Abstract:

 


In recent earthquakes occurred in Turkey, an
unexpected number of reinforced concrete (RC) minarets were heavily damaged or
collapsed causing loss of lives and economic damages. These structures can be
counted as the most common constructed slender structures in Turkey. Therefore,
the detailed behavior of these slender structures should be determined in order
to strengthen the existing ones and construct safer and stronger RC minarets.
In this study, the most common constructed types of RC minarets were analyzed under
17 August 1999 Mw 7.4 Kocaeli Earthquake for the determination of the
effectiveness of strengthening techniques namely fiber reinforced polymers
(FRP) and buttresses. Also, soil-structure interaction (SSI) is included in the
dynamic seismic analyses of the minarets as proposed by Burman et al. (2012).
At the end of the analyses performed, it was determined that FRP strengthening
is more effective in enhancing the seismic response of RC minarets as the
height of the minaret increases when compared with the buttress strengthening.
Also, the stress demand locations predicted from the dynamic seismic analyses
of the representative minarets were found to be consistent with the damages
observed in recent earthquakes.

Türkiye'de son zamanlarda
meydana gelen depremlerde, beklenmeyen sayıda betonarme minare, can ve ekonomi
kaybına neden olarak ağır hasar görmüş veya tamamen yıkılmıştır. Bu yapılar,
Türkiye'deki en yaygın inşa edilmiş narin yapılar olarak sayılabilir. Bu nedenle,
bu narin yapıların ayrıntılı davranışı, mevcut yapıların güçlendirilmesi ve
daha güvenli ve güçlü betonarme minarelerin inşa edilmesi için belirlenmelidir.
Bu çalışmada, en yaygın inşa edilmiş betonarme minare tipleri, 17 Ağustos 1999
Mw 7.4 Kocaeli Depremi etkisi altında, güçlendirme tekniklerinin,
yani lifli polimerlerin (LP) ve payandaların etkinliğinin tespiti için analiz
edilmiştir. Ayrıca, Burman vd. (2012) tarafından önerilen zemin-yapı
etkileşimi, minarelerin dinamik sismik analizlerine dahil edilmiştir. Yapılan
analizlerin sonunda, LP güçlendirmesinin, yükseklik artışı oldukça payanda
takviyesiyle güçlendirmeye kıyasla betonarme minarelerin sismik davranışında
daha etkili olduğu tespit edilmiştir. Ayrıca, temsili minarelerin dinamik
sismik analizlerinden tahmin edilen gerilme talep bölgelerinin son depremlerde
gözlemlenen hasarlarla tutarlı olduğu tespit edilmiştir.
