Combining the practical experience and based on analysis of the design characteristics oftemporary structures, this paper adopts digital modeling technology. By establishing functional graphicobjects in the graphics system, including concrete main beams, formworks, square timbers, smalltransverse distribution beams, main load⁃bearing beams, large transverse distribution beams, steel pipecolumns, and strip foundations, a design model for beam⁃column formwork support is created. Throughoperation on these functional graphic objects, mechanical calculation results of beam⁃column formworksupport can be conveniently queried, while automatically generating Midas command streams for 3Dmechanical calculations, construction detail drawings of beam⁃column formwork support, and engineeringquantity tables for design schemes. This realizes simplified, standardized, and highly efficient design ofbeam⁃column formwork support, with good adaptability. It is conducive to repeated comparison andselection of beam⁃column formwork support in bridge construction, as well as potential excavation andefficiency improvement in construction projects.
