Abstract

Ten slender high strength concrete(HSC) filled rectangular hollow section(RHS) steel tubular columns were tested.The primary test parameters were slenderness ratios varying from 25^4 to 71^6,steel ratios of 8.2% and 14.6%,height-to-breadth ratios varying between 1.0 and 1.6.Meanwhile,a nonlinear analysis program was produced to calculate the bearing capacity of the high strength concrete-filled RHS tubes.The experimental results agreed well with those of the numerical analysis.Furthermore,the influences of the factors,such as steel ratio,concrete strength,steel yield strength and height-to-breadth ratio,on the stability factor-slenderness ratio curves were investigated.The results showed that the bearing capacity decreased rapidly with the increasing of the slenderness ratio,and the height-to-breadth ratio(varying from 1.0 to 1.6) had no evident influence on the stability factor and relative deflection at the mid-height.
- high strength concrete( HSC ),
- rectangular hollow section( RHS),
