摘　　要：介绍了钢塔架的静力计算方法,指出空间桁架法适用于任何类型的塔架,计算精确度较高,通过对比分层空间桁架法和midas有限元程序计算结果,了解两种计算方法的误差,为以后的设计提供很好的指导经验。The thesis introduces static iron tower calculation methods, and points out that spatial truss method is suitable for any type of tower with high calculation accuracy. Through comparing calculation results of hierarchical-spatial truss method and midas finite element program, it finds out their calculation errors, which has provided good guiding experience for future design.
