Retrofitting of Angle Legs of Transmission Towers to Increase Load Capacity

As a result of changes in design code requirement for wind loads, the increase in power demand, and the growing communication industry, many existing steel lattice transmission and communiction towers now require strengthening to meet increased load requirements. Various strengthening methods are being utilised by engineers in this area, with leg reinforcement being one of the most common methods. However, even though it has been used in practice for some time, there has been little reasearch done into its effectiveness, until this study.
