Abstract(s)
Partially encased columns (PEC) have better fire resistance when
compared to bare steel columns, due to the existence of concrete between the
flanges. The aim of this study is to develop a new proposal for the calculation of
the buckling strength of partially encased columns, embedded on walls, under
fire conditions. This proposal is based on the current calculation method proposed
in Annex G of EN 1994-1-2. This study uses the finite element method to
calculate the average temperature of seven components. The average temperature
is then used to find the buckling resistance of composite columns when submitted
to fire from one side. This solution method is carried out using 30 different cross
sections. All cross sections are exposed to the standard fire curve ISO834 from
one side, assuming the specific fire rating of 30, 60, 90 and 120 min.
