Vibration Comfort Analysis of Large-span Roof and Construction Technology of Pipe Truss Structure
The roof of a middle school wind and rain playground is a large-span inverted triangular space pipe truss structure,which has both motion function and heavy load.Therefore,it is necessary to analyze the resonance technology of the roof for the wind and rain playground in the detailed design stage to ensure the comfort of the playground movement personnel and the space under the roof is not disturbed.The measurement and monitoring technology,side assembly and hoisting construction technology of large-span inverted triangular space pipe truss are studied to achieve the design effect.The results show that the vertical natural frequency and maximum acceleration of the structure meet the requirements through resonance analysis.The hoisting problem is solved by temporary support,arching and single integral hoisting of truck crane,and the design accuracy is achieved.Through accurate measurement and monitoring,the quality and safety of the processing and installation process are guaranteed.
