Abstract:
Fiber Reinforced Polymer (FRP) tendons are suitable to be used in concrete beams exposed to aggressive environments. This study proceeds the design and it presents the flexural capacity (in relation to the moment-curvature) for composite sections (reinforced with steel bars and pre-stressed FRP) rectangular, T-section which has been bent and broken. The failure is in attending with strain softening, stress hardening of fiber reinforced concrete (FRC) and reinforcing with steel bars and polymer. Using the predicted moment-curvature relationship, a numerical method is used to estimate the load deflection response at sample beams under concentrated and uniform loads. A parametric study will be conducted to evaluate the effects of various parameters that describe the pre-stress level exerted to FRP and steel bars. A simplified analytical approach will be developed for designing of pre-tensioned precast beams. After comparison of the flexural response of beams; we will present the best section and the best pre-stressing surface
