一、引言环形预应力混凝土电杆结构的传统设计方法是根据电杆的外形尺寸及标准荷载等级,先凭经验假定电杆的配筋量,然后按规范要求进行强度、抗裂度的复算及其它各项验算~(1·2),这种方法计算工作量大,常常要经过数次反复计算才能满足各种设计条件。对于部分预应力混凝土电杆的结构设计,具有预应力钢筋和非预应力钢筋两个变量,计算工作量更大。此外,按传统设计方法确定
I. INTRODUCTION The traditional design method of the annular prestressed concrete pole structure is based on the external dimensions of the pole and the standard load level. It first assumes the reinforcement amount of the pole by experience, and then carries out the calculation of strength and crack resistance according to the specification. And all other calculations ~ (1 · 2), this method is computationally intensive and often requires repeated calculations to satisfy various design conditions. For the structural design of partially prestressed concrete poles, there are two variables: prestressed steel bars and non-prestressed steel bars, and the calculation workload is greater. In addition, according to the traditional design method
