Research On Building Evacuation Ability Based On Revit Platform

With the progress of the economic development era,the urban population has grown rapidly.The construction industry to meet people's work and life has also developed rapidly.With the rise of various types of buildings,building safety issues have also received increasing attention.Especially the problem of evacuation ability of the building itself.The evacuation capacity of the building involves various constraints such as the internal structure of the building and the design of the escape route.The traditional evacuation and emergency plan exercises cannot directly demonstrate the process of rescue and escape.The emergence of BIM(Building Information Modeling)has brought about tremendous changes in the production structure and development model of the construction industry.Through the building information model,people can visually see the basic structure of the building and understand the basic information of the building.It also provides detailed information on key locations related to evacuation of buildings and provides technical support for emergency evacuation and emergency response planning.This thesis starts with the research status of building evacuation ability,the status of secondary development of Revit and the analysis of BIM technology.Apply Visual Studio 2013 development tools,use C# programming language,combine Revit software for secondary development,and apply BIM technology to the field of building evacuation capability simulation research.The core content of the paper program technology mainly involves the extraction of key information in the BIM building model through the secondary development technology of Revit software,and the extracted building information as the qualification condition for the evacuation ability evaluation of the building itself.Through the secondary development of the Revit platform,the problem of assessing the evacuation ability of the building due to insufficient building information data was solved.The evacuation path optimization in the simulation process uses the ant colony algorithm for shortest path search.Through the simulation software built by the secondary development,and with the characteristics of the 3D visualization of the BIM technology,the building evacuation capability is simulated and the simulation results are directly output through the program.The simulation process and the comparative analysis results of the paper provide reference value for the study of building evacuation ability in the future,and provide reference for emergency evacuation and emergency rescue of building fire.
