Abstract

Taking the construction project of the National Cybersecurity Talents and Innovation Base as an example, this paper studies the construction technology of freeform surface spatial bending-torsion steel structure based on structural design model transformation, including the parametric modeling of deepening design model, computer-aided bending and torsion frame production, flexible docking in the bending-torsion combination unit, and welding stress deformation, in hope to provide reference for similar projects in the future.
