Comparative Analysis of Wind Load for Transmission Tower between Chinese and American Codes

Abstract:

Wind load computation formula for transmission tower of 《Technical code for the design of tower and pole structures of overhead transmission line》 and 《Design of latticed steel transmission structures》 are studied in this paper. The differences of basic wind speed, height variation factor of wind pressure, shape factor and wind load factor are compared in detail, respectively. The results show that the wind load defined in the Chinese code is little different from the American code. However, some parameters are still worthy of further discussion. The analysis results can be a reference for the design of transmission tower.
