For investigating effect of heating and cooling process simulating fire on mechanical properties of Steels for Bridge High Performance Structure (SBHS), a series of experiment was carried out. The heating of 600℃ did not change the mechanical properties of SBHS from those without heating and cooling. The heating of 900℃ and air cooling decreased the mechanical properties of SBHS due to softening. The heating of 900℃ and water cooling increased the ultimate strength due to hardening; however, it decreased the yield stress and elongation of SBHS to the level below that required by JIS.
