TR8 software is a model to predict the fire resistance of concrete slabs and floor systems, and can be used for the design of reinforced or prestressed concrete floor systems when required to have fire resistance.
TR8 is based on BRANZ Technical Recommendation No. 8 - Method for Fire Engineering Design of Structural Concrete Beams and Floor Systems, which you should use to gain an understanding of the basis for the software. BRANZ Technical Recommendation No. 8 is referenced by NZS 3101 as an acceptable calculation method for determining the fire resistance of concrete floor systems. The underlying procedure applies structural engineering principles and material properties at elevated temperature to the calculation of the fire resistance of reinforced or prestressed concrete floor systems.
TR8 applies to floor systems:
