Research On Wind Resistance Monitoring System Of Building Based On BIM Technology

Typhoon measurement is one of the ways to study the wind resistance of high-rise buildings.At present,the measurement and data processing of typhoon are less connected with the building entity,and basically stay in the two-dimensional space;The efficiency of data transmission is low,and the degree of visualization of data transmission is not enough;The security degree of data is not enough,and the storage of big data is difficult;The data processing needs to be achieved through switching among multiple softwares,with very low integration,The comparison of many typhoon data is difficult.But with the development of the standard weaving and building information technology,the utilization of the measured typhoon data will be visualized,three-dimensional and efficient.As a new technology of the whole life cycle of the building,BIM-(Building Information Modeling)technology not only is multi-functional integrating design,construction and operation,but also has the characteristics of being visualiz,open,highly efficient and widely applied.BIM technology is relies on the powerful processing function of the computer to process the digital information of the building.In order to adapt to the market demand,a large number of BIM software developers provide the API interface,which can be used to supplement the function based on the basis of BIM to meet the needs of individual or enterprise users.In order to address the above mentioned issues,this paper,for the first time creatively combines wind resistance of building structure and BIM technology.Taking Revit Autodesk Revit of BIM software,which has a high market share,as the development platform,we have developed a high-rise building wind database management system.First,the first half of this paper introduces the concept of BIM technology,its current development,both domestically and abroad,and the development of structure resistance to wind.It mainly introduces that the utilization of BIM technology in the whole life cycle of the building and the development status of the research on the wind resistance of the building,and summarizes the processing means of the measured typhoon data in the building structure.Secondly,we have organized and introduced the theoretical knowledge of Secondary Development on the Autodesk Revit in this papper,including the establishment of the 3D model of the architecture structure,second,the API connection theory knowledge of the Autodesk Revit and the application of the API interface,third,the development program language of Autodesk Revit,the secondary development platform and the database theoretical knowledge,and fourth,a whole set of development proceses based on Autodesk Revit.Thirdly,according to the applicational characteristics of the architecture wind resistance theory and the BIM technology theory,the measured data of wind resistance of the building structure are bound to the model,becoming a part of the building information model.The model is related to the typhoon data one by one,avoiding the complex naming of data file.We have designed and developed the functions of the building wind database management system based on Revit,and have successfully developed the functions of user login(protecting data security),building basic information storage,wind data storage,wind data query,wind data processing,typhoon track inquiry,BIM model visualization,the dynamic display and data collection of BIM module,and so on.Finally,the wind data is collected dynamically based on the BIM model.The wind data processing system is used to process the typhoon data,and the related results and the changes of the BIM model are obtained and compared with the traditional data processing methods,The wind data processing based on the BIM model is obtained.With higher efficiencies,safety and level,degree of visualization,and computational accuracy is consistent,meet the analysis requirements.
