Abstract
Currently, the commonly built suspension bridges are single or three-span symmetric structural system. To well suit with the natural conditions, several two-span non-symmetric suspension bridges have been built such as the Tsingma Bridge in Hongkong, the Xihoumen Bridge in China etc. It is well known that the wind stability of suspension bridges during erection becomes a subject of major concern. Up to now, comprehensive investigations on the wind stability of structurally symmetric suspension bridges under erection have been conducted, and some wind stability improvement measures have been proposed. (Cobo del Arco and Aparicio 2001, Ge and Tanaka 2000, Zhang 2004). Unfortunately, few investigations on the wind stability of structurally non-symmetric suspension bridge during erection have been done. The present paper focuses its attention on how the wind stability varies during deck erection, and also attempts to find an optimized erection sequence for a structurally non-symmetric suspension bridge.
