Influence of assembly stress on ultimate load carrying capacity of transmission towers

In recent years, for the influence of all kinds natural disasters, transmission tower’s collapsing or line’s damage presents a growing trend. The assembly stress in towers is often ignored when people analyze accidents. To study actual stress, production process should be summarized and simulated. Find out method to calculate simulate by using finite element analysis software. Trussed beam hybrid model built. ultimate load carrying capacity with studied. position which unfavorable dimension error determined through variation bar quantity error. It founds that small there only one pole existing size than 1% pole’s length; When are number poles located at tower leg will produce great on Ultimate towers.
