Experimental and analytical study of the flexural behavior of basalt fiber‐reinforced concrete beams

Abstract

AbstractIn this work, the theoretical model for predicting the flexural behavior of steel‐reinforced basalt fiber‐reinforced concrete (RBFRC) beams was developed and the results were experimentally validated. The experimental results presented two failure modes of the RBFRC beams including flexural failure and flexural‐shear failure. The load‐carrying capacity, deformation ability, and crack resistance of RBFRC beams failing in flexure can be significantly enhanced with the addition of chopped basalt fiber. To verify the theoretical model, the predicted results were compared with the experimental results of RBFRC beams, and the relative error between the two methods is very small. Based on the theoretical method, a parametric study was conducted to identify the influence of several crucial materials and structural parameters on the flexural behavior of RBFRC beams.
