Abstract:Analytical studies for the biaxial behavior of RC columns with square cross section subjected to earthquake ground motion are presented. The objective of this study is to estimate the effect of biaxial bending on RC columns. This study extends an existing 2D lattice model to three dimensions. The 3D lattice model can offer reasonable prediction of the shear-carrying capacity of RC members. By comparing analytical results with the experimental results of shaking table tests on two RC columns, it has been confirmed that the 3D lattice-model analysis can reasonably predict the biaxial behavior of RC columns subjected to the bilateral ground motion. In addition, it is found that analysis considering the buckling of reinforcement can accurately predict the seismic response and energy dissipation capacity of RC columns.
