Evaluation of Dynamic Collapse of Cantilever Column Under Axial Compression and Lateral Dynamic

The objective of this paper is to construct a method of evaluating the dynamic collapse of a cantilever column under the axial compression and the lateral disturbing force simultaneously. First, a parametric study is carried out to investigate the dynamic collapse behavior of the column idealized by the flexural multi-degree spring-mass system, under the axial compression and the harmonic disturbing force. Secondly, through the results, a method of evaluating the dynamic collapse of the column is proposed by developing the method for this type of SDOF systems. Finally, the dynamic collapse of a uniform column and a stepped one is evaluated by the proposed method.
