Slide 4Smoke Management Evacuation Access for Fire Brigade Architecture Mechanical Engineering HVAC frameworks Hydraulic Systems Civil Engineering Detection & Alarm Smoke Management Suppression & Control Fire Resistance Evacuation Access for F.B. Security Fire Safety Engineering Fire Resistance Structures
Slide 5Fire Safety Strategies Prescriptive Design Performance Based Design
Slide 6Life Safety Compartmentation Structure Response
Slide 7Life Safety Common Sense Compartmentation Locate According to producers Specifications Specify According to Manufacturers Standard Test Data Structure Response Define as indicated by basic guidelines (Common Sense) Common Sense Common Sense
Slide 8Can similar principles be connected?
Slide 9Charles de Gaulle Airport, Paris The Dome London Intercontinental Hotel, Shanghai
Slide 11Compliance Limited to customary structures Conventional is less and less regular Construction has developed speedier than codes Construction has advanced quicker than our ability to prepare powers/engineers/fire benefit Codes must be utilized as a device for the skillful expert
Slide 12Summary Fire Safety Engineering is a mind boggling field that connects with every single other train in the development procedure Codes and Standards (exemplary practices) are suitable just for straightforward structures – complex structures require more elevated amount designing Fire Safety Engineering is a critical calling in the development procedure!
Slide 13Fire Safety Strategies Evacuation Detection Alarm Displacement far from the fire Crowd administration Compartmentation Slows fire development Minimizes smoke spread Response Automatic (fire concealment) External Internal Structural Integrity

Slide 17Allen Lambert Gallery (Canada)
Slide 18Unprotected structure High Ceilings Delayed discovery Delayed sprinkler Activation Smoke Management
Slide 19Egress Problem
Slide 20Refurbishment of Historical Monument Combined Construction Methods (Modern-Classic) Interconnected Multiple Uses Complex utilization of materials (plastic, steel, stone, and so on.)
Slide 21How are these issues tended to Can not be tended to by method for codes and gauges They are tended to by a mix of codes & measures and also investigative instruments The procedure requires a mind boggling endorsements handle where everybody included must be equipped
Slide 22A Detailed Analysis Heron Tower Kohn Pedersen Fox 80 Story Building in London Formed of numerous 4 story "towns" Arup: Fire Engineering
Slide 23Key Issues How Would a 4 Story Fire influence: The basic execution of the building? Departure? Fire Detection & Suppression?
Slide 24The Fire 4 Story Atrium Transforms the Fire None of the customary strategies can address the one of a kind nature of the Fire should be demonstrated Detection, Suppression and Structure should be tried against the genuine fire
Slide 25Modeling of the Fire
Slide 26What does the Engineer need to know? What does a designer need to know to have the capacity to lead a satisfactory CFD investigation of this fire? What does a designer need to know to have the capacity to exchange the fire data to test Detection, Suppression and Structure?
