Structural Safety Monitoring during Retrofit of Shanghai Expo Puxi Entertainment Hall
Shanghai Expo Puxi Entertainment Hall is reconstructed based on existing workshop building.To meet new function requirements of the hall, a structural column is removed and replaced with a jacking beam.A structural safety monitoring system is proposed and applied to evaluate the real-time structural state and ensure the structural safety.Vibrating wire sensors and FBG sensors are installed to monitor the stress of member of the space truss structure; ForesightTM series DSTS (Distributed Strain and Temperature Sensors) is installed to monitor the stress of the jacking beam.Results show that the structural safety monitoring system works stably.The safety monitoring system reflects the real-time behavior of the structure and controls the structural reconstruction safety effectively.
