Abstract

This paper presents the seism analysis of a tall building structure (33 m) made of reinforced concrete frames performed according to Romanian Design Code P100–1/2019. This design code allows the seism analysis of a building to be done with the method of equivalent static forces and with the modal method with response spectra. The purpose of this study is to determine the differences between the results obtained with these two methods in order to highlight which results are more trustful. We have chosen to use Finite Elements Method program ETABS, which allows the two analyzes to be performed by specifying the coefficient of the base shear force for static analysis and the response spectrum for modal analysis. In order to highlight the differences between the results obtained with these two methods, the values ​​of the efforts on beams and columns were compared. The analysis of the comparisons made showed that the values ​​of the efforts obtained in the static seism analysis, in the case of this building, are on average 10% higher than those obtained in the modal analysis with response spectra. This certifies that static analysis offers results which cover the results obtained with modal seism analysis.
