Test data are presented which demonstrate the applicability to nonrectangular structural concrete members of fundamental plasticity concepts deduced from tests of rectangular structural concrete members. Flexural tests are reported of symmetrical beams with triangular-shaped concrete compression zones, and of unsymmetric T-beams. The behavior of the beams tested, and in particular their ultimate strength, is compared with the behavior and ultimate strength predicted by two theories derived from previous tests of rectangular members. One of the two theories considered is of a general nature and is intended primarily for research purposes the other is based on an equivalent rectangular stress distribution and is suitable for practical design.
