Abstract

The invention relates to a self-resetting central support system of a steel frame with a large clearance, belonging to the field of structural engineering. Each component of the system is processed by the factory, and all are connected and installed by high-strength bolts, which is easy to achieve high requirements for component processing accuracy and quality and rapid assembly, and conforms to the concept of assembled green steel structure; the diagonal bracing system of the present invention is assembled. Anti-buckling Y-shaped support, energy-dissipating elements are installed at the position of the diagonal bracing, which improves the overall stability of the diagonal bracing system and the overall lateral force resistance of the structure. It can meet different structural forms; by adding a new type of combined self-resetting device, the overall bearing capacity of the beam can be improved and the overstress load on the I-beam section caused by the pretension of the cable in the combined self-resetting device can be avoided. The cable pretension enables the structure to control the development of plastic deformation and the accumulation of damage, so that the structure has good seismic performance and reset ability.

Description

technical field [0001] The invention relates to a self-resetting central support system of a steel frame with a large clearance, belonging to the field of structural engineering. Background technique [0002] With the acceleration of the urbanization process, the development of the construction field and the continuous improvement of the technical level, coupled with the impact of environmental pollution and resource waste, the defects of poor environmental protection in the traditional building system are gradually exposed, and the green fabricated steel structure has begun to become a building The main types of systems. Compared with the traditional system, this system has significant advantages in terms of construction quality and construction efficiency. "Building blocks" is a representative construction method, which greatly speeds up the construction speed and saves project funds. Applying it to the design and development of various building systems is the main trend...
