CPI win REI is the Namirial solution that we offer to you to verify analytically the fire resistance of structures according to the Euro-codes. The structures are verified using nominal fire curves and subjecting the structures in fire situations as close to reality. With REI you can verify the fire resistance of elements in reinforced and/or prestressed concrete (REI ca-cap), steel structures (REI Steel), bearing and non-bearing walls (Rei Walls), and of wood structures (REI Wood).
CPI win REI performs the thermal analysis and calculates the strenght of the structures. To know the temperatures reached by the element, we must set the fronts of fire of the element for which you can specify whether it is directly exposed to fire or not. Setting the exposure time and the verification interval, the program performs the thermal analysis of the structure. Important in this stage is the choice of the curve that can be of three different kind:
- Standard (curves present in the program)
- Parametric (according to the CNR method or Wickstrom curve according
- Natural (curve obtained through our FSE program)
All calculation data are reported in a complete and customizable technical report.
CPI win REI Wood verify rectangular or circular wood structures, considering the size, the type of wood which it is composed, the exposure to the fire, the paint protection or the protective cover and considering tapering, carvings and constraints. The calculation is performed according to the Euro-codes 5 and verify the resistance to the stresses set in following the consumption of wood, called charring rate.
CPI win Rei ca-cap, Steel, Walls and Wood produce comprehensive technical reports fully customizable.
