Abstract

The invention relates to a large-headroom restorable-function steel-framed centrally-braced system and belongs to the field of structural engineering. All components of the system herein are processedin a factory; connecting and mounting are performed completely through high-strength bolts; the high requirement on component processing precision and quality is easy to meet, quick assembly is easyto implement, and the idea of prefabricated green steel structures is satisfied. A diagonally braced system herein is prefabricated anti-buckling Y-shaped bracing; energy-dissipating elements are arranged at diagonal braces; therefore, stability of the diagonally braced system and overall lateral load resistance of structure are improved. Door opening may be arranged in the position where the bracing is set, so that the design form is more flexible, and different structural forms are satisfied. A novel self-resetting device is added, overall bearing capacity of a beam can be improved, and extra stress load upon an I-beam segment due to rope pre-tension of the self-resetting device can be avoided. By applying prestress to prestressed cables, development of plastic deformation and damage accumulation can be controlled via the system herein; the system has good aseismic performance and restoring capacity.

Description

technical field [0001] The invention relates to a center support system of a recoverable functional 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 mai...
