Deformation Stability of Protective Scaffolding Based on MIDAS:Taking the Shilong Sima River Bridge as an Example
Based on MIDAS Civil software,the model of protective scaffolding of beam-column bridge was established,and the working state of the protective scaffolding was simulated under four different loads including dead weight,temperature load,live load and dead load,the strength,deformation and stability were analyzed,and the practicability of the beam-column support scheme applied to the protective scaffolding was verified.The results show that the beam-column type protective scaffolding can provide stability protection for the bridge in time,and the strength of the steel tubular column,beam and distribution beam can meet the requirements The overall stability of the support and the local stability of the steel pipe column can meet the requirements.According to the research results,the corresponding optimization measures and suggestions are put forward to provide theoretical support and practical guidance for the design,construction and maintenance of the bridge protective scaffolding.
