A Computer Study of Reinforced Concrete Columns in a Fire

The paper sets out by examining methods that have been suggested for designing reinforced concrete columns in a fire, together with their drawbacks. The main part of the paper dicusses the theoretical background of a recently developed computer program SAFE-RCC (Structural Analysis of Fire Exposed Reinforced Concrete Columns) which takes account of the change in loadcarrying capacity and stiffness of a column during a fire, together with the change in stiffness of the framingsystem at each end of the column. Following the presentation of results from some proving tests, the results from an exploratory series of runs are presented in which it becomes very clear that the flexural stiffness of the restraint system plays a large part in determining the fire response.
