鋼板を接着補強した送電用山形鋼鉄塔腹材の接合部載荷実験と有限要素法解析 FUNDAMENTAL STUDY ON SEISMIC RETROFIT FOR ANGLE BRACE CONNECTIONS OF TRANSMISSION TOWER USING STEEL PLATE ADHESIVE BONDING

 本研究は,送電用鉄塔等の接合仕様に対 しても適用可能な山形鋼腹材接合部補強の一工法として,鋼構造用接着剤を用いた山形鋼接合部補強の可能性に着眼し,山形鋼接合部の平板部に鋼板を接着する補強工法に関して,限られた山形鋼断面・材料特性においての一検討ではあるものの,同工法の基礎的な知見収集を試みました。社会人ドクターの検討です。論文はこちら

To reinforce the connections of angle diagonal braces of power transmission towers, retrofit methods attaching the additional steel plates including adhesive bonding are proposed. Comparing to the bolt attachment, adhesive bonding attachment can add the additional plates without the loss of sectional area. In this paper, real-size mock-up tests and finite element analysis for the reinforced connections are carried out and it is confirmed that adhesive reinforcement reduces the damage concentration around the existing bolt holes of angle member and improves deformation performance of brace and ultimate strength of connections.
