Abstract:
An experimental study was performed on full-scale beam specimens to study the "top bar" effect on the responses. The behavior of beams containing top-cast bars is compared with companion beams containing bottom-cast bars. A top bar factor for these tests is derived and the results are compared with current ACI predictions and with the suggested provisions made by ACI Committee 408. In addition, the influence of transverse reinforcement is investigated.
