The most common damage observed in the building stock in our country
is due to soft / weak storey (Yakut et al. 2022, ODTÜ 2023). Less rigidity and
less strength occuring as a result of using no infill walls on the ground floors
that are higher than other floors and/or used as a store compared to the
upper floors leads to such damage. The main cause of this damage, which is
often seen in various earthquakes, is not to take into account this aspect in
the design and to fail to perform required reinforcement detailing at the end
sections of the element. Figure 1 shows examples of soft storey/weak storey
damage observed in past earthquakes (Dogangun 2004, Yakut et al. 2022,
Bayraktar et al. 2015, ODTÜ 2011).
