The thermally induced cyclic loading on integral bridge abutments causes soil deformation and lateral stress ratcheting behind the abutment wall due to the expansion and contraction of the bridge deck. The forward and backward movements of the abutme

Integral bridges are a class of bridges with integral or semi-integral abutments, designed without expansion joints in the bridge deck of the superstructure. The significance of an integral bridge design is that it avoids durability and recurring mai

Integral bridges avoid many of the persistent issues with joint degradation and maintenance issues regularly experienced by traditional bridges. The cyclic thermal displacements of the integral bridge would be transferred by the joints to the abutmen

Abutment walls in integral abutment bridges (IABs) move in a cyclic pattern in response to temperature-induced expansion and/or contraction of the bridge superstructure. The repetitive abut...

This paper presents an efficient technique to calculate the passive earth pressure of a cohesionless sloping backfill on a rigid retaining wall which is an extension of the Terzaghi’s log-spiral approach. Moment equilibrium conditions are used to c

Integral Abutment Bridges are widely utilized around the world because they offer a design alternative minimizing the potential construction and maintenance difficulties associated with expansion joints in other types of bridges. However, integral br
