摘要
将酒杯型铁塔塔头简化为平面刚架进行受力分析,具体包括上曲臂受力分析(细分为上曲臂与横梁成直角和不成直角2种情况),下曲臂受力分析,上、下曲臂在2种极端情况下的受力分析(交点上移至梁处和交点下移至塔身顶点高度处),得出结论:比较合理的酒杯型铁塔塔头型式是在保持电气间隙要求的前提下,上曲臂和下曲臂交点靠上,上曲臂向内弯。
The stress analysis is achieved by simplifying tower head of cup type tower as flat steel frame.The stress analysis includes stress analysis of upper crank（subdivided as the upper crank and the beam are on the square and the opposite）,lower crank as well as upper crank and lower crank in two extreme cases（intersection point shifts up to the beam and down to tower top）.It is concluded that the intersection point of upper crank and lower crank must be on the top and the upper crank must be incurved,which accords with reasonable tower head type of cup tower on the premise of ensuring electric clearance.
