一绪言在单层工业房屋钢骨架的结构设计中,静力计算部分常常占有相当大的比重,需要耗费较多的计算时间,因此,国内外有很多学者在结构的静力计算方面进行了许多研究工作,以求找到此较准确的近似计算方法,以使在不影响结构计算所要求精确度的条件下,达到减轻静力计算工作,节省计算时间.在厂房钢骨架的近似计算方法中,一种方法是假定横梁的刚度为无限大(屋盖竖直荷重作用下不能如此假定)在一定的条件下,这样应用差误是不大的,实际设计中也常常采用此种计算方法.此外,目前在厂房骨架的静力计算中也提出了一个新的问题——厂房骨架的空间工作问题.在静力计算中考虑骨架的空间工作可以使计算更加接近于实际工作情况,同时可以得到进一步节省钢材,特别是在目前情况下,大型屋面板得到了广泛的应用,屋面刚度对骨架空间工作的影响就更为显著, An introduction In the structural design of a single-story industrial building steel skeleton, the static calculation part often occupies a considerable proportion, and it takes a lot of calculation time. Therefore, many scholars at home and abroad have carried out many aspects in the static calculation of the structure. Research work in order to find this more accurate approximate calculation method, so that under the condition of not affecting the accuracy required by the structural calculation, the static calculation can be reduced and the calculation time can be saved. In the approximate calculation method of the steel skeleton of the factory building, One method is to assume that the stiffness of the beam is infinite (it cannot be assumed under the vertical load of the roof). Under certain conditions, the application of the error is not significant, and this calculation method is often used in the actual design. At present, a new problem has also been raised in the static calculation of the plant skeleton - the spatial work of the plant skeleton. Taking into account the space work of the skeleton in the static calculation can make the calculation closer to the actual work situation, and at the same time can obtain further savings. Steel, especially in the current situation, large-scale roof panels have been widely used, and the effect of roof stiffness on the work of skeleton space is even more pronounced. ,
