The aim of this study is to find a simple, fast, and economical method for designing
RC cantilever beams instead of the traditional methods. Generally, the concrete beams have been
designed as T-sections so that their flange has failed within the compression zone, which has
embedded with reinforced concrete slab. The structural engineer can select the appropriate
section for each span length, but the trial and error method may be used with more effort and time.
The economic selection has been become more difficult for cantilever beams especially with a
large span due to the significant deflections they have been exposed to. In order to solve this
problem, a current theoretical study has been conducted on a number of locally common dropped
and inverted T-sections for cantilever RC beams that reinforced with a different reinforcement
ratios and their sustained and immediate deflections have been checked according to the ACI -19
provisions. By creating an algorithm and using the Python 3.4 software, the allowable sections
have been identified for each required span length. Three curves have been drawn to choose the
optimum dimensions for both dropped and inverted T-sections easily. In addition, by comparison,
it has been found out that the selection of inverted T-sections has more economy to provide longer
spans than dropped sections
