摘要
轮辐式张拉结构自重轻、造型优美,同时能够和建筑功能及建筑造型完美结合,深受建筑师的喜爱。该结构体系源自于自行车轮辐条结构,内拉环和外压环通过径向索连接,形成自平衡受力体系。对轮辐式张拉结构的体系演变进行了研究,并分析了轮辐式张拉结构的力学特性和受力原理。根据受力形式将全封闭体系分为连贯一体型和叠合受力型。同时研究了全封闭轮辐式张拉结构体系可能实现的结构形式,并对各结构形式的受力性能进行了分析。
Wheel-spoke tension structure has the advantages of light weight,beautiful appearance,and also perfectly combines with architectural functions and shapes.This structural system is originated from bicycle spoke structure,and the inner and outer rings are connected by a radial cable to form a self-balanced force system.In this paper,the system of spoke structure evolution is studied,and the mechanical characteristics of wheel-spoke tension structure are analyzed.According to the force form,the enclosed system is divided into a coherent body type and a superimposed stress type.This paper also studies the structural forms that fully enclosed wheel-spoke tension structures may realize,and preliminarily analyzes mechanical behavior of various structural forms.
