Abstract
In Japan, mid-sized electric transmission towers are made of steel angle members connected by high-strength bolts and are mainly designed to withstand wind loads. However, recent collapses due to the increasing wind intensity caused by climate change have led to a high demand for the reinforcement of conventional towers currently in operation. This paper reports the flexural buckling strength evaluation method for reinforced steel angle members under eccentric load. The study utilizes a theoretical approach to derive the evaluation formula, considering the effect of the eccentric load and the amount of reinforcement. Finally, small-scale experiments validate the proposed design formula, which can reasonably evaluate the strength of reinforced steel angle members.
