Abstract:

In Turkey, where the earthquake is important, the building elements are strengthened by fiber polymer (LP) material that causes a significant increase in the capacity of cargo transportation and system coating in terms of the necessary and sufficient performance under horizontal loads. In this study, the nonlinear analysis of concrete curves, reinforced by LP using the nonlinear final element method, was carried out. Based on experimental studies conducted in the past, final elements models have been created in the ANSYS program. The mechanical properties of the CFRP material used in experimental studies in literature as a system have been tested in laboratory conditions in accordance with ASTM D7522 standards. The material characteristics of the CFRP system obtained from the test results were taken into account in the final elements models and the concrete curves were analyzed under static loads. The final element models are differentiated depending on the CFRP width, the carbon fiber layer and the height of curvature on the curvature side surfaces, and the effects on the curvature performance of the CFRP system have been studied. The width of the applied CFRP system in the curve base and the increase in the number of carbon fiber layers in the CFRP system are seen to increase the cargo transport capacity of concrete curves. If the front side surfaces are also covered with CFRP, a significant increase in the cargo transport capacity has been observed according to the reference surfaces where only the lower surface of the curve is strengthened.
