Section steel-square steel pipe combined buckling restrained brace
The invention provides a section steel-square steel pipe combined buckling restrained brace. The section steel-square steel pipe combined buckling restrained brace comprises a core stress component, an outer restraining component and a positioning pin; the core stress component is formed by connecting a plurality of section steel energy dissipation sections, a middle limiting section, a pluralityof square steel pipe elastic sections and two end connecting sections coaxially in the longitudinal direction, the outer restraining component is a square steel pipe, and the core stress component islocated inside the outer restraining component; and the periphery of the middle limiting section and the peripheries of the square steel pipe elastic sections of the core stress component are tightlyattached to the inner side of the outer restraining component, and gaps exist between the section steel energy dissipation sections and the outer restraining component. According to the section steel-square steel pipe combined buckling restrained brace, torsional deformation of the square steel pipe elastic sections can be effectively limited, so that overall torsional deformation of the core stress component is limited, surface strain of the section steel energy dissipation sections of the core stress component is reduced, and the low-cycle fatigue performance of the buckling restrained braceis enhanced; and meanwhile, profile steel and the square steel pipe are common materials in a construction site, can be cut and installed on site according to use requirements, and are simple in structure, light in self-weight, convenient to use and low in cost.
本发明提供一种型钢‑方钢管组合式屈曲约束支撑，包括核心受力部件、外约束部件和定位销钉。所述核心受力部件由多个型钢消能段、中间限位段、多个方钢管弹性段和两端连接段沿纵向同轴线连接组成，外约束部件为方钢管，核心受力部件位于外约束部件内部，核心受力部件的中间限位段、方钢管弹性段四周与外约束部件内侧紧贴。型钢消能段与外约束部件之间存在空隙。本发明可有效限制方钢管弹性段的扭转变形，从而限制核心受力部件整体扭转变形，降低核心受力部件型钢消能段的表面应变，增强屈曲约束支撑的低周疲劳性能。同时型钢及方形钢管均为施工场地常用材料，可根据使用需求进行现场切割和安装，结构简单，自重轻巧，使用方便，成本低廉。
