Study and practice on BIM design method of special-shaped steel formwork for flow channel

In order to improve the design quality and efficiency of special-shaped steel formwork for Flow Channel, BIM parametric design method is studied. Firstly, according to the shape design results of the flow channel, we sort out the inner wall parameters of the steel formwork, write the parametric modeling code, and drive the automatic modeling of the steel formwork shell. Then, according to the results of the reinforcing design of the steel formwork structure, we divide the outer surface of the shell into physical and chemical UV grids, and the isotropic reinforcing ribs are created adaptively. BIM parametric design has the advantages of visualization, automation, and simulation, and its universality and accuracy are significantly improved compared with 2D design. The BIM model can also be applied to finite element calculation to improve the quality and efficiency of complex structural design.
