Fiber-reinforced ultrahigh-strength and ultrahigh-toughness reinforced concrete structure and preparation process thereof
The invention belongs to the technical field of reinforced concrete building components, and particularly relates to a fiber-reinforced ultrahigh-strength and ultrahigh-toughness reinforced concrete structure and a preparation process. The reinforced concrete structure comprises a reinforced concrete column, wherein the reinforced concrete column comprises a lower column body and an upper column body; a pair of superposed beams are symmetrically arranged around the center of the central axis of the reinforced concrete column, and each superposed beam comprises a precast beam and a superposed layer post-poured on the precast beam; one end, close to the reinforced concrete column, of the precast beam is sunken inwards to form a key groove, and the section of the key groove is U-shaped; steel strands are arranged in the precast beam, and each steel strand extends out of the corresponding key groove from the inner bottom of the precast beam; the beam-column joint is used for connecting the lower column body, the upper column body and the superposed beam through modified concrete poured on the end face of the top end of the lower column body and in the key groove; one end of the friction damper is fixed on the bottom surface of the precast beam, and the other end of the friction damper is fixed on the side surface of the lower column body.
本发明属于钢筋混凝土建筑构件技术领域，具体涉及一种纤维增强的超高强超韧性钢筋混凝土结构及制备工艺。该钢筋混凝土结构包括钢筋混凝土柱，包括下柱体和上柱体；叠合梁，绕钢筋混凝土柱中轴线中心对称设置一对叠合梁，每一叠合梁均包括预制梁和后浇在预制梁上的叠合层；预制梁靠近钢筋混凝土柱的一端向内凹陷，形成键槽，键槽的截面呈U型；预制梁内设置有钢绞线，每一钢绞线从预制梁内底部延伸至键槽外；梁柱节点，浇筑在下柱体顶端端面上和键槽内的改性混凝土，连接下柱体、上柱体和叠合梁；摩擦阻尼器，设置在预制梁与下柱体连接处的侧面，一端固定在预制梁底面，另一端固定在下柱体侧面。
