"Early theories on reinforced concrete beams and slabs shear analysis and design"

The various calculation methods of shear behaviour of beams and slabs, available from the scientific literature around the turn of the century are compared in this paper to investigate whether and to what degree these verification and/or design methods are still reliable. A purpose of the paper is also to verify whether there is any historical continuity between the hypotheses lying behind the early theoretical formulations and our understanding of today. The endpoint of this research is thus to provide an operator planning rehabilitation or restoration work with more efficient tools to facilitate a better philological interpretation of the structural behaviour of historical reinforced concrete structures.
