Abstract To improve the behavior of hollow concrete filled steel tube, a novel type reinforced circular tubular member (RHCFST) was put forward and its axial studied. The finite element analysis model 12 RHCFST short columns under compression established by using ABAQUS. influence tube’s strength wall thickness, diameter bar with normal strength, sandwich concrete’s thickness on mechanical prop...

To study the axial compression performance of a steel-reinforced ultra-high-performance concrete-filled square stainless-steel tube (SR-UHPCFSSST), eight specimens were designed with different length-to-diameter ratios and skeleton contents, tests numerical simulations performed. Damage pattern, ultimate load capacity, load–displacement curve data obtained. Finite element analysis was performed...

This paper presents test results obtained from an experimental investigation to check the feasibility of reinforcing laminated bamboo columns by using aramid fiber reinforced polymer (AFRP) composites and examine effect slenderness ratio on AFRP columns. Eighteen full-scale were grouped into 6 categories including 3 specimens without reinforcements. Obtained used study failure modes, ultimate l...
