Numerical Investigation on the Behavior of Skewed Concrete Tied Arch Bridges
Abstract Tied arch bridges, among other types of arch bridges, are the most delightful bridges that have been ever shaped on the earth. Analysis and design of tied arch bridge is further intricate especially when the bridge is skewed. In this research paper, the behavior of skewed concrete tied arch bridge is presented. Numerical investigation through three-dimensional finite element models was performed to examine the behavior of skewed concrete tied arch bridge. The study involved five concrete tied arch bridges with five different span lengths of 30, 35, 40, 45, and 50 m, and different skew angles ranging from 0°-to-60°. Linear static analysis was conducted for the nominated bridges. The effect of skew angle, and the aspect ratio (span length/width), on the response of the global and the main supporting structural elements and on the deck flooring system of the bridge was examined. The results showed that an increase of the skew angle will alter the bridge behavior. Deflections, reactions, and straining actions of the main supporting elements and floor system were significantly influenced when the skew angle increased.
