Research on Monitoring Technology of Long-Span Prestressed Concrete Construction

The author performs simulation analysis on construction process of roofing prestressed concrete beam of comprehensive service center in Beijing Institute of Civil Engineering and Architecture by finite element software Midas/Gen, so as to determine the monitoring programme according to the analysis results. The monitoring results indicate that the structure is safe; the theoretical value of simulation analysis is well matched with actual monitoring value, which means that the finite element model of construction process of roofing prestressed concrete beam is correct, the simulation method is feasible and the construction process is reasonable. It has important reference value for construction and monitoring of subsequent similar projects.
