Static Performance Analysis of the Drum-Shaped Honeycomb-Type Ⅲ Cable Dome with Quad-Strut Layout
摘要
Abstract
The drum-shaped honeycomb-type Ⅲ cable dome is the most versatile type of cable dome structure in terms of configuration,as the multi-strut concept is adopted instead of the traditional concept.In order to study the static performance of the new drum-shaped honeycomb-type Ⅲ cable dome structure,a 120 m span finite element model was established to study the deformation and internal force of the structure under different loadings and distribution methods.Further parametric analysis was carried out to the structure,with the selected parameters including initial prestress level,rise-to-span ratio,strut height(thickness-to-span ratio)and lower chord node arrangement scheme.The effect of the various parameters on the static performance of the structure was assessed,including the overall stiffness and load bearing capacity of the structure.The results show that the drum-shaped honeycomb-type cable dome has a good structural performance,each cable rod is not prone to damage,and the overall structural stiffness is large.The reasonable range of values including the initial stress level and relevant geometric parameters is given,which provides a reference for the practical engineering design and application of cable dome.关键词
