摘　　要：采用材料力学的叠加法和自编的MATLAB程序,计算了高塔设备在风载荷和自重联合作用下的塔顶静挠度,并推出了考虑自重影响时塔顶静挠度的计算公式。分析和计算的结果表明,对于自重和长径比均较大的高塔,必须考虑塔体自重对塔顶挠度的影响,且只要将高塔分三段以上进行类似的分析,就足以满足工程计算的精度要求。The superposition method in mechanics of material and a MATLAB Procedure was used to calculate the top deflection of tall tower under both of weight and wind pressure. The corresponding formulation was deduced. The results showed that the effect of weight to top deflection of the heavy and tall tower column can not be ignored. When using this method to analyze tall towers, it will be accurate enough to divide the column into three parts.
