Abstract
The objective of this research was to investigate performance-based fire safety design in satisfying the tenability criteria of high-rise buildings with an occupancy load of greater than 1000 people per stairwell. This was completed through a sensitivity analysis of a 20-story high-rise building model using the Fire Dynamics Simulator for modeling a range of fire scenario. A total of 16 simulations were analyzed, with varying building parameters such as room geometry, sprinkler type, detection devices, and egress door configuration. The building was designed to comply with the New Zealand Verification Method (C/VM2). The acceptance criteria for visibility, toxicity, and thermal effects, were taken from the New Zealand Building Code (NZBC). The results for all simulations showed that the visibility requirements in the stairwell were the controlling tenability criteria when compared to the carbon monoxide and thermal effects. The results demonstrate the need for smoke detectors in conjunction with sprinklers in high-rise buildings.
