| Abstract: | A new type of structural system named as single-layer folded-plane latticed shell structure was adopted for the steel roof of the main stadium of the Shenzhen Universiade Sports Center.The whole structure was composed of numerous triangle grids bent in different angles with subordinate triangle grids inside.The subordinate triangle grids were connected to the quarter point of the intersecting line of two surfaces by the subordinate bar of the welded combined box section.The stability of the major bar in the... |
