First, equivalent single-degree-of-freedom (SDOF) models are investigated, which can account for the effect of gravity or the combined effect of horizontal and vertical excitations. The effect of vertical ground motion on simple RC frame is also studied by considering different geometric configurations including span length, span ratio and story height. The effects of a suite of earthquake ground motion records with different vertical-to-horizontal peak acceleration ratios on the structures are presented and the results are compared with the case of horizontal-only excitation. For equivalent SDOF models, the effect of vertical excitation on horizontal response is mainly examined. 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 ductility and shear capacity of structural members are monitored to assess failure on a local level. The effect of vertical ground motion on axial force, shear demand, and shear capacity is also 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.
