RESUMO

This work presents an experimental investigation about the reinforcement design technics in beam regions with variation located at the height of the cross section. By the obtained results, the structural behavior of the disturbed regions near discontinuities in beams was analyzed, varying the reinforcement quantity and design, with usual strength concrete, and a model with high strength concrete, in order to have comparisons between them. It was verified that the different behavior between executed models is related with the concrete rigidity used and its reinforcement design. Because of the larger rigidity high strength concrete, a better performance was obtained in comparison with the models made of usual strengh concrete. The bended and vertical mixed suspension reinforcement design presents a better performance, as the presence of web reinforcement. However the efficiency reinforcement design depends on the load quantity which must be suspended
