Inclusion of the vertical seismic acceleration in one-story buildings analysis I. ~ernkndez-~avila', S. cominetti2, F. 01iva2 & 0 . z6iiiga2 '~chool of Civil Engineering at Civil Works, Universidad Central, Santiago, Chile 2~epartment of Civil Engineering, Universidad de Santiago, Chile Abstract The principal parameters that control the elastic behavior of one-story reinforced concrete building models are analyzed in this paper. Models are subjected to seismic ground motions considering the action of the three-recorded ground accelerations, u,, uy and ii,. The horizontal components, ii, and u , are considered acting in a critical angle of incidence determined for each analyzed model. This effect has been thoroughly studied in previous works. The influence of the vertical ground acceleration on the seismic response has not been exhaustively studied. Adequate and simple methods to consider the combined effects of the three ground motion components for seismic design are proposed in this work. Th
