Wind-induced response analysis of conical membrane structures

摘要

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.
