Floor haunching is usually used for a large plate structure, and has the advantages of fully utilizing material performance according to stress requirements and improving torsional rigidity and bending rigidity of a section.
The floor haunching design method based on the Revit platform, which is common in the industry at present, comprises the following steps: in the Revit platform, structural engineers manually and repeatedly draw at positions meeting structural design rules (including national and industry general design standards and interior design standards in China instead of China and drawing rules) by judging the arrangement of the existing structural beams and plates based on a three-dimensional model.
The technical scheme has the defects that: 1. manual drawing is easy to make mistakes, and special manpower is required for correction and modification; 2. the repeated workload is large and the efficiency is low.
