Structural fire design

IDF operates with a group of engineers highly skilled in verification of structures subjected to fire. From the early stages of the design, and through the adoption of the most appropriate measures of passive fire protection, IDF technicians are able to achieve significant cost savings for the fire protection adjustment of buildings by providing, in a short time, cutting-edge, flexible and cost-effective design solutions while guaranteeing that essential fire safety requirements are always met.


A better knowledge of the structural behaviour in case of fire associated with a specialized design allows:


  • greater flexibility in the development of alternative technical solutions for fire protection;
  • significant savings on construction costs of buildings;
  • reduced property management costs choosing protective systems of great durability;
  • resolution of the most complex problems with the adoption of cutting-edge technological solutions.


With constant updates on news offered by the market, IDF is able to answer all the analysis required in a timely and comprehensive manner, dealing with all aspects of structural fire design.
IDF with its staff of highly qualified engineers know not only the requirements of law but also the objectives and means to implement them.

Fire design of new buildings

Aiming at limiting the costs of implementation, engineers of the IDF team deal with the fire design of buildings constructed with any type of material possibly defining the most suitable protective system and providing a specialized technical support during the whole building phase until the release of the final certification.
The collaboration with structural engineers since the first phase of the design is the key to success for a good fire design.

Analysis of resistance of existing structures

Considering that Italy is a country with a large building environment, the IDF technicians are able to perform the most sophisticated analysis on existing structures as regards fire conditions, to minimize the passive protection measures needed to upgrading them.
Also identifying the possible mechanisms of collapse.

Instrumental surveys

The IDF technical experts perform measurements in situ (both in Italy and abroad) and samplings on buildings to determine structural fire resistance with the aid of the most modern technical equipment as required by the nationally and internationally recognized regulations.

Thermal analyses

Through the use of the most sophisticated computational software, the IDF technicians carry out thermal analyses of individual elements, structural parts or entire structures. The thermal behaviour and deformation of the elements subjected to study is defined by performing the analyses in the thermal transient of structures exposed to fire.

Fire resistance certifications

The IDF technicians prepare legal documentation for the fire resistance certification of load-bearing and separating structures built with any type of material, possibly coated with a protective system necessary for their requalification.

Passive protection specialized advice

The IDF study provides the expertise of its engineers to provide specialized advice on the choice of the best passive protection systems for interventions on structures subjected to the thermal action induced by fire curves:


  • ISO 834;
  • hydrocarbons (HCF), modified hydrocarbons (HCFM), RABT, RWS;
  • curve from outside and natural fire curves.

Special Applications in the Oil & Gas sector

The IDF technical staff has extensive experience in the fire protection of onshore and offshore industrial activities with a high risk of fire, especially in the oil and gas sector.
The fire protection of these types of structures is evaluated through the use of a fire curve for hydrocarbons according to the following fire scenarios:


  • Hydrocarbon pool fire: fire generated by a fluid fuel puddle open at the top, according to the standard fire curve of hydrocarbons;
  • Jet fire: turbulent jet flame from liquid or gaseous fuel that generates very high heat fluxes potentially corrosive for the protection system; It constitutes a more severe scenario as compared to the pool fire.


The passive protection systems to be applied to the structures are verified in terms of their behaviour in the presence of the aforesaid fire scenarios by means of specific experimental tests.
