Abstract
The reinforced structure was designed for local cylinder's replacement of the tower. Intensity performance study for reinforced structure was carried out through finite element method and influences on stress distribution of the tower structure were analyzed by comparing with five design conditions and different number of strengthen components. The results showed that most dangerous working condition of the tower was happened when wind loads and earthquake loads were applied from 180° direction. Moreover, structure strength of tower increases with the decrease of reinforced components and the stress significantly increases while the number of strengthen components reduced to 4. Therefore, the reinforced structure improved with 4 strengthen components was put forward, which satisfied the requirement of strength. And the buckling resistance was 1. 56 times of standard rules, which meet construction requirements. So construction cost was reduced and it was meaningful for actual engineering.
