The wood products industry is growing, as evidenced by the desire to build larger and taller buildings with timber and the start-up of new manufacturers. Despite the benefits of timber, projects are still experiencing approval resistance, namely when performance-based design (PBD), i.e., alternative solutions, are proposed to demonstrate code compliance. To gain approval, testing is often required to confirm the performance of a given product or design. While large-scale testing can always be performed, it tends to be very costly and time consuming, and can be argued to be valid only for the scenarios being tested. Fortunately, greater knowledge in fire safety engineering now allows for much more advanced/sophisticated fire modelling techniques. These techniques are gaining popularity in lieu of large-scale testing to extrapolate results and support PBD, provided the input parameters and results are verified and validated appropriately. This InfoNote summarizes some of FPInnovations activities related to advanced fire modeling in support of PBD.
