概要 |
The authors have devised two methods, the parallel member attachment method and the redundant member attachment method, aimed at reinforcing steel-tube transmission towers for wind loads. The methods ...were able to achieve enhanced strength using simple, inexpensive construction techniques. To evaluate their effects, a compression strength test was conducted using test models in cases where the proposed methods were applied or omitted. The strength values obtained in the test were compared with a FEM calculated value. A man-powered vibration test was implemented in both cases, to examine the effects of reinforcements on the dynamic characteristics. The tests showed the satisfactory validity of the proposed reinforcement methods.続きを見る
