Automatic design method and device for modularized cold-formed thin-walled steel structure

The invention relates to the technical field of automatic design of light steel structures in the building industry, in particular to an automatic design method and device for a modular cold-formed thin-walled steel structure, and the method comprises the following steps: obtaining the number of floors of a to-be-designed building, the seismic fortification intensity and the type of a covering plate of the to-be-designed building; searching the minimum length of the first shear wall from a preset aseismic design simplification calculation table; determining the length of the shear-resistant wall body without the door and window hole as the actual length of the shear-resistant wall; comparing the minimum length of the first anti-shear wall with the actual length of the anti-shear wall; and if the actual length of the shear-resistant wall is larger than the minimum length of the shear-resistant wall, the shear-resistant bearing capacity meets the requirement, the final length of the shear-resistant wall is obta
