Abstract

The invention relates to a fabricated type self-resetting frame system capable of recovering functions, and belongs to the field of structural engineering. The fabricated type self-resetting frame system is composed of two square steel columns with cantilever beam sections, an I-shaped beam section, a group of self-resetting devices and two groups of connecting devices. According to the fabricatedtype self-resetting frame system capable of recovering the functions, welding parts of the connecting devices are finished in a factory, the welding precision and quality are easy to control, and theconstruction speed and quality are improved; lower flange outer covering plates are arranged in an outer covering plate mode, can be used as supports of the beam sections in the installing process and have good performance visibility and replacement decidability; the self-resetting devices can ensure a predetermined performance design purpose of the capacity of structural earthquake energy dissipation and reduces the post-earthquake repairing cost; and through the targeted design, the damage position of a structure occurs to energy dissipation components such as high-strength bolts and connecting plates which are easy to replace under the action of earthquake loads, post-earthquake repairing is convenient, and the fabricated type self-resetting frame system is suitable for the developmentrequirements of a fabricated steel structure capable of recovering the functions.

Description

technical field [0001] This patent relates to an assembled self-resetting frame system with recoverable functions, which belongs to the technical 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...
