Szukana fraza: [Abstract = "These dynamic impedances are shown in the displacement vector of a three\-degrees\-of\-freedom frame, which was calculated on the basis of lateral forces distributed over the structure height using the equivalent static method. In this regard, two different calculation norms were chosen\; RPA2003 and UBC97. Finally, a parametric study was carried out, based on the effects of soil densification and the foundation geometry on the response of the RC frame."]
