( Technical Center of Shanghai Xian Dai Architectural Design( Croup) Co. ,Ltd. Shanghai 200041, China)Abstract: Parameter analysis is studied on beam string structure including rise of arc, drop of cable, prestress of cable, number of stay bars, stiffness of up truss and arrangement of stay bars in this article. Effect of these 6 parameters on mechanical property of the structure is obtained. The results can be used as reference for designing this kind of structure.
Keywords: beam string structure; rise of arc; drop of cable; prestress; stay bar arrangement
