The selected 13 RC structures are designed to Korean Building Code 2009 by considering the different geometric configurations. The earthquake ground motions from nine stations are selected and the original records are manipulated with appropriate scale factor to match with seismic hazard in Korea. The effects of a suite of earthquake ground motion records with various vertical-to-horizontal peak acceleration ratios on RC frames are evaluated through nonlinear time history analyses. Analytical results are compared with the case of horizontal-only excitation. The analysis results from RC frames with different geometric configurations are also discussed. The effect of the vertical earthquake component on damage are taken into account. The structural response of RC frames is investigated at both the global and the local levels. Interstory drift is considered as a global failure criterion, while the effect of vertical ground motion on axial force, shear demand, and shear capacity of structural members is investigated. It is observed that the inclusion of the vertical component of ground motion significantly affected the response of RC frames. It is therefore concluded that vertical ground motion needs to be included in analysis for assessment and design.
