Fire can be considered as a destructive hazard that attacks concrete structures. Exposing to high temperature causes deterioration in strength and spalling for high strength concrete members. In this research the effect of high temperature on the different high strength concrete specimen shapes is studied as a represent of circular and rectangular column sections. For this purpose, cube and cylindrical shaped specimens were made from polypropylene fiber contained high strength concrete, as well as the plain high strength concrete. After moist curing periods for 7, 28 and 90 days, the specimens were subjected to high temperatures of 450 and 6500C, and their residual compressive strength were evaluated. Cube specimens exhibited higher residual strength than cylindrical specimens and the superior stability of rectangular section columns compared to circular ones at high temperatures is concluded.
