摘要：
A sufficient understanding of the mechanical performance of long-span triple-tower suspension bridge is essential for practical design as such bridge is significantly different from traditional suspension bridges because of the flexible middle tower. Accordingly, a parametric study of a triple-tower suspension bridge with main span of 2000 m is performed in this article. Based on finite-element analysis method, influences of several structural parameters on mechanical performance are investigated, including connection between tower and girder, ratio of beam height to span and beam width to span, which would provide reference and help for parameter selection in preliminary design.
