Abstract

The invention relates to a self-resetting steel frame central support system with a large clearance and a flange, belonging to the field of structural engineering. The diagonal bracing system of the present invention is an assembled anti-buckling Y-shaped support, and an energy-dissipating element is arranged 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, and can be installed The door opening makes the design form more flexible and 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 cable pretension in the combined self-resetting device can be avoided. By applying the prestressed cable pretension, the structure It can control the development of plastic deformation and the accumulation of damage, so that the structure has good seismic performance and reset ability. Each component of the device is processed by the factory, and all are connected and installed by high-strength bolts, which is easy to realize the high requirements of component processing accuracy and quality and fast assembly.

Description

Technical field[0001]The invention relates to a self-resetting steel frame central support system with large clearance and flanges, which belongs 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 disadvantages 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 type of system. 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 in ...
