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 temperature

amplitude

initial displacement and exterior excitation on the nonlinear vibration were discussed. The example indicates that the temperature has great influence on the nonlinear vibration of monolayer cable net and the vibration of monolayer cable net for pointsupported curtain wall shows a hard spring characteristic.
