Considerations on the performance of precast concrete structures in fire situation

The increasing use of precast concrete as a structural solution for different types of buildings, such as industrial and commercial buildings, has become a good, accessible choice, especially regarding construction time. However, in a fire situation, certain characteristics of this construction system that are normally considered as advantages could become disadvantages. With large spaces, large open spans, good ventilation and the storage of flammable materials, these buildings provide the ideal setting for fire spreading and the consequent loss of structure carrying capacity. In this study, we present the implications of a project that uses precast concrete in a fire situation, and we raise points for discussion on alternatives to mitigate risks, based on national and international bibliographic references currently used by the technical and academic community.
