Buckling capacity of compression members may change due to inadvertent changes in themember section dimensions or material properties. This may be the result of repair, modification ofcapacity of compression members may be achieved through splicing of plates or utilization of compositematerials. It is very important for a designer to predict the buckling resistance of the compression memberand the important parameters that afect its buckling strength once changes in section and/or materiala compression member whose geometric and/or material properties has been altered resulting in a multi-step non-uniform section. This analytical solution accommodates the changes and modifications to thematerial and/or section properties of the compression member due to the factors mentioned. The analyticalas the repair stage of compression members. Three case studies are presented to show that the proposedanalytical solution is an efficient method for predicting the buckling strength of compression members thattheir section and/or material properties have been altered due to splicing, coping, notching, ducting andcorrosion.
