Abstract:
The authors classify as strengthened that concrete The authors classify as strengthened that concrete which has less than specified minimum reinforcement thus which has less than specified minimum reinforcement thus distinguishing it from plain concrete and reinforced distinguishing it from plain concrete and reinforced concrete. An approach to design is described for ground concrete. An approach to design is described for ground supported elements which introduces a straight-line transi- supported elements which introduces a straight-line transi-ion between the stress, as a function of moment capacity, tion between the stress, as a function of moment capacity, developed by the plain concrete and that produced by developed by the plain concrete and that produced by the minimum reinforcement using working stress deisgn. the minimum reinforcement using working stress deisgn.
