Calculates shear capacity and confinement reinforcement of circular and oblong shape reinforced concrete columns in compliance with seismic provisions of AASHTO 17th edition and and AASHTO LRFD.

The spreadsheet design is based on interpretation of design methodology. As much as the authors have tried to achieve an accurate product, the codes rely upon interpretation as well as decisions drawn from engineering judgment. There are no guarantees or express warranties implied in the use or output of these programs that assures accuracy other than the efforts of the programmers' intent to achieve perfection.
