  The Integral-Abutment Bridge (IAB) concept was developed at least as far back as the 1930s to solve longterm structural problems that can occur with conventional bridge designs. Due to limited funding sources for bridge maintenance, it is desirable to establish strategies for eliminating joints as much as possible and converting/retrofitting bridges with troublesome joints to jointless design. IABs or jointless bridges have many advantages over full height abutment or stub abutment bridges. They eliminate expansion joints in bridge superstructures. They also simplify design, detailing, and construction. In spite of many of these recognized benefits, the behavior of such structures is not yet fully understood, and nationally adopted design criteria are still lacking. This paper presents results of finite element analysis of four IABs at Kassala State (Sudan), the four bridges are consi.. Read More»
