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 RSM vs 2.6 in TM.

Celem pracy jest prezentacja nowego podejścia do projektowania przekrojów teowych w elementach belkowych, zwanego Metodą Podprzekrojów Prostokątnych (RSM). Jego główną zaletą jest brak konieczności dodawania sił wewnętrznych z komponentów w celu otrzymania sił wypadkowych. W przypadku momentów dodatnich wyniki RSM i Metody Tradycyjnej (TM) okazały się zbieżne. Przy zginaniu ujemnym RSM była bardziej konserwatywna - stosunek powierzchni zbrojenia zaprojektowanego do badanego wynosił 3,3 w RSM vs 2,6 w TM.
