Abstract

The applications of FRP-based polymers for improving concrete structures have been significantly growing during the recent years. The main cause for the aforesaid extension deals with the requirement for extending the life of the infrastructure and improving the infrastructure in all parts of the world. High hardness, low weight, corrosion resistance, easy and quick installation, greater flexibility in design, lower total cost (including time, materials and performance) than steel sheets are the important features of FRP. The efficiency of the FRP enclosure function deals with the compressive strength of the concrete feature, the material and thickness of the pin and the angle or direction of the fiber. The axial behavior and bearing capacity of the columns are a function of the stress level of the aggregate conglomeration. The type of fiber, the number of ply layers, the fiber positioning angle and the compressive strength of the concrete are important in the column behavior. The parameters investigated and studied in the present research were investigated the impact of type of fibers including GFRP and CFRP, number of polychromatic layers, pinch angle, concrete compression strength of samples, including 3 resistances of 20, 35, 50 MPa, as well as the adhesion pattern of fibers. Considering the aforesaid cause and objective, 23 samples of unconventional concrete cylinders with a diameter of 200 mm and a height of 600 mm including 10 samples with a zero-degree fiber orientation, 10 samples with different fiber positioning angles and 3 control samples were tested for comparison. Following the rounded specimens’ processing, they were subjected to a pure axial pressure test at a fixed rate of displacement through a hydraulic jack. The measured values in this work included axial stress, axial strain and lateral strain. Based on the results, the number of layers and its type bears a great impact on sample behavior. Based on the results, the amount of resistance, formability and absorbed energy of the samples increase with the polishing of the column. Plus the aforesaid, raising the angle of the fiber position relative to the horizon, results in decrease in the amount of resistance, absorbed energy, and formability.
