AbstractThis presentation provides information on the ongoing studies on performance evaluation of reinforced concrete columns in fire and extreme forces. NRC-IRC has been investigating a new fire resistance testing approach that will consider the effects on a whole building, rather than just individual elements, by using analytical and computer simulations. This new approach is being developed for use in estimating the fire-resistance of reinforced concrete columns, within a building frame, taking into consideration the effect of the structural system, thermal expansion and lateral loads. A brief introduction of this new testing method will be provided. Furthermore, studies have been explored on performance assessment of columns in fire and under extreme forces such as an earthquake. This includes post-earthquake fire performance evaluation of reinforced concrete columns and post-fire seismic resistance of reinforced concrete columns. Investigation on the first subject is being carried out. A study on the second subject has been completed on assessment of the residual strength and lateral/seismic load capacity of reinforced concrete columns after fire exposure. The results will be presented in brief along with a future research on blast and fire.
