TR9 software is a model to extrapolate the results of a fire resistance test on a light timber framed wall or floor/ceiling, to a greater height or span and/or loading, which can be used in the design of light timber framed walls and floor/ceilings for fire resistance, where a prototype system has a successful fire resistance test result.
TR9 is based on BRANZ Technical Recommendation No. 9
This Windows based software package has been developed from the version 1.0 software (Collier 1996) which originated from the findings of a research project, "Design of loadbearing light timber framed wall for fire resistance" (Collier, 1991a, 1991b and 1992), conducted by BRANZ.
Subject to the availability of suitable fire resistance test results, this programme can be used as a tool in the design of timber buildings which are required to have fire separations, such as fire-rated walls and floors.
