Cost-Effective Concrete Box Culvert Design
The investigation examined the provisions of the American Association of State Highway and Transportation Officials (AASHTO) 1983 Standard Specifications for Highway Bridges, relative to design of reinforced concrete box culverts (RCB). Three major areas were studied: (1) soil pressures, (2) live loads, and (3) design methods. The soil pressure analysis was performed by computer finite element modeling, taking into account soil-structure interaction. The AASHTO provisions for wheel loads, or live loading, were analyzed using Boussinesq's theory and influence surface techniques. Finally, it was found that the ultimate strength design approach was superior to the working stress design method. In addition to providing a uniform safety margin against failure throughout the culvert, it can result in significant material savings.
