Steel Buildings in Europe

Part 7: Fire Engineering 7 - 37 K 1 1  2  n = 1 m 2 = 3 K 2 Figure 5.13 Fire in a compartment at the end of the building 5.5.3 Example of fire scenarios The above calculations must be performed for all possible fire scenarios . These scenarios are defined in accordance with the arrangement of the storage building (structure and partitioning) as illustrated in the example in Figure 5.14. Configuration of storage building: 5 spans and 3 cells Cell 1 Cell 2 Cell 3 Fire wall Fire wall Scenario 1: fire in cell 1 Scenario 2: fire in cell 2 Scenario 3: fire in cell 3 3 fire scenarios need to be considered Figure 5.14 Fire scenarios according to the arrangement of the building 5.6 Design recommendations Additional design recommendations for fire walls, façade elements and bracing systems must be put into practice to avoid the collapse toward the outside of the building and the progressive collapse of the steel structure. Obviously, recommendations allow also the collapse of the steel structure under fire condition on either side of fire wall without causing any damage to this wall.
