Research on the Ancient Architectural Heritage Protection Model of the Structure of Feiyun Tower Based on BIM
Feiyun Tower is an ancient architectural heritage with profound history and culture,and the ma-intenance of its structural integrity is crucial for cultural inheritance.The study adopts BIM technology to monitor and analyze the structural health status,providing new methods for the protection and maintenance of ancient buildings.The analysis results show that the daily average change rate of the monitoring truss is as high as 19.173%,and the abnormal monitoring value reaches-43.16.The daily average change rate of the mortise and tenon connection and the foundation are-15.902%and-20.041%respectively,but the abnormal moni-toring values are-46.24 and-23.08.For beams and columns,the abnormal daily average change rates are-1.792%and 3.594%respectively.The abnormal monitoring value for beams is 17.33 and for columns is-51.09.The abnormal daily monitoring value of the roof is-62.73,which is the highest among all monitoring locations,indicating that the roof may be subjected to the most severe stress or damage.From this,it can be seen that the model provides early warning for the structural problems of Feiyun Tower,points out the key areas for maintenance and monitoring,provides a basis for formulating targeted maintenance strategies,and provides feasible references for the structural health monitoring of other ancient buildings.
