摘    要:Conical membrane structures as a typical form arewidely used in engineering practice. For example, theShanghai Stadium, Weihai Stadium in China and theRiyadh Stadium in Saudi Arabia are all composed of afew conical membrane structures. This form of mem-brane structure is characterized by a high point in themiddle and low supporting edges around the border,like a cone.The edge elements of the conical membrane struc-ture may be rigid beams or flexible cables supported byseparate columns or b…

关 键 词:风感应响应  圆锥隔膜结构  动态系数  参数分析

Abstract:Conical membrane structures are a typical form of tensile membrane structures. In the past, most studies focused on the static performance, but few on dynamic performance. In this paper, systematic parameter analysis of wind-induced response of conical membrane structures has been performed with nonlinear random simulation method in a time domain, by considering some parameters, such as span, rise-span ratio, prestress of membrane, and characteristic of the approaching wind flow. Moreover, formulas of the dynamic coefficient and nonlinear adjustment factor are advised, which can be conveniently used in wind-resistant design of conical membrane structures.
Keywords:conical membrane structures  wind-induced response  the dynamic coefficient  nonlinear adjustment factor
