摘要
Abstract
By taking a three-tower suspension bridge--Taizhou Highway Bridge over Yangtze River with main span of 1 080 m as example, by using 3D structural nonlinear aerostatic analysis, the influence of deck erection sequence on the aerostatic stability during the whole construction process is revealed, and the favorable deck erection sequence is also proposed with respect to the aerostatic stability.The resuhs show that good aerostatic stability can be obtained for threetower suspension bridges as the deck erection starts simultaneously from the pylons to the midpoints of main spans.关键词
