摘要
本文对具有离散支撑的双曲冷却塔在自重及集中荷载作用下的内力、位移作了分析计算，采用半解析有限元法，子午向用Hermite插值，环向用三角级数展开。集中力用δ函数表示。对于冷却塔边界离散支承，利用等效作用的原则，用方波函数进行二次计算。本文的计算结果对施工中出现的集中力问题，有一定的指导意义。
Ih the paper, it presents a internal force and displacement analysis method forhyperboloidal cooling towers on discrete supports which subjected to deadweight and con-centrated force It applies semi-analytic finite elements method, that is, Hermite insert inmeridian and trigonometric series in circle The concentrated force is expressed by func-tion. The discrete supports using principle of equal effects, the boundary of cooling towerare calculated with square-wave function in the second time. The result of the paper pres-ents certain guide for concentrated force in practice working.
