Abstract:
Paper's intent is to verify the validity of a method developed in compliance with the concept of the "compressive-force path" for the design of reinforced concrete beams. The method is briefly presented and used to design a number of beams whose behavior is subsequently investigated by experiment. The beams chosen were such that the design details specified by the proposed method were significantly different than those specified by current code provisions. In fact, on the basis of current design concepts, the beams are deemed incapable of sustaining the design load; yet the beams not only sustained safely the specified design load but did so with an amount of transverse reinforcement 70 percent less, in some cases, than specified by current methods.
