| 概要 |
The parallel-member attachng is a useful measure to renforce steel-tube transmission towers against wind loads. In some cases, however, an original method of fixing the parallel members is not availab...le. So the authors have developed new three devices: a reinforced band, an improved reinforced band and a double reinforced band to fix the parallel members. These devices make use of frictional stress of the band against the main posts of the steel-tube transmission tower. The compression-tensile tests of those reinforced members showed satisfactory validity of the parallel-member attachnent method by the double reinforced band. In addition, a wind tunnel test was conducted to confirm aerodynamic characteristics of the reinforced member by the parallel-member attaciment. The test results indicated that the drag factor of the reinforced member was less than 0.2 and was dependent on the wind direction.続きを見る
