| Zusammenfassung |
| Turkey is situated in a very active earthquake region. In the last century,
several earthquakes resulted in thousands of deaths and enormous economic
losses. In 1999, the Kocaeli earthquake had an approximate death toll of
more than 20 000, and in 2011 the Van earthquake killed 604 people. In
general, Turkish residential buildings have reinforced concrete structural
systems. These reinforced concrete structures have several deficiencies,
such as low concrete quality, non-seismic steel detailing and inappropriate
structural systems including several architectural irregularities. In this
study, the general characteristics of Turkish building stock and the
deficiencies observed in structural systems are explained, and illustrative
figures are given with reference to the Turkish Earthquake Code 2007.
The poor concrete quality, lack of lateral or transverse reinforcement in
beam–column joints and column confinement zones, high stirrup spacings,
under-reinforced columns and over-reinforced beams are the primary causes of
failures. Other deficiencies include weak-column–stronger-beam formations,
insufficient seismic joint separations, soft-story or weak-story
irregularities and short columns. Similar construction and design mistakes
are also observed in other countries situated on active earthquake belts.
Existing buildings still have these undesirable characteristics, and so to
prepare for future earthquakes they must be rehabilitated. |
