Abstract

The invention relates to a large-net-clearance self-resetting steel frame center bracing system, and belongs to the field of structural engineering. All components of the system are machined by a factory and mounted in a connected manner by the aid of high-strength bolts, high requirements for component machining precision and quality can be easily met, rapid assembly is easily realized, and the system conforms to the concept of assembled green steel structures. The diagonal bracing system is an assembled buckling-restrained Y-shaped brace, an energy dissipation element is arranged at a diagonal bracing position, the overall stability and structural lateral load resistance of the diagonal bracing system are improved, a door opening can be formed in the position of the brace, so that the design form is more flexible, and different structural forms can be met. By adding a novel combined self-resetting device, the overall bearing capacity of a beam can be improved, over-stress load applied to an I-beam section caused by pulling cable pretension in the combined self-resetting device can be avoided, pre-stressed cable pretension is applied, so that the structure can control developmentof plastic deformation and damage accumulation, and the structure has good anti-seismic property and resetting capacity.

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...
