Building Safety and Resilience

image1
With intelligent facilities in tall buildings, traditional aspects of building safety such as structural strength and fire resistance must also include newer concerns, such as interference of lightning bolts with electrical and electronic systems. The structural response to fire is simulated to facilitate an understanding of the progressive collapse mechanisms of tall buildings in large fires that may spread over multiple floors.
