摘要
介绍一种单管塔计算的半解析方法。基于结构力学力法原理并考虑P-Δ效应对单管塔顶位移进行了理论推导并给出了相关等式;利用MATLAB7.0数学计算软件进行积分求解,其结果与其它有限元软件的计算结果吻合较好。该方法可用于单管塔的工程设计计算。
Introduced a steel pole of a semi-analytic method. Based on principle of the force method of the structural mechanics,a top displacement which is taken into account P-△ effect was theoretically driven and the relevant equation was got. Using MATLAB7.0 mathematical integral solution,the results are in good agreement with the calculated results of other finite element software. The formula and method presented in this paper can be used in the tube tower practical design.
