Ai Yong? Wang Bo2 Zheng Minli' (1.Construction Branch Panjin Vocational and Technical College Panjin Liaoning 124010 China;2.Dalian Branch of China Construction Eighth Engineering Division Co.Ltd.Dalian Liaoning 116021 China) Abstract:The roof of Panjin Sports Center Stadium is the large-span spatial tensioning cable-membrane structure whose maximum cantilevered length is 41m.The main cable system of roof includes an inner ring cable and radial cables which include 144 sling cables 72 dorsal cables and 72 valley cables. Membrane surface disposes in the annular area between the ring cable and the peripheral of steel frame and the front of membrane surface is level the back of membrane surface with horizontal direction exist angle.The entire membrane surface spatially warps and across 72 dorsal cables and 72 valley cables to form surface modeling.This paper descr...
