| 摘 要： | 考虑温度变化及几何非线性影响，采用连续化理论导出了单层索网幕墙结构非线性振动方程。通过Galerkin方法，将偏微分程转化为常微分方程，并采用L—P法及KBM法对常微分方程进行了求解。以中关村文化商厦平面索网幕墙结构为实例，讨论分析了温度变化、振幅、初始位移、外激励等因素对单层索网幕墙结构非线性振动的影响。算例表明，温度变化对单层索网幕墙结构非线性振动影响较大；单层索网幕墙结构非线性振动呈现“硬弹簧”特性。

| Abstract: | Taking the temperature effect and geometric nonlinearity into consideration,the nonlinear vibration equation of monolayer cable net for point-supported curtain wall was derived by assuming the net as a continuum membra.By the Galerkin method,the partial differential equation was transformed into ordinary differential equation which was solved with L-P method and KBM method.Taking the monolayer cable net for point-supported curtain wall of Zhongguancun Culture Building as an example,the effects of temperatur... |
