Abstract:
A re-evaluation of F. E. Richart's tests of column footings reported in 1948 shows that the use of present design methods, involving shearing stress at a distance d around the column perimeter, does not lead to a consistant factor of safety with respect to shearing failures. A shearing stress at a distance zero around the column was found to be a better measure of shearing strength. The ultimate value of this stress is given as a functionof concrete strength and the relative intensity of flexural loading combined with the shearing force. On this basis a new design approach is discussed with respect to the shearing strength of column footings.
