Before revision: As a result, structures that were code compliant based on design using the Allowable Stress Design methods may not have been code compliant if reviewed with the LRFD requirements - particularly where the Load and Resistance Factor Design (LRFD) procedures explicitly defined additional analysis which was not explicitly defined in the Allowable Stress Design procedures.
