Sustainable
building materials are materials that consume minimum energy during their life
cycles and do not harm the environment and human health during the production,
use, maintenance, repair and waste generation of their raw materials. Wood
material is one of the most widely used building materials. However, to ensure
the sustainability of the available resources, the material must be protected
throughout its service life. Wood materials are used in the construction of
buildings for many years. Historical wooden structures in our country need
repair and strengthening over time. Traditional repair methods cause insect
failure, fungus and rot on wood material over time. In addition, the removal of
all damaged elements can cause significant problems, especially in terms of
cost and labor. Therefore, instead of replacing all the wood elements used in
the building, repairing the damaged elements is more suitable for
sustainability. With the regional change, new combinations such as dowels,
nails, bloning techniques are formed. Fiber reinforced polymers provide
significant advantages in terms of visualization while saving time with
reinforcement. Therefore, the use of fiber-reinforced polymers will contribute
to a more sustainable and renewable structure.

Ahşap Malzemelerin FRP ile Güçlendirilmesinin Sürdürülebilirlik Açısından Değerlendirilmesi

Öz

Sürdürülebilir
yapı malzemeleri, yaşam döngüleri boyunca minimum düzeyde enerji harcayan,
hammaddelerinin elde edilmesi, işlenmesi, kullanımı, bakım-onarımı ve atık
oluşumları sırasında çevreye ve insan sağlığına zarar vermeyen malzemelerdir. Ahşap
malzeme en yaygın kullanılan yapı malzemeleri arasındadır. Ancak mevcut kaynakların
sürdürülebilirliğinin sağlanması için malzemenin servis ömrü boyunca korunması
gerekmektedir. Uzun yıllardır ahşap malzeme yapıların inşasında
kullanılmaktadır. Ülkemizde tarihi ahşap yapılar zaman içerisinde onarım ve
güçlendirmeye ihtiyaç duymaktadır. Geleneksel onarım yöntemleri, ahşap
malzemeye zamanla böcek arız olmasına, mantarlaşmaya ve çürüklüğe sebep
olmaktadır. Ayrıca bütün zarar görmüş elemanların sökülmesi özellikle maliyet
ve işçilik açısından önemli problemler ortaya çıkarabilmektedir. Bu nedenle,
yapıda kullanılan ahşap elemanların tamamının değiştirilmesi yerine zarar
görmüş elemanların onarılması sürdürülebilirlik açısından daha uygundur.
Yapılan bölgesel değişiklik ile birlikte kavela, çivi, blonlama tekniği gibi
yeni birleşimler oluşmaktadır. Fiber takviyeli polimerler ile güçlendirme ile
zamandan tasarruf sağlanmakla birlikte görsellik açısından da önemli avantajlar
sunmaktadır. Bu nedenle fiber takviyeli polimerlerin kullanımı daha
sürdürülebilir ve yenilenebilir bir yapı oluşturmaya katkı sağlayacaktır.
