title = "Fire-resistance evaluation of double CFT columns under central axial load",
abstract = "Studies and tests (D.K. Kim et al. 2005; K.S. Chung et al. 2008; S.H. Park et al. 2008) have proved that unprotected CTF columns can resist a fire for up to two hours under strong axial load and heat. However, the fire-proof construction and management code recently established by the Ministry of Land, Transport and Maritime Affairs prescribes that the columns of high-rise buildings over twelve stories resist fire for three hours at least. Accordingly, double CFT columns using SPSR400 steel with concrete compressive strength of 36.1MPa are suggested in this study as a way to meet the fire-resistance requirement. In order to compare their fire-resistance with that of unprotected CFT columns, full-scale structural test and numerical analysis were conducted with the variables of central hollow ratio, concrete strength and steel tube strength. It is evaluated whether double CFT columns can resist fire for more than three hours and thus be appropriate to over 12 story high-rise buildings.",
