Abstract

Conventional reinforced concrete (RC) structures generally require long construction periods and high costs due to many on-site temporary form works. In this study, the prefabricated columns with permanent thin-walled steel form integrated with reinforcement cage (PCSFRC) system have been developed to reduce labor costs and construction time by minimizing the temporary works. The structural performances of the PCSFRC have been conducted under eccentric compressive loads, introducing axial forces and moments to the specimens at the same time. Experimental results of the PCSFRC specimens showed more ductile behaviors than those of RC and concrete filled Tube (CFT) column specimens. Their member strengths were also compared to those specified in current design codes.
