| Summary: | The estimation of the initial stiffness of columns subjected to seismic
loadings has long been a matter of considerable uncertainty. This paper reports a study
that is devoted to addressing this uncertainty by developing a rational method to
determine the initial stiffness of RC columns when subjected to seismic loads. A
comprehensive parametric study based on a proposed method is initially carried out to
investigate the influences of several critical parameters. A simple equation is then
proposed to estimate the initial stiffness of RC columns. The applicability and
accuracy of the proposed method and equation are then verified with the experimental
data obtained from literature studies. |
