水平リブの有無と長さを変化させた高力ボルト非突出型エンドプレート接合の載荷実験

抄録

In order to clarify the effect of horizontal stiffeners and to confirm the validity of the bolt force estimation formula proposed by the authors, an experiment was conducted on bolted flush end plate connections with and without horizontal stiffeners, and with varying lengths of the stiffeners. The experimental results showed that the stiffness and yield strength of the connections were greatly improved by the installation of horizontal stiffeners. It was also found that lengthening the horizontal ribs had little effect on the stiffness and yield strength improvement, but it did reduce the strain on the web plates. Finally, it was confirmed that proposed bolt force estimation equation gives a safe evaluation in comparison with the experimental results.
