| 摘 要： | 造粒塔为中空圆柱筒体结构,采用新型纯钢结构体系避免了传统混凝土结构塔体对工艺流程的制约,成为新的发展方向.但由于其底部70多m的净空要求,使得钢柱的稳定设计成为结构设计的关键.本文以某钢结构造粒塔为工程实例,介绍了钢塔整体稳定的设计方法,即考虑塔顶假想水平力,采用二阶分析方法进行内力计算.这样,有效地解决了塔柱计算长度...

| Abstract: | Prilling tower is a hollow cylindrical shell structure.Because of avoiding the restriction of traditional concrete tower to the process flow,the steel structure tower became the development trends.For the tower has more than 70 meters clearance requirement,stability design of the steel columns is the key point of strucutre design.Taking one actural steel structure prilling tower as an example,the steel tower sturcture stability design process is introuduced in this paper.With imaginary horizontal force appl... |
