EXPERIMENTAL STUDY ON OVERALL BUCKLING OF STEEL H-SECTION MEMBERS REINFORCED WITH CARBON FIBER REINFORCED PLASTICS

Abstract

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.
