Abstract
This paper presents a series of eight fire tests conducted on circular tubed steel-reinforced concrete columns subjected to eccentric loads. The cross-sectional temperature, axial displacements, fire resistance, and failure modes were recorded and discussed. The influence of key parameters-load ratio, load eccentricity, and wall thickness of the steel tube-on the deformation and fire resistance of the circular tubed steel-reinforced concrete columns were also investigated. Subsequently, the coupled thermal-stress model was developed using the ABAQUS program to investigate the effects of key parameters on both thermal distribution and fire resistance. For the thermal analysis, the considered parameters comprised the cross-section dimensions, the thickness of the steel tube, and types of concrete, and for the fire resistance analysis, they were the load ratio, load eccentricity, thickness of the steel tube, and concrete and H steel strengths. The results showed that the cross-section dimensions have a relatively larger influence than the thickness of the steel tube and the types of concrete on the temperature distribution of the columns. Regarding the fire resistance of the columns, the effects of the load ratio and thickness of the steel tube are remarkable, whereas the concrete and H steel strengths and the load eccentricity have a minor influence. The calculation methods were simplified to determine the steel temperature of a column in a fire, and the N-M curves of the eccentric members subjected to ISO 834 standard temperature are presented. Using the simplified methods, the steel temperature, and the N-M curves of the eccentric circular tubed steel-reinforced concrete columns can be evaluated for any value of the significant parameters, such as the thickness of the steel tube, load ratio, and concrete strength.
