炭素繊維強化樹脂により補強した鋼製H形部材の全体座屈に関する実験的研究

抄録

This study investigated a seismic retrofitting design method using carbon fiber reinforced plastics for steel truss bridge members. A series of compression loading tests were conducted on H-section steel members reinforced with carbon fiber reinforced plastic in order to clarify buckling behavior and reinforcing effects on the load carrying capacity after buckling. Test results showed increase in the buckling strength and effects on the post buckling behavior. Lastly, evaluation methods for the buckling strength for CFRP reinforced steel members were proposed.
