摘要: High-strength concrete (HSC) columns are usually provided with heavy confining steel within the potential plastic hinge region to restore flexural ductility. However, as effectiveness of decreases strength, required content for high-strength becomes very large, which causes congestion in proximity beam–column joints. A better method is adopt a concrete-filled-steel-tube (CFST) column, uses hollow tube confine concrete. Compared ordinary reinforcement, provide more uniform pressure core and reduce congestion. Nonetheless, major shortcoming that imperfect interface bonding occurs at elastic stage dilates than compression. This adversely affects confinement strength modulus. To resolve the...
