Abstract:
A method is presented for the design of nonprismatic concrete columns using the degree of fixity method. The method obviates the need to use effective length factors and to compute of the critical buckling load of the columns. The rotational and translational restraints at the ends of the column can be taken into account, and material nonlinearities are considered using the EI equations given in the ACI Building Code.
