridges.
