Abstract
For complicated stress condition of the main beam of cable stayed bridge, the initial structure dimension is commonly determined according to experience in design and the relatively optimum structure that satisfies the requirement is obtained through several calculations. In this paper, combined with Junshan Yangtze River cable stayed bridge project, through analyzing singular problems of traditional evolutionary structural topological optimization, the bi-directional evolutionary structural optimization that can ensure convergence is advanced. Thus the topological optimization of beam cross section of cable stayed bridge is studied.关键词
