【摘要】 文章研究了椭圆平面双曲抛物面碳纤维索网在均布荷载作用下的静力特性,建立了其在均布荷载作用下的非线性控制方程,求得了椭圆平面双曲抛物面碳纤维索网静变形时的近似解;在把碳纤维索网与钢丝索网比较的基础上,讨论分析了温度、索网垂度等因素对椭圆平面双曲抛物面碳纤维索网的影响,得出钢丝索网受温度影响较大、碳纤维索网对温度变化不敏感,这对索网的设计具有理论指导意义。更多还原

【Abstract】 By establishing the nonlinear control vibration equation,the static force feature of ellipse double arch paraboloid cable net using carbon fiber cables under uniform load is studied,and the approximate results of static distortion are given.By comparing the ellipse double arch paraboloid cable net using carbon fiber cables with the one using steel cables,the impact of temperature,sag of cable net and other factors on the static force feature of ellipse double arch paraboloid cable net using carbon fiber cables is analyzed.The conclusion is made that the cable net using steel cables is influenced more by the temperature and the one using carbon fiber cables is not sensitive to the temperature change.The result has theoretic significance for the design of cable net.更多还原
