COMPARISON BETWEEN THE LOAD-DISPLACEMENT CALCULATION MODEL BASED ON THE STEEL REINFORCED CONCRETE TENSION COLUMN WITH PRESTRESSED CFRP REINFORCEMENT

Abstract

Abstract: In order to explore the influence factors of load displacement curve and ductility of prestressed carbon fiber reinforced steel reinforced concrete eccentric columns and accurately simulate the change trend of load displacement curve, seven prestressed carbon fiber reinforced steel reinforced concrete columns with different load eccentricity and tension level were tested in eccentric tension, and the load displacement of prestressed carbon fiber reinforced steel reinforced concrete eccentric columns was established on the basis of the test. The model is calculated and the calculated results are compared with the test results. The results show that the load eccentricity and the prestressed tension level are the important factors affecting the load displacement curve and ductility of the specimen, and the calculated value of the load displacement model is in good agreement with the test value, which shows that the model can better reflect the stress and deformation process of the prestressed carbon fiber reinforced steel reinforced concrete eccentric tension column.

Key words: prestressed CFRP reinforcement, steel reinforced concrete column, load calculation model, composites
