Some procedures that model seismic phenomena consider them as events of a dynamic nature, but there are others that estimate a static nature. At the same time, the non-linear behaviour of the structures can be considered or not in them. It cannot be pointed out that one procedure is completely superior to the others. However, the convenience of integrating them in practice can be argued. In this investigation, taking into account the previous arguments, several procedures are used, namely, the Equivalent Static Method, the Response Spectrum Method and the Time Record Method. The aim is validating the structural analysis in the critical elements of the U-142-143 building, built with the prefabricated Great Soviet Panel system in the city of Santiago de Cuba. After obtaining the calculation requirements, the critical elements turned out to be the transverse exterior panels. In these elements, the shear, axial and maximum moments reach higher values for the Time Record Method; even exceeding the absolute maximum values obtained with the application of the Equivalent Static Method. The combinations of loads that consider predominant seismic actions in the direction of the panels or orthogonal to them, combined with maximum or minimum gravitational loads, are determining factors in the analysis. However, the load combination for which the vertical seismic component predominates is not dominant in the analysis. Likewise, a structural behaviour associated with buildings with irregularities in plan is corroborated.
