ULTIMATE STRENGTH AND DUCTILITY OF LOW-YIELD-RATIO NIGH-STRENGTH STEEL BEAM-COLUMNS
|
抄録（英）：
It is very important for structural steel to possess an adequately low yield ratio in order to provide steel members with ductility. For this reason high-strength steel with tensile strength greater than 60 kgf/■ has been considered unsuitable for seismic design because of its high yield ratio. However, recent developments in steel production practice in rolling mills have realized 60 kgf/■-tensile-strength steel with yield ratio less than 80 %. The ultimate behavior of beams and beam-columns with H-shaped sections built from this new steel was experimentally investigated, from which empirical formula for ultimate strength and ductility were proposed in this paper.
