To develop fire-resistant design for 60-minute semi-fireproofing of steel bar-timber composite beam, burning tests were conducted and the followings were identified.
1. By gluing lamina of 90 mm in thickness at the lower surface of beam, the beam maintained bending and shear capacities calculated using the proposed resisting portion model.
2. When the area was divided into three equal portions in the beam width direction, the central portion was still below 70℃ even after 60 minutes of burning, and the rebar within that area was also below 30℃, a temperature situation that would provide resistance as the composite beam.
