Fire dynamics in mass timber compartments

Since Engineered Wood Products (EWPs) have entered the building industry as structural elements, several fire safety concerns arisen, especially for high-rise structures. The combustible nature of timber suggests that current models and correlations compartment dynamics might not apply to compartments with boundaries, due increased fuel load its redistribution across compartment. In order fill this knowledge gap, 24 medium-scale been carried out characterise when members are present. This experimental campaign provides data about gas-phase temperatures, flow fields at opening, burning behaviour contribution total heat release rate. is then compared Thomas Heselden (1972) [1] framework predicts development in conventional compartments. comparison highlights limitations framework, subsequent analysis proposes changes include effect elements. It concluded gas velocities increase amount present Therefore, transitions a new regime where gases do enough time mix react inside compartment, temperatures decrease horizontal opening increase.
