通常水塔、球罐等建筑结构的基础刚度一般都很大,基础底部各处地基变形差别很小,因此本文假定环形基础以及地基模型均为弹性体,且认为地基反力沿基础梁环向均匀分布。继而简化并建立了力学模型,并根据虚功原理对环形基础进行内力分析,给出了环形基础弯矩、扭矩以及剪力的一般表达式,作为一般工程的环形基础梁的初步设计及校核使用,具有足够的精度。 Generally, the foundation stiffness of water tower, sphere tank and other building structures are generally very large, and there is little difference in foundation deformation at the bottom of the foundation. Therefore, this paper assumes that the annular foundation and the foundation model are both elastomers, distributed. Then, the mechanical model is simplified and established. According to the internal force analysis of the ring foundation based on the principle of virtual work, the general expressions of the moment, torque and shear of the ring foundation are given. The preliminary design and check of the ring foundation beam Use, with sufficient accuracy.
