Betonarme perde duvarların farklı yapı malzemeleri açısından değerlendirilmesi

Öz

Perde duvarlar yüksel yanal rijitliklerinden dolayı deprem, rüzgâr gibi yatay kuvvetleri karşılamada en çok tercih edilen yapı elemanlarıdır. Gelişen teknoloji ile birlikte hem yapı malzemelerindeki hem de deney düzeneklerindeki gelişmeler ışığında perde duvarların farklı yöntemlerle incelenmesine olanak sağlamıştır. Bu çalışma kapsamında uzun yıllar boyunca betonarme perde duvarlar genel kabul görmüş parametreler yerine yenilikçi malzemeler ve deney koşulları bakımından ele alınmıştır. Betonarme perde duvarlar gerek lifli beton, hafif veya yüksek dayanımlı beton, FRP donatılar gibi malzemeler gerekse de donma-çözülme, korozyon, güçlendirme gibi amaçlarla irdelenmiştir. Yüksek katlı binalarda kullanımı neredeyse zorunlu hale gelen betonarme perde duvarların önümüzdeki yıllar içerisinde geleneksel çelik donatı düzeninin yerine daha yüksek mekanik ve durabilite özelliklerine sahip donatılara, geleneksel betonun yerine geleneksel betonun zayıflıklarının giderileceği özel çimento esaslı kompozitlerle üretileceği aşikârdır. Bununla birlikte tipik beton ve donatılı perde duvarlar yerine kompozit malzemelere kayacağı da beklenilmektedir. Çalışma kapsamında betonarme perde duvarların yapı malzemeleri perspektifinde davranışları ele alınmıştır.

Evaluation of RC shear walls in terms of different construction materials

Öz

Shear walls are the most preferred structural elements to resist the horizontal loads due to high lateral stiffness. With the advancing technology, it has allowed the shear walls to be examined with different methods in the light of developments in both building materials and experimental setups. RC shear walls have been examined in terms of both the materials such as fiber concrete, lightweight concrete, high-strength concrete, fiber-reinforced polymer (FRP) bars, freeze-thaw resistance, corrosion resistance, and strengthening. It is expected that RC shear walls will be produced with reinforcements with higher mechanical and durability characteristics in the coming years, instead of the conventional steel reinforcement arrangement. It is obvious that instead of conventional concrete, it will be produced with special type cement-based composites, where the weaknesses of conventional concrete will be eliminated. The paper presents the behavior of RC shear walls within the constructional materials perspective.
