| 摘 要： | 塔式起重机塔身的抗扭刚度与塔身腹杆布置密切相关。文章对常用的几种塔身腹杆体系在受扭矩作用时，在弹性范围内的内力分布、位移及抗扭刚度进行分析。从而探讨在塔身截面和腹杆尺寸相同的情况下，采用适当的腹杆体系．可获得较理想的抗扭刚度。

| Abstract: | Torsional stiffness of tower crane mast is closely related with the arrangement of Web members of the mast. This paper analyses the distribution of intemal forces, the displacement and the torsional stiffness of web member system of common tower carane masts under the load of torsional within the elastic limits.Excellent torsional stiffness can be obtained when suitable web member system is utilized under the conditions of same cross section of mast and same dimensions of web members. |
