Book Description
The thesis investigates the effect of skewness on reinforced concrete solid slab bridges. This study considers bridge decks with various angles of skewness, and live load distribution from truck loading on the solid slab is determined. Simple multi-lane bridges are analyzed for a variety of span lengths and slab widths. The loading consists of AASHTO HS-20 design truck, which is so positioned laterally and longitudinally to produce maximum moments in the slab. The analysis is performed using the finite element method and a proper mesh is selected to account for the skewness of the bridge slab. Finally, the behavior of the bridges analyzed is assessed with design procedure currently in use. The American Association of State Highway and Transportation Officials (AASHTO), "Standard Specifications for Highway Bridges, 1996". Also, a comparison between straight and skewed bridges is conducted.
