ABSTRACT
ABSTRACT: In this paper, some optimal and possible solutions of significant problems for a multi main-spans suspension bridge have been studied using a suspension bridge model with triple main-spans, each of 800 meter length. At first, advantages and disadvantages of multi main-spans suspension bridge are investigated by comparison with a single main-span suspension bridge of the same total length. After an overview of the basic characteristics, the effect of articulations, such as vertical supports of suspended deck at the towers and longitudinal connections, cable slippage resistance at the tower saddles and the deformation of suspended deck are presented followed by a study of constructability of cables and deck erections. Finally, issues of concern regarding safety and quality of construction are discussed and solutions are proposed.
