This study intends to analyze, in the construction system that is in ascendancy - the
structural masonry, an element that demands a special attention comparing to other
elements: the reinforced concrete masonry beam. The beams carry vertical loads, with
flexure and shear forces. In the theoretical part, the literature review included national and
international papers and codes. The assessed codes were the national (NBR15961-1/2011
and NBR 6118/2014) and international (ACI530-13, AS3700/2001, S304/2014 and Eurocode
6.1/2001). The experimental study includes testing of ten (10) concrete block masonry
beams, designed to fail due to shear forces. As a conclusion, it can be pointed that concrete
masonry beams failure in a similar behavior to concrete beams, except for some
particularities such as prior joint cracking. Furthermore, the specification at Brazilian and
European standards led to considerably higher results than the experimental results while
the specifications at ACI530-13, AS3700/2001, S304/2014 and NBR6118/2014 yielded
reasonable predicted values when compared to experimental results.
