Technical Field
The invention relates to the field of construction of mathematical models of steel structure correcting force, in particular to a construction method of a mathematical model of steel structure correcting force.
Background
Among the modern building base materials, steel members and cement members are the two most common types of building base materials, wherein the steel members are widely applied to various large buildings due to high strength and good processability.
Before building construction, stress calculation is usually performed on building materials for construction, and since calculating the bearing capacity of each building material through the stress calculation is a theoretical basis for whether a building can be built, a building designer usually performs systematic and complete calculation on the shape, size, material, and the like of the building when designing the building.
However, even if the architects make systematic and complete calculations at the time of design, when actually welding the H-section steel, the main deformation of the steel structure is the lateral bending due to flame-cut blanking, the angular deformation and bending deformation of the flange plate due to welding, and the distortion and wave deformation due to improper welding procedures. When the welded beam string with the box-shaped section is manufactured, main deformation includes lateral bending caused by flame cutting and blanking, and distortion and deformation caused by welding. If the deformation problem of the components in the manufacturing process is not corrected, the overall geometrical size of the structure is influenced, and the safety and reliability of engineering are reduced. In order to ensure the engineering quality and the construction precision, the deformation of the correcting component is a construction difficulty in the manufacturing stage of the steel structure engineering.
Flame straightening is generally adopted for straightening components under normal conditions, and the principle of flame straightening is to utilize the contraction force of steel materials after being heated and cooled to offset the stress generated by welding.
In the actual production process, flame straightening usually needs a technician with abundant experience, and different technicians have familiar technique habits and technical flaws, so that the unified mathematical model is difficult to meet the same flame straightening requirements of different technicians.
