- Abstract
Two full-scale beam-column specimens made of ordinary concrete and self-consolidating concrete (SCC), respectively, were tested under ISO 834 standard fire exposure for 3 hours. The testing was intended to assess the fire resistance of part of a seven-story residential building designed for seismic conditions according to ACI 318-08. This paper is focused on the discussion of the beam results. The vertical deflections at load points, horizontal displacement, and rotation at the freely supported beam-end of each beam of the two assemblies were very close during the heating phase and residual strength tests. The SCC specimen exhibited more severe explosive spalling. Both specimens failed in ductile flexural mode with the residual flexural strength of approximately 80% times that calculated at ambient condition. The measured temperatures of concrete and steel are predicted reasonably well by a commerical finite element program using the thermal properties suggested in Eurocode 2.
