Bending moments distribution in support zones of continuous beams

Abstract

Three different methods to round off the bending moment diagram in support zones of continuous beams or frames are shown in this paper. The first method is based in heometrie, obtaining the polinomic equation of the transition curve between bending moment diagrams in both sides of the support. The second and third methods are based in different reaction stress diagrams in the support under the action of the beam. Finally, there is a comparison between the results of the three methods in several examples.
