摘要
框架和塔连接后可简化为一个弹性支承的系统,利用弹性连续体分析法求解振动方程,推导出了计算框架塔自振频率的理论公式。试验结果表明:本模型的计算值与试验值吻合良好,可以为工程实践中的应用提供理论依据。
On the assumption that the framed tower can be represented by multi-segment cantilever carrying a spring support, a mathematical expression to determine the natural frequencies of a framed tower is obtained by using the equation of the transverse vibration for the analytical model of elastic continuous body and the method of numerical solution. By comparison, calculated values are in good agreement with experimental values.
