Fire Smoke Control and Ventilative Cooling of Atrium in High-Rise Buildings
In a traditional atrium design (i.e., a single high vertical space), natural ventilation (NV) is an attractive design but usually is limited by the fire department. This study proposes a novel NV design to mitigate this conflict, which includes a segmentation slab and ventilation shaft. The segmentation slab divides a high large atrium into upper and lower parts. The ventilation shaft can extract the smoke and maintain the performance of NV for daily use. To examine this ventilation design, a small-scale experiment and numerical simulation were conducted. The results show that this design can simplify the design of the mechanical smoke control system while maintaining the smoke control performance, i.e., thinner smoke layer depth. Furthermore, the ventilation shaft can perform a higher NV rate than the traditional ventilation design. This study can promote the NV application in the high-rise atrium.
