FRP (Fiber Reinforce Plastic) metal combined buckling-restrained brace and assembling method thereof
The invention provides an FRP metal combined buckling-restrained brace and an assembling method thereof, and the FRP metal combined buckling-restrained brace comprises a metal core material, the cross section of the metal core material is of a biaxial symmetry structure; the restraining body is used for restraining the metal core material and is an FRP pultruded profile, and a restraining cavity matched with the shape of the cross section of the metal core material is formed in the FRP pultruded profile in a full-length mode; the FRP pultrusion profile is sleeved with the metal sleeve, the inner wall of the metal sleeve is attached to the outer wall of the FRP pultrusion profile, and limiting pieces used for limiting movement of the FRP pultrusion profile are fixed to the two ends of the metal sleeve. Under the condition of guaranteeing the buckling constraint effect, the self weight can be greatly reduced, the time consumption of concrete pouring and curing is avoided, and the combination form that the FRP pultrusion profile is sleeved with the metal sleeve facilitates fireproof protection of the component, facilitates engineering project application and achieves the energy dissipation and shock absorption effects.
本发明提供了一种FRP金属组合防屈曲支撑及其组装方法，FRP金属组合防屈曲支撑包括：金属芯材，金属芯材的横截面为双轴对称结构；用于约束金属芯材的约束体，约束体为FRP拉挤型材，FRP拉挤型材内部通长形成有与金属芯材横截面形状相匹配的约束腔体；金属套筒，金属套筒套设于FRP拉挤型材外，且金属套筒的内壁贴设于FRP拉挤型材外壁，金属套筒的两端固定有用于限制FRP拉挤型材移动的限位件。本发明可以在保障屈曲约束作用的条件下，极大程度地减轻自重，避免了混凝土浇筑养护的时间消耗，且在FRP拉挤型材外套金属套筒的组合形式便于构件防火保护，有助于工程项目应用，达到消能减震效果。
