Abstract
A finite element procedure for the inelastic dynamic analysis of cylindrical structures subjected to lateral dynamic load and axial thrust is given. The plastic strains developed in the structure are treated as fictitious equivalent loads and the neutral axis at each section is determined by using a subsection concept. Equations of motion are then solved numerically by the direction integration method. The finite element procedure is verified by the exact solution using a continuum analysis. Application of the procedure is made to investigate the effects of axial thrust on the inelastic dynamic response of a tall cylindrical structure. The present method may be applied to the analysis of practical designs of cylindrical structures.
