LRFDShear Computes ultimate capacity of reinforced/prestressed concrete members subjected to combined action of shear, flexure, torsion and axial forces. The calculations performed in accordance with AASHTO LRFD 2006 Edition. The spreadsheet provides analysis results summary for multiple sections and detailed procedures for a single section. US and SI units

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.
