“…The effects of concrete cover, concrete type, load eccentricity on column fire resistance and limited heating on column residual strength were investigated. Test data show that (1) concrete cover significantly improved column fire resistance, and (2) lightweight concrete generally had higher fire resistance compared to normal weight concrete, the latter being more susceptible to spalling. Nevertheless, it is felt that the chosen range of load level 0.27 to 0.36 did not cover the higher end of practical load level (say 0.5, 0.6).…”
