← Expert Q&A Q6. A simply-supported beam spans 10 m and is made from a 700WB150 steel section. A static vertical concentrated load of 400 KN is applied as shown in Figure. In the event of a fire, the temperature of the steel rises at a constant rate of 15 °C per minute up to a maximum of 750 °C. Assume that, at 20 °C, the steel has a yield stress of 300 MPa and Young's Modulus of 200 GPa. The ambient temperature (before the fire starts) is 20 °C. Determine whether the beam will collapse during the fire, and if so, how long after the start of fire will this occur? 6 m Self weight 400 kN 4 m
