Description
This paper analysis the seismic behavior of a multi-story building that has no structural regularity based on the European standards for the design of earthquake-resistant structures. The analyzed structure is an equivalent system with walls, which does not meet the requirements for rigidity against torsion. Structural analysis, modal, and pushover analysis of the building are analyzed using the ETABS software. In this study, the modeling of the walls was carried out as linear but also surface models and the influence of the width of the participating vertical elements on the stiffness to the principal axes. It is presented also dimensioning of the structural elements like columns, beams, and shear walls based on the results obtained from the seismic analysis.
