This graduation thesis deals with the static analysis and design of five story office building with focus
on sesmic resistance. The main structure consist of four moment resisting frames with 10 m span
between the columns, with overall lenght and width of 30,0 m and height of 18,8 m. The longitudinal
stiffes is provided through moment resisting frames in one direction and concentric bracings in the
other direction. Floors are designed as composite slabs that are supported by secondary beams which
are connected to primary beams and columns of moment frames.
The second order analysis with initial global imperfections was performed to determine internal fores
in the structural elements. Analysis were made using SCIA Engineer software. All loads were
determined according to Slovenian standard SIST EN 1991.
Seismic analysis was made using simplified horizontal forces method. The structure is designed
according to rules for high ductility class.
