FRP stirrup constraint UHPC-steel pipe combination column component and manufacturing method thereof
The invention belongs to the technical field of building structures, and relates to an FRP stirrup constraint UHPC-steel pipe combination column component and a manufacturing method thereof. The component comprises the UHPC layer, the UHPC layer is arranged on the outer side, connection of beam-column joints is more convenient, and due to the ultra-high performance of UHPC, the component is light, high in strength, high in ductility, high in anti-seismic property, good in crack control capacity and the like. A steel pipe is arranged in the UHPC layer, and the steel pipe endows the combined component with light weight, high strength and good anti-seismic ductility. The FRP stirrup cage is embedded in the UHPC layer, the FRP stirrup cage is used for replacing an FRP pipe, the problem of poor high temperature of the FRP pipe is avoided, and the post-peak ductility of the combined component is improved. Due to the high bonding performance of the FRP stirrup and the UHPC, the cooperative work performance of the FRP stirrup and the UHPC can be improved. The three components have a synergistic effect, so that the combined component has better ductility, toughness, high crack resistance and durability, the steel content is reduced, and the problem of poor high-temperature service of the FRP pipe is avoided.
本发明属于建筑结构技术领域，涉及一种FRP箍筋约束UHPC‑钢管组合柱构件及其制作方法。该构件包括UHPC层，UHPC层置于外侧更便于梁柱节点连接，UHPC的超高性能赋予了构件轻质高强、高延性、高抗震性能及良好的裂缝控制能力等。UHPC层内置有钢管，钢管赋予了组合构件轻质高强及较好的抗震延性。UHPC层内埋置有FRP箍筋笼，以FRP箍筋笼取代FRP管避免了FRP管较差的高温问题，提升了组合构件的峰值后延性。FRP箍筋与UHPC的高粘结性能可提高FRP箍筋与UHPC的协同工作性能。三者协同作用，使组合构件具有较好的延性、韧性、高阻裂性和耐久性，降低了含钢率，避免了FRP管较差的高温服役问题。
