The purpose of this study is to examine the influence of remoteness between exit stairways on evacuation
performance. Firstly, we reviewed the design regulations of the U.S., the U.K., and South Korea, in relation to remoteness
between Exit stairways. Secondly, evacuation simulation was implemented, in order to evaluate the adequacy of each
standard. Eight tall buildings in South Korea were selected for the simulation. Evacuation performance was assessed for
different remote distances between Exit stairways. Lastly, this research analyses the evacuation simulation data statistically
in relation to the effect of remoteness on evacuation time. We found that as the distance between two exit stairways
increases, the total evacuation time and average evacuation time for evacuees decreases. There was no statistical influence
between the maximum travel distance of the evacuee and the remoteness between two exit stairways, but there was a
significant effect on the average travel distance of the evacuees. In addition, the results from the optimal point showed that
the L_ratio had the highest evacuation time at 0.44, while the D_ratio had the highest evacuation time at 0.38. |
