Research on Evacuation Elevator Technology and Performance Optimisation Design for Super High-Rise Buildings
摘要
Abstract
China hosts a vast number of super high-rise buildings,where accidents involving existing structures occur with notable frequency.Evacuation in such buildings is often prolonged and inefficient,underscoring the urgent need to enhance performance through the adoption of evacuation elevators.Although current building codes stipulate the installation of auxiliary evacuation elevators,their actual implementation remains limited,and the supporting technical framework is insufficient.Drawing on a systematic review of evacuation elevator applications nationwide and incorporating findings from a national key R&D programme,this study identifies critical technical requirements and introduces a multi-objective performance optimisation design method aimed at reducing total evacuation time and improving the utilisation efficiency of evacuation modes.The proposed method uses the number of evacuation elevators,the floors served,and the proportion of evacuees assigned to elevators as key design variables,optimising integrated stair-elevator evacuation strategies for super high-rise buildings.Three buildings of different heights were selected as case studies.Compared with stair-only evacuation,total evacuation times for the 572 m,294 m,and 200 m buildings were reduced by 34％,24％,and 38％,respectively.The results demonstrate that the proposed optimisation method provides an effective technical basis for evacuation design in super high-rise buildings,markedly enhancing overall evacuation efficiency and safety.This approach holds significant potential for both the retrofitting of existing structures and the design of new projects.关键词
