Seismic Response of Structures with Rocking Columns

Abstract

This dissertation revisits the problem of the rocking behaviour of free-standing columns and their incorporation as integral members of earthquake resistant structures. A number of FE models were developed and analyzed to assess the rocking response of structures subjected to ground motion excitations. Square and variable cross-section blocks have been considered to examine the effect of the geometry of the rocking columns. Using the observed results from SAP2000 and analytical solutions for the free vibration response of rocking columns, the ability of the proposed models to predict the rocking behaviour columns under earthquake excitations and free vibration is evaluated. Results of the analyses have been assessed primarily in terms of maximum and mean displacements, drift, and values of the fundamental period.
