杭州亚运会主体育场结构健康监测与分析OA北大核心CSTPCD

In order to satisfy the health monitoring and analysis needs of the large-span spatial structure of the main stadium of the Hangzhou Asian Games,firstly,based on the structural characteristics and service environment of these kind of buildings,a multi-parameter,modular wireless sensor network system was customized,and an intelligent and expandable tree-type networking strategy anda time synchronization collection mechanism were developed to satisfy the hardware technical requirements of large-span spatial structures.Secondly,based on the Internet platform,the remote monitoring and structural response analysis of the structure were realized to reflect the performance status of the structure in real time,and the long-term stable work of the system verified its stability and durability.Finally,the monitoring data of various parameters of the stadium not only reflected the internal force change of key components of the structure during the construction process,but also the basic characteristics of environmental loads such as wind load,vibration and temperature field of the structure during the operation period.The monitoring data also indicate that the long-term stress of the structure is relatively stable and is mainly affected by the change of temperature,which provides scientific guidance for the construction,operation and management of the stadium structure.
