“…Chen and Feng proposed a fast flow control algorithm to assign evacuees to different doors by calculating minimum evacuation time (Chen and Feng, 2009). Kang proposed an integer programming model to assign multiple exits to different evacuees to minimize evacuation time in a complex building considering the congestion phenomenon at each exit (Kang et al, 2015). Heuristic algorithms have also been used to solve the evacuation route optimization problem.…”

The number of large public buildings is growing rapidly in function and complexity, which cause the evacuation path in case of fire to be too long and complex increasing the evacuation time. In this paper, a constraint-based design approach is introduced to automatically generate the optimal position of the building evacuation door to minimize the length of the escape route, thus reducing the evacuation time. The position of the evacuation doors is ruled by design specifications and building structures, in this study,

“…Most of the elderly, living in nursing homes, need to use crutches, wheelchairs, or other occupants or firefighters to evacuate, and only a small number of elderly people can evacuate without help [39]. When these special groups are evacuated in high-rise buildings, large-scale and slowmoving elderly people such as those in wheelchairs and using a stretcher tend to block the channel, with serious ramifications for other passengers to evacuate [40][41][42].…”

There were increasing concerns on the possibility and suitability of using elevators for high-rise building evacuation because, through the improvement of the elevator system, the self-evacuation ability of age people is promoted as much as possible in the process of an emergency evacuation. The combined evacuation using both elevators and stairs was put into discussion. However, there was no empirical evidence and numerical simulation on emergency evacuation using both elevators and staircases for aging people in high-rise nursing homes. Therefore, using one case study, this paper simulated the emergency evacuation in a high-rise nursing home using variables such as the distribution of the elderly with different physical conditions, the proportion of the elderly in different physical conditions, the number of the elderly, the number of floors, the number of elevators used, and the priority of the elevator floor. By simulating the evacuation process in various scenarios, the general distribution strategy of high-rise nursing home and the optimal use of the elevator-stair combination during the emergency evacuation were developed. Results show that the elevator-stair combination of evacuation is more effective than using elevators or stairs alone. Increasing the number and speed of elevators can reduce evacuation time. Categorizing elderly people on each floor according to their physical conditions could reduce the evacuation time than randomly distributing them.

“…It is postulated that an effective crowd simulation could converge to form a simulation metric that depicts observable real-world data. As knowledge expands and modeling techniques improve, we will be able to learn more about social forces and the psychological and behavioral science of large crowds [46][47][48]. The proposed kinetic contour wall may show an improvement over the other architectural configurations because curved geometrical spaces reduce the shear-stress vector.…”

Adaptive Kinetic Architecture and Collective Behavior: A Dynamic Analysis for Emergency Evacuation

et al. 2019

View full text Add to dashboard Cite

Adaptive kinetic architecture has emerged from a need for innovative designs that adapt to the environment and changing needs of the occupants. Architectural design and modes of egress are critical in an emergency. Flocking describes a certain collective behavior where agents are brought together in groups and move as a cohesive unit from place to place. Collective behavior may be observed in microscopic as well as macroscopic environments. Crowd modeling incorporates the study of human behavior, mathematical modeling, and molecular or fluid dynamics. The simulation of agents and their movement in the built environment is beneficial for design professionals, scientists, and engineers. Human behavior in panic situations is notably similar to fluids and molecules. The objective of this research was to evaluate the movement of agents in buildings using discrete dynamic simulation. We used a novel discrete molecular dynamics technique to simulate the evacuation of agents in panic situations. Various adaptive geometric configurations were analyzed for improved crowd flow. Kinetic walls were modeled in order to evaluate design optimization as it relates to rates of egression. This research proposes the use of kinetic walls to improve safety and efficiency during an emergency evacuation. Adaptive geometric configurations show improvements over the conventional design framework.
