Szukana fraza: [Abstract = "Paper presents the results of dynamic behavior analysis of a high\-rise building under seismic loads as part of the \"base\-foundation\-building\" system. Analysis covers different types of reinforced concrete construction with girder frame and non\-girder frame. Using modal analysis, paper presents differences in mode shapes and frequencies caused by the presence or absence of girders. Paper also demonstrates variations in the stress\-strain state for the vertical bearing structures under the seismic load for different frame types."]
