Effects of Spandrel Heights on Leapfrog Effect in Tall Buildings
Along with the increasing number of tall buildings, more attention is paid to the façade which has a significant influence on the aesthetic appearance of the building. Therefore, architects are strict in their design to create a unique building. Façade fire is a disastrous hazard that can spread rapidly throughout the building. Leapfrog is a type of fire spread that occurs due to excessive heat from flames projecting from the lower floor to the floor above. Code provisions are available to control leapfrog by changing spandrel heights, but in some cases, it is not feasible due to architectural requirements. A performance-based method was used to study the vertical fire spread issues due to leapfrog using a numerical model. Results have shown that limited ventilation with proper compartmentation under the automatic active fire protection provides considerable fire safety avoiding flames ejecting from the broken glass or glasses in glass curtainwall facades.
