Rearch on Design of Aluminum Truss Bridge

Abstract

In recent years aluminum bridges have been constructed in China, but lack of aluminum design and construction standards limits its development. Traditional design theory of concrete and steel can’t be completely adopted for its application in bearing structures. In order to solve technical difficulty, material type, deflection under live load, frequency and bucking of aluminum bridges are analyzed based on aluminum half-opened truss bridges constructed in China. Compared with related design standards at home and abroad, recommendations are put forward to provide theoretical basis for further application and research of aluminum truss bridges.
