Abstract

In order to explore design rationality of landings at egress door of kindergartens and to fill in the blank of children's evacuation behavior data in this part, evacuation drills on landings at egress doors in two fulltime six-classroom kindergartens were conducted and evacuation behavioral data at landings of 4 different designs were obtained. Then, their walking speed, evacuation time and flow rate were analyzed and compared. The results show that walking speed of children aged 4-6 on non-smooth steps is between 0. 52-0. 98 m/ s. Design difference of landings has obvious influence on children's evacuation behavior and evacuation effect, and double-sided landings can increase flow rate by 1. 8 times. © 2019 China Safety Science Journal
