With mass timber structural systems being increasingly used in tall and large buildings, the Fire Protection Research Foundation (FPRF) initiated a series of research projects to help address fire safety challenges of tall mass timber buildings. Previously completed projects include a review of mass timber building fire performance, identification and prioritization of research needs, and experimental and modelling works to quantify the contribution of cross laminated timber (CLT) building elements to compartment fires. These projects focused on fire safety and protection of occupants, fire fighters, and property during a fire. A topic that has not been well addressed is the repair of mass timber after a fire event. Tall mass timber buildings are expected to resist significant structural failure or collapse during and after a fire. However, technical information and guidance on how to repair and recertify a mass timber structure after a fire are lacking. Therefore, the Fire Protection Research Foundation initiated this research program is to develop guidance on repair and recertification of mass timber structures after a fire. The objective of this phase of the project was to develop a research plan for future research projects to help bridge the gap in knowledge needed to enable repair and recertification of a mass timber structure after a fire.
