超鉄鋼高力ボルトを用いた摩擦接合パイロット試験 [in Japanese] Pilot Experiments of High Strength Bolted Friction Joints using Ultra High Strength Bolt [in Japanese]
Access this Article
Ultra high strength bolt, which strength is more than about 1000MFa has been developed by NIMS. For steel connections of civil/building structures, such bolts will make it possible to reduce the fabrication/construction cost and to change such joints simple and rational. In this study, pilot experiments using Ultra high strength bolts has been carried out to discuss feasibility of application of such bolts and to find further research problems for general use. 3 experiments have been executed; tensile tests for bolts considering actual situation of use, nut rotation angle tests and friction tensile tests for joints.
