THE INITIAL CRACKING MOMENTS OF THE BRACKETED PARTS OF CONCRETE BEAMS

Abstract

The beams with brackets at the ends, have the tendency to crack from the reentrent corners of the bracketed parts, the strength of this cracking of reinforced and prestressed concrete beams is investigated.
An equation is presented for predicting the initial cracking moments, the calculated results are checked by the results of experiments which are tested under both moving load and two points load. To simplify the design work, design charts are also presented.
