specific example

[0065] The first part: Calculate the optimal proportion of evacuated people by stairs and elevators when each floor is evacuated separately.

[0066] precondition:

[0067] Define the evacuation time of people on this floor via stairs s as:

[0068]

[0069] Among them, W s is the width of the stairs s; C s is the traffic speed of stairs s; t move The time required for the crowd to go to the next floor when there is no congestion, generally takes 16s; is the number of people evacuated from floor f who chooses stairs s, and has:

[0070]

[0071] Among them, N f is the number of people on floor f, is the proportion of people on floor f who choose stair s.

[0072] Define the evacuation time of people on floor f via elevator e as:

[0073]

[0074] Among them, h f is the height of floor f; n e is the load number of elevator e; v e is the average running speed of elevator e; Respectively, the time for people to enter and exit the elevator e; is the time ...

Abstract

The invention discloses a super high-rise building stair elevator collaborative evacuation optimization strategy instant generation algorithm, which relates to the technical field of building evacuation and solves the defect that the efficient emergency evacuation of an existing super high-rise building is difficult to achieve. According to the technical scheme, the method is characterized in thatthe optimal evacuation crowd proportion of the stairs and elevators during independent evacuation of each floor is calculated, and the result serves as an initial input parameter to calculate the optimal evacuation crowd proportion of the stairs and elevators during overall evacuation. According to the super high-rise building stair elevator collaborative evacuation optimization strategy instantgeneration algorithm, the number of people using the stairs and elevators can be reasonably distributed, and the highest evacuation efficiency is achieved.

Description

technical field [0001] The present invention relates to building evacuation technology, in particular to a super high-rise building stair-elevator cooperative evacuation optimization strategy real-time generation algorithm. Background technique [0002] Due to the long vertical evacuation distance and the single evacuation method, the emergency evacuation of super high-rise buildings (buildings with a height greater than 100m) has received extensive attention. Among them, the use of elevators for personnel evacuation in the case of super high-rise building fires is currently recognized as an effective way to improve the efficiency of crowd evacuation. Some landmark super high-rise buildings, including Burj Khalifa, Shanghai Tower, China Zun, Canton Tower, etc., have installed auxiliary evacuation elevators. Therefore, the combination of elevators and stairs has become a way to optimize the evacuation process of super high-rise buildings, and the rationality of the combinati...
