摘　　要：阐述了钢-混凝土混合塔架在预应力设计时需要考虑张拉控制应力的选择、预应力损失的计算和预应力钢绞线应力设计值的计算。在总预应力设计时,需要同时满足正常使用极限状态和承载力极限状态的计算。介绍了目前国内外混塔在正常使用极限状态验算时所采用的不同荷载方法。最后,给出了既满足结构安全性,又兼顾了经济性的设计建议。Several contents are expounded for prestress design of wind turbine hybrid towers,including the control stress for tensioning,the loss of prestress and the total prestress.The structure should meet the calculation for the serviceability limit states and ultimate limit states.The load combinations are discussed for the serviceability design.A suggest is given for the prestress design of wind turbine hybrid concrete towers.The suggest indicates that it account for the safety also economical.
