In a traditional seismic analysis, it is mainly considered the existence of seismic forces that work unidirectionally in two or three independent directions. However, it has been demonstrated that the nature of the seismic movement is erratic, that is to say, that the seismic actions act in different directions towards the structure. In the present study, the responses of 4 structural models with a staggered architectural geometry were analyzed using a Spectral Modal Analysis (SMA) and a Linear Time History Analysis (ALTH), with incidence angles increased every 10°, so as to evidence the effects of the seismic bidirectionality against the unidirectional one through the maximum responses of the models. For the ALTH, 3 seismic records were considered, which occurred in Lima-Peru in a type of rigid soil obtained through the Peruvian national accelerographic network CISMID. The results achieved show that, for the Spectral Modal Analysis (SMA), the incidence angle where the greatest responses are presented is 45° for the 4 models, and for the ALTH the incidence angles are variable. Moreover, in both dynamic analyses, evaluating the seismic bidirectionality, responses are obtained from 10 to 40% more than a unidirectional analysis.
