The aim of this article is to present the new approach to a design of t-shaped beam elements, called a Rectangle Subsections Method (RSM). Its biggest advantage is that the internal forces from the components do not need to be added to obtain the total forces. In case of sagging, the results for RSM and Traditional Design Method (TM) appeared similar. At hogging, the RSM was more conservative – the ratio of the designed to the tested reinforcement area was 3.3 in RSMvs 2.6 in TM.
