( College of Civil Engineering, Chongqing University, Chongqing 400045, China)Abstract: The secant flexibility-based fiber element with combined flexure and shear was presented. In this model, modified compression field theory was utilized to simulate bi-axial behavior of concrete in each subdivided concrete layered strip. Effectiveness of this method was verified by calibrating the analytical results with those of test.
Keywords: fiber element; reinforced concrete; shear
