Abstract

Abstract

Due to the fact that because of the maximum design wind speed is low and without considering the height variation factor of wind pressure, the tower in operation is usually damaged and collapsed by the strong wind. It is a serious threat to the safe operation of the transmission tower. It is a pressing question to resist the strong wind by reinforcing and strengthening the tower. According to the engineering experience, the reinforcement and strengthening method is proposed, which can make full use of the bolt holes of leg members. In order to verify the feasibility of reinforcement and strengthening method, five model towers are tested in laboratory. The comparative analysis of bearing capacity of these towers shows that this method has a remarkable improvement of bearing capacity. Through the analysis of the test result, the calculation method of bearing capacity is proposed.
