Abstract (english)

The buildings with a soft storey represent a great danger for the safety of the tenants in seismically
active areas. Because of the improper distribution of stiffness in height of the building, the seismic
effect results in a failure in the most unfavourable way, that is, an unannounced collapse through
a soft storey, whereby plastic joints are formed first in the columns, without dissipation of energy
through plastic joints in the beams. The purpose of this research is to compare the behaviour of a
regular RC building and a RC building with a soft storey, which will show the negative effects that
the soft storey has on the overall behaviour of the building. Additionally, a linear and nonlinear
static analysis of RC buildings with a soft storey is made according to the applicable Macedonian
regulations and according to the Eurocode. The comparison made justifies the applicability of
the recommendations and criteria for the design and construction of these systems. Linear
static analysis of regular RC building and RC building with a soft storey according to Macedonian
regulations and according to Eurocode was performed and a comparison of the obtained results is
given. More detailed insight in the influence of the soft storey to the buildings is given through the
non-linear static analysis (Pushover) made on the same RC building designed according to different
rulebooks, one according to Eurocode and another according to the Macedonian regulations, and
another comparison of the obtained results with a more detailed non-linear analysis was made
where the development of the plastic hinges along the height of the building is shown
