A finite‐element procedure for predicting the frequency of axial‐flexural coupling vibration of frameworks is presented. In addition to the rectilinear beams, the formulation and the procedure are also shown to be highly accurate in the analysis of axial‐flexural coupling vibration of a portal frame by comparing the results with an analytical solution presented herein. Additional examples include a two‐bay portal frame and the single‐bay multi‐story frames. It is found that in the case where the horizontal beam contains floor masses or the frame is composed of multiple stories, substantial discrepancies exist between the axial‐flexural frequencies and the flexural frequencies. In those cases, the axial motion is no longer negligible in the vibrational analysis.
