The wave propagation procedure for structural dynamic response analysis had been discussed in depth by
various theories and analytical models, verified by field monitoring records from well-instrumented buildings
under earthquake loads. However, the visualization of this phenomenon upon a numerical model by a practical
civil engineering sense has been less of a concern. This study numerically investigates the efficiency of the
frame element to detect the essential physics of wave propagation phenomenon in tall structures. The explicit
solver is implemented to investigate the propagation of a transverse and a longitudinal pulse-like wave through
frame element member a 300 m tall mega column. The considered column is modeled using a frame element,
and the excitation pulse-like wave is applied at the fixed base. The study indicates that the frame element is
efficient in detecting longitudinal wave propagation accurately; meanwhile, it yields misleading results regarding
the propagation of the transverse shear waves.
