FRP rebar: Shear reinforcement and detailing
This second column taken from my new book Composites for Construction — Structural Design with FRP Materials (published by John Wiley & Sons Inc., New York, N.Y.) focuses on the design of concrete members that have FRP main tension reinforcing bars and are subjected to transverse shear forces (Chapter 6) and FRP reinforcement detail design (Chapter 7).The flexural concrete members that fall into the scope of this column are slabs and beams.
