A fire-resistance rating typically means the duration for which an architectural structure (beams, pillars, flor slabs, walls, and the combination of all the mentioned elements) can maintain their features and withstand the heat of a potential fire during a given time.
Technical norms divide in levels (which are properly referred to as “classes”) the performances required for the building structures. In other words, those are prescribed by the activity-specific vertical rules, such as for parking areas, schools, hospitals, business activities. If no specific firefighting regulation for a given activity exists, the required performance is inferred from the fire prevention procedure which has previously been submitted to the competent Fire Brigade Department.
A special structural engineering unit has been set up by Guidi & Partners; it is concerned with the needed assessment and interventions targeted at proving the prescribed fire resistance class for the analyzed structure; when needed, a Fire Resistance design project and model is submitted (Fire Resistance Certification). Our firefighting professionals’ knowhow has grown up during the multiyear experience Guidi & Partners has been gaining with the Performance Based Design approach.
The advanced analytic procedure we perform allows the simulation of the structure and fire reaction regardless of its complexity, thus determining the real fire resistance class of the structure itself.
This kind of analyses results mostly in higher performances than those certifiable through the traditional approach; it may prevent requalification and consequently reduce both building adjustments and building works inconvenience.
Any activity can be subjected to analytic fire resistance assessment- parking areas, hospitals, business activities, factory warehouse and production sites, apartment blocks.
