000009901 520__ $$2eng$$aIn the diagonal-strut macromodel for infilled frames, the axial stiffness of the equivalent diagonal strut is usually calculated by semi-empirical formulas and application diagrams resulted from experimental results in typical one-bay infilled frames. Formulas and application diagrams proposed by Stafford Smith are among the first applied and most widely used. In these formulas and diagrams, the effects of several main modelling parameters on the system’s behaviour, such as the relative beam to column stiffness and the friction coefficient at the frame-infill interface, have not been taken into consideration. In the present work a formation of application diagrams for calculating the effective width of the equivalent diagonal strut is attempted, taking into consideration all the above mentioned factors. To this purpose, the results of an extensive parametric investigation with finite element micromodels were used for the determination of the diagonal strut’s axial stiffness, instead of using experimental results on which most of existing application formulas and diagrams are based.
