Steel Buildings in Europe

Part 7: Fire Engineering 7 - 32 The following buildings can de designed by these methods:  Storage and industrial buildings with steel structure. Either steel portal frames with standard H or I hot rolled profiles or equivalent welded plate girders, or steel frames based on lattice beams with columns in standard H or I hot rolled profiles or equivalent welded plate girders  Storage and industrial buildings of portal frame construction divided in several cells, separated one from each other by fire walls. These walls can be either perpendicular to the steel portal frames or parallel to the steel portal frames (see Figure 5.8). These methods were specifically developed for storage and industrial buildings but they can also be applied to other type of single-storey buildings. fire wall perpendicular to the steel frame fire wall parallel to the steel frame Figure 5.8 Location of fire wall compared to steel frames Calculation methods (see Section 5.5) are only required when fire walls are perpendicular to steel frames of the building and the building height exceeds 20 m 5 . When fire walls are parallel to steel frames, the risks of collapse towards the outside and progressive collapse (between different fire compartments) can be simply avoided by following the recommendations in Section 5.5.3.
