The Effect of Plan Corner Shapes on the Spread Speed of Fire in High-Rise Buildings

This study investigates the impact of plan corner shapes on the propagation rate of fire in high-rise buildings. Employing the PyroSim fire simulation program, a systematic modeling approach was adopted to simulate fire spread in a 12-storey building with varying plan corner shapes. The findings reveal that plan corners exhibiting straight configurations devoid of protrusions or recesses exhibit a reduced risk of fire spread when contrasted with irregular shapes. Consequently, we propose the integration of regular plan shapes lacking protrusions or recesses in the design of high-rise buildings to effectively minimize the rate of fire spread. This research contribution facilitates the selection of an optimal design alternative with respect to the velocity at which fire propagates.
