Abstract: The l#gate of Hainan Yangpu Economic Development was made by prestressed cable and space truss structure for cable-supported structure. According to the overall structure of working together on the structure analysis, some measures are taken to exert their effects, such as steel column using one-wey rotating support, setting resist wind cable to guarantee the main cable to work, etc.
Keywords: prestressed cable-supported structure; space truss structure; non-linear analysis; one-way rotating support
