Fiber reinforced concrete frame structure
The invention provides a fiber reinforced concrete frame structure, and belongs to the field of concrete members. The fiber reinforced concrete frame structure comprises a plurality of frame units formed by connecting a plurality of reinforcement cages, each frame unit comprises a plurality of concrete beams and concrete columns which are crossed and vertically arranged, and the concrete beams andthe concrete columns are composed of the reinforcement cages and concrete poured in the reinforcement cages; prestressed fiber reinforced composite sheets are fixedly clamped on the surfaces of the concrete beams and the surfaces of the concrete columns through anchorage devices, the clamping anchorage devices are connected with the reinforcement cages, and reinforced fiber reinforced concrete joints are formed at the joints of the concrete beams and the concrete columns; and each reinforcement cage comprises in-column profile steel and in-beam profile steel, the periphery of the in-column profile steel is connected with one piece of in-beam profile steel, the in-column profile steel and the in-beam profile steel form a reinforcement cage structure, and fiber reinforced concrete is pouredinto the reinforcement cage structure. The structure adopts a limiting material to effectively improve the tensile strength and the crack resistance of the concrete in a plastic area, and the deformability and the bearing capacity of the plastic area can be enhanced.
本发明提供了一种纤维增强混凝土框架结构，属于混凝土构件领域，包括由多个钢筋笼连接而成的多个框架单元，每个框架单元均包括多根交叉且垂直排布的混凝土梁、混凝土柱，混凝土梁和混凝土柱由钢筋笼和在钢筋笼内浇筑的混凝土组成；混凝土梁和混凝土柱表面均通过锚具固定夹持有预应力纤维增强复合片材，夹持锚具与钢筋笼连接，混凝土梁和混凝土柱的交接处形成钢筋纤维增强混凝土节点；钢筋笼包括柱内型钢和梁内型钢，柱内型钢的四周分别与一个梁内型钢连接，柱内型钢和梁内型钢构成钢筋笼结构，钢筋笼结构内浇筑纤维增强混凝土。该结构采用限位材质有效改善塑性区混凝土抗拉强度和抗裂能力，增强塑性区的变形能力和承载能力。
