Material Nonlinearity Effects on Dynamic Second-Order Effects of Slender RC Columns under Seismic Load

Abstract:

This study investigates the influence of material nonlinear in slender reinforced concrete (RC) columns dynamic second-order effects under seismic load. The stiffness reduction coefficient is adopted in this paper. To identify the significance of various effects in terms of the dynamic second-order effects of the slender RC columns, nonlinear dynamic analyses are conducted for different periods and stability coefficients of simulated models with rare occurrence earthquake. On the basis of the obtained numerical results, the influence of material nonlinear for dynamic second-order effects are reviewed.
