【摘要】 网架结构的设计分析计算通常将上部网架与下部支承分为两个独立部分进行,其结果与结构的实际受力差别较大,致使结构构件在设计中偏于保守或不安全。结合某体育馆平板网架结构,采用有限元分析软件从整体稳定性、温差作用两个方面对整体建模与上部结构单独建模的整体工作性能进行了对比分析,从而得出一些设计建议,为同类工程提供借鉴。更多还原

【Abstract】 The upper flat grid and supporting structure are separated for structural design,which has a great difference with the performance of actual structure,resulting in some conservatism and insecurity.Taken the specific project of flat grid stadium in a university,the performances of the whole model and the upper flat grid model alone are compared adequately from two aspects including the overall stability,temperature effect,which is made using the finite element analysis software in this paper.The results show that some rational design suggestions are obtained,and those suggestions can provide some reference for similar projects.更多还原
