Simplified Procedure to Calculate by Hand the Natural Periods of Semirigid Steel Frames
Current seismic design codes provide empirical equations for the calculation of the fundamental period of a framed structure primarily as a function of height, and do not consider the effect of beam-column joint stiffness. In the literature, far too little attention has been paid to incorporate this effect in approximate formulas to calculate by hand the natural periods of semirigid steel frames, which is the aim of this paper. The proposed formulas have been developed after modifications of existing formulas in the literature for rigid-jointed plane steel frames. Then, the accuracy of these approximate formulas was verified by a finite element analysis using ABAQUS software. Finally, a parametric study was conducted to highlight the effect of semirigid connections on the natural periods of vibration of plane steel frames.
