Study on the Equivalent Fire Load of Axially Loaded Concrete Columns

摘要

Building fire is dangerous to structures. It is important to accurately compute the equivalent fire load. First, temperature fields of a reinforced concrete column with four face exposed to fire were simulated using finite element method. Then, two step simplified model was applied to compute the transformed area of the column. Finally, the equivalent fire load was obtained based on the transformed area. Result shows that the method is applicable to compute the equivalent fire load.
