Abstract:The construction of integral abutment bridges (IABs), including semi-IABs, has increased substantially in the past two decades, partly because of reduced construction and maintenance costs. However, temperature-driven lateral movements, associated with the elimination of expansion joints, lead to a complex interaction between the bridge structure and the soils behind and under the abutment, which could result in soil densification, void formation, and settlement in the approach slab. The bridge's structure, ge… Show more
