Design fire curves for BVG, Berlin

IFAB was con­tract­ed by the Berlin pub­lic trans­port sys­tem (BVG) to cre­ate a design fire curve for the metro vehi­cle types H and HK (large and small pro­file). This devel­oped curve is used as a design fire curve for the smoke and evac­u­a­tion sim­u­la­tions in all BVG sta­tions in the future. The design fire curve is based on 4 dif­fer­ent pos­si­ble sce­nar­ios that all were sim­u­lat­ed. The results of the most suit­able sce­nario were cho­sen in order to cre­ate the final design curve.
