Flexural Ductility of High-Strength Concrete Members

2019-1-5  Ductility is an important parameter in the RC beams for proper redistribution of moments. In seismic areas, ductility is an important factor in the design of HSC members under flexure. HSC due to its very high compressive strength is less ductile and as such creates a less ductility response in the structural members.
