圆筒形结构由于受力合理,节省材料,在粮仓、水池、水泥库、煤仓等特种结构中得以广泛应用。圆筒形结构内力和位移的常用计算方法没有考虑剪切变形的影响,其适用条件上也往往受到限制。本文在考虑剪切变形影响的圆筒形结构计算模型的基础上,利用初参数法,推导不同荷载作用下所增加的附加项和不同边界约束条件下的初参数的圆筒形结构计算公式。利用上述公式能较准确地计算不同荷载及其组合作用下的内力和位移,得到的数据可供工程设计人员参考。
Cylindrical structure due to force reasonable, save material, widely used in special structures such as granary, pool, cement warehouse, coal bunker. Commonly used methods of calculating the internal forces and displacements of cylindrical structures do not consider the effects of shear deformation, and their applicable conditions are often limited. Based on the calculation model of the cylindrical structure with the influence of shear deformation, this paper deduces the formula of the cylindrical structure with the additional parameters under different loads and the initial parameters under different boundary conditions by using the initial parameter method. Using the above formula, the internal forces and displacements under different loads and their combinations can be more accurately calculated, and the obtained data can be referenced by engineering designers.
