| Abstract |
The concrete filled tubular column (CFT) is a composite member with high strength and ductility due to the interaction between steel tubular
and concrete. However, the square steel tubular of a CFT column that is welded has the characteristic of the quality being determined by the
influence of the environment and technology. Therefore, it was planned not to use welding on CFT columns. Alternatively, increased strength
and ductility occurred when the cross section of the steel tubular was improved by using stiffeners. The four steel plates were prefabricated
and manufactured in an interlocking form by applying sawtooth rib detail, and the flexural performance was evaluated through cyclic loading.
As a result, the flexural performance of the prefabricated CFT column with ribs were similar to the square steel tubular. The prefabricated
CFT column with ribs was intended to be presented as a solution to the problem of welding the square steel CFT column. |
