高耸结构满应力截面设计

讨论了高耸结构满应力截面设计问题，首先建立了高耸结构的力学模型，然后通过考虑一个微元体的平衡得到了高耸结构截面应力计算公式，最后得到了高耸结构满应力设计控制方程，由于该方程无法得到解析解，利用ＭＡＰＰＬＦ软件给出了两个算例的数值解。第１个算例是２４ｍ高１００ｍ＾３水塔支筒载面设计，主要考虑了风荷载及自得的影响，最后得到两个算例直径变化曲线，根据满应力设计的结果与工程结果比较，体积得到了大大地优化。

The Full Stress Design of High Structures

The full stress design of high structures is discussed in this paper. First, The mechanics model of a high structure is built. By considering the balance of an element, the stress formula is obtained. Then, the governing equations of the full stress design of high structures in various load conditions are presented. The analytic solution to the problem is so difficult that MAPPLE software is used for two examples. The first example is to design the section of the column of a water tower whose height is 24 m and whose volume is 100 m 3. According to design standards, the seismic load is considered. In the second example, 60 meters high brick chimney is designed, by considering the influence of wind load and the dead weight. We have obtained the curve of diameter of the examples. As compared with engineering design, the volumes are optimized.
