concrete frame structure;  Seismic performance research;  Repeated planting at low levels;  Carbon fiber cloth reinforcement

Taking a frame structure of a two-story reinforced concrete industrial plant as the prototype, according to the 1:3 scale model, the reinforced concrete frame specimen was designed, and the sorghum ends, column ends and nodes of the frame were reinforced with carbon fiber cloth, and then the frame was tested with horizontal and low cycle repeated loads. Based on test results. The crack development, seismic resistance and failure characteristics of the reinforced concrete frame specimen reinforced with carbon fiber cloth reinforced in good condition were analyzed, and the hysteresis curve, skeleton curve and hysteresis curve of column end steel bar and CFRP cloth were drawn. The seismic performance of the concrete frame structure reinforced with carbon fiber cloth was studied. The test results show that the concrete frame structure with good carbon fiber cloth reinforcement has good seismic performance and hysteresis energy dissipation capacity.
