主 题:basalt Fiber-reinforced polymer bars reinforced concrete beams finite element analysis damaged plasticity model design codes
摘 要:Fiber-reinforced polymer(FRP)bars are widely used as internal reinforcement replacing the conventional steel bars to prevent from *** the different types of FRP bars,basalt FRP(BFRP)bars have been used in different structural applications and,herein,three already tested concrete beams reinforced with BFRP bars are analyzed using three-dimensional(3-D)finite element analysis(FEA).The beams were tested in four-point *** the FEA the behavior of concrete is simulated using the^Concrete-Damaged Plasticity^^model offered in ABAQUS *** research presented here presents a calibrated model for nonlinear FEA of BFRP concrete beams to predict their response considering both the accuracy and the computational *** calibration process showed that the concrete model should be regularized using a mesh-dependent characteristic length and material-dependent post-yield fracture and crushing energies to provide accurate mesh-size independent *** results were compared to the test results with regard to failure load and crack *** the test results and the numerical results were compared to the design predictions of ACI 440.1R-15 and CSA S806-12,where CSA S806-12 seems to overestimate the shear strength for two beams.
