Abstract

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.
