RESEARCH ON WIND RESISTANCE AND BEARING CAPACITY OF TYPICAL METAL ROOF PANELS

依托乌鲁木齐机场改扩建工程机场工程交通中心项目,运用数值模拟的方法建立三维模型,研究金属屋面板厚度、宽度和肋高对其抗风承载力的影响,各个影响因数的对比工况均为5种。结果表明,随着金属屋面板厚度的增加,其抗风能力不断增加,拟合两者之间的关系为线性关系,其拟合决定系数R^(2)为0.9879;随着金属屋面板宽度的增加,其抗风能力呈非线性降低趋势,拟合两者之间的关系为指数关系,其拟合决定系数R^(2)为0.9633;随着金属屋面板肋高的增加,其抗风能力呈现非线性增加趋势,拟合两者之间的关系为幂指数增加关系,其拟合决定系数R^(2)为0.9536。

Based on the Urumqi Airport Reconstruction and Expansion Project Airport Traffic Center Project,a three-dimensional model was established using numerical simulation methods to study the effects of metal roof panel thickness,width,and rib height on its wind resistance bearing capacity.The comparative working conditions for each influencing factor were 5.The research results indicate that as the thickness of the metal roof panel increases,its wind resistance continues to increase.The relationship between the two is linear,and the fitting determination coefficient R^(2) is 0.9879;As the width of the metal roof panel increases,its wind resistance shows a non-linear decreasing trend.The relationship between the two is fitted as an exponential relationship,with a fitting determination coefficient R^(2) of 0.9633;As the rib height of the metal roof panel increases,its wind resistance shows a non-linear increasing trend.The relationship between the two is fitted as a power exponential increasing relationship,with a fitting determination coefficient R^(2) of 0.9536.
