Parametric Assessment of Stiff Column Behavior under Lateral Load

摘要

A parametric study that employed the finite element method was performed with the purpose of examining the lateral load response of stiff column-supported footing systems. The influence of different geometry-based variables in their lateral response was examined. The results of the parametric study, presented in the form of the average of the absolute values of the percent changes, showed that the thickness of the load transfer platform, a granular mattress placed above the soil-column composite, was the geometry-based variable with the greatest influence in the lateral response of the stiff column-supported footing systems examined with an average of 47.25%. The geometry-based variable with the least influence was the stiff column spacing with an average of 3.36%.
