Fabricated steel frame-buckling-restrained brace system
The invention provides an assembly type steel frame-buckling-restrained brace system which comprises an embedded steel frame and a buckling-restrained brace component, the embedded steel frame and the buckling-restrained brace component are connected through bolts and gusset plates, and stiffening plates are arranged at the connecting positions of the embedded steel frame; when the height-span ratio of the embedded steel frame is about 1 and 0.5 respectively, the buckling-restrained brace members respectively adopt a central frame system and a herringbone frame system; linear connecting steel plates are arranged on the outer side of the embedded steel frame and the inner sides of beams and columns of an original frame structure and are connected in a welding or bolting mode. The lateral stiffness resistance and lateral bearing capacity of the structure can be improved, the earthquake energy dissipation capacity of a building can be enhanced, damage to a main body structure is reduced, meanwhile, the prefabricated construction requirement is met, the construction period is shortened, the cost is saved, and high-degree industrial production is facilitated.
本发明提供一种装配式钢框架‑防屈曲支撑体系，包括内嵌钢框架和防屈曲支撑构件，内嵌钢框架与防屈曲支撑构件通过螺栓和节点板连接，内嵌钢框架上在连接处设有加劲板；内嵌钢框架高跨比分别约等于1和0.5时，防屈曲支撑构件分别采用中心和人字形布置框架体系；内嵌钢框架外侧和原有框架结构梁与柱内侧均设有一字形连接钢板，采用焊接或栓接连接。本发明可以提高结构的抗侧刚度和侧向承载能力并且可以增强建筑地震耗能能力，减轻主体结构的破坏和损伤，同时还符合装配化施工要求，节省工期，节约成本，便于进行高度工业化生产。
