Fire resistance of ultra-high performance concrete columns subjected to axial and eccentric loading

This paper experimentally investigated fire resistance of UHPC and HPC columns under the ISO 834 fire curve. Effects of concrete strength, inclusion of fibers, and load eccentricity were investigated. Spalling behavior, failure mode, temperature distribution, axial deformation, mid-height column deflection, and fire resistance were measured and analyzed. From the results, columns with plain UHPC matrix were highly susceptible to explosive...
