| With the development of the building technology in China,the spatial structure of large public buildings is becoming more and more complex,resulting in an increasing of evacuation distance,thus the difficulty of evacuation will increase in case of emergency.The traditional evacuation design way is based on prescriptive rules which provides same design parameters for different forms of buildings,but the spatial layout of different buildings varies,buildings that only meet specifications are not the safest.Therefore,this thesis introduces a constraint-based design method to generate the optimal position of the evacuation doors to minimize the evacuation path of the entire building.Based on the building performance design theory,this thesis summarizes the key indicators for measuring building performance,and introduces the key steps in the optimization design of building performance.Then this thesis gives a summary of the influencing factors of personnel evacuation performance and explores the impact of evacuation exit layout on evacuation performance.This thesis studies the characteristics of evacuation routes for large public buildings and model evacuation networks.Next,this thesis proposes a constraint-based design approach to automatically generate the optimal position of the evacuation doors to minimize evacuation time.The constraint-based model in this thesis includes design constraints and space constraints.A case study of Hubei Museum of Science and Technology indicates that the evacuation door layout generated by our approach outperforms the original layout.Compared with the existing work,approach in this thesis avoids repeated modification of the design drawings and has significantly shortened the evacuation time by generating door positions.The method of this thesis can provide new ideas for evacuation performance design,and can also provide efficient new tools for the work of building evacuation design. |
