Columns

A procedure for carrying out the detailed design of braced columns (ie columns that do not contribute to resistance of horizontal actions) is shown in Table 1. This assumes that the column dimensions have previously been determined during conceptual design of by using quick design methods, for example those presented in the publication 'Economic Concrete Frame Elements'.
