BIM technology-based super-thick bottom plate steel bar supporting system design optimization system

The invention discloses a BIM (Building Information Modeling) technology-based ultra-thick bottom plate steel bar supporting system design optimization system, which comprises the following steps of:1) establishing an ultra-thick bottom plate BIM model based on a project construction CAD (Computer-Aided Design) drawing, and arranging steel bars of an ultra-thick bottom plate; 2) determining materials, specifications and connection modes of cross beams and stand columns which are made of steel materials and form a steel bar supporting system, calculating mechanical properties of the steel materials and safety parameters of connecting pieces, arranging a temporary steel bar supporting system between upper-layer steel bars and lower-layer steel bars of the super-thick bottom plate, and performing safety checking calculation; and (3) calculating the steel bar supporting system which meets the safety requirement through mechanical calculation and has the minimum steel consumption. The system can efficiently, quick
