Abstract

Lifli polimer kompozitlerle güçlendirme hızla yaygınlaşan yeni nesil güçlendirme tekniklerindendir. Karbon esaslı lifli polimerler (CFRP) betonarme yapı elemanlarının eğilme ve kesme kapasitelerinin artışının yanı sıra durabilite yönünden de etkili çözümler oluşturmaktadır. Özellikle mimari fonksiyonun korunması gereken yapılarda geleneksel güçlendirme tekniklerine göre daha uygundur. Çalışmanın konusu, DBYBHY2007’ye göre tasarım ve analizleri tamamlanan, Çorlu’da konvansiyonel betonarme yöntemi ile inşaa edilmiş, çift yönlü dişli döşemelerin kullanıldığı çerçeve sistemli mevcut ilaç üretim tesisinin, değişen işletme yükleri altında TBDY2018 esaslarına göre deprem performansının belirlenmesi ve çift yönlü dişli döşemelerin düşey yük kapasitelerinin artışı için CFRP’lerin kullanımının uygunluğunun değerlendirilmesidir. Uygulamada özellikle CFRP’ler ile gerçekleştirilecek güçlendirmenin etkinliği çalışma kapsamında araştırılmıştır. Yapı deprem performansı belirlendikten sonra yapıda artması öngörülen işletme yükleri sebebiyle oluşacak ilave tesirlerin CFRP’lerin kullanıldığı güçlendirme ile gerçekleştirilmesi projelendirilmiş ve sahada uygulanmıştır. İlaç tesisleri mimari fonksiyon özel olarak belirlendiği alanlardır. İlaç tesisi gibi oldukça hijyenik bir ortamda güçlendirme alternatifleri araştırılmış ve yapısal güvenlik karşılaştırması yapılmıştır. Yapının deprem güçlendirme uygulamasında kompozit malzemelerle güçlendirmenin avantajlarından yararlanılmış ve geleneksel yöntemlere göre avantaj ve dezavantajları belirlenmiştir.

Increasing the Vertical Load Capacity of Reinforced Concrete Waffle Slabs With Varying Operating Loads Using CFRP

Abstract

Retrofit with fiber polymer composites is one of the new generations retrofitting techniques that is rapidly becoming widespread. CFRP provide effective solutions in terms of durability as well as increasing the flexural strength and shearing capacities of RC structural elements. It is more suitable than traditional retrofitting techniques, especially in buildings where the architectural function must be preserved. The subject of the study is to determine the earthquake performance according to TBEC2018 principles of the existing medicine production facility with a frame system, which was built with conventional RC method in Çorlu. In practice, the effectiveness of retrofitting with CFRPs was investigated within the scope of the study. After determining the earthquake performance of the building, the realization of the additional effects that will occur due to the operating loads expected to increase on the structure, with the retrofit using CFRPs, was designed and applied on the site. In a highly hygienic environment, retrofitting alternatives have been investigated and structural safety comparison has been made. In the earthquake retrofitting application of the building, the advantages of retrofit with composite materials were utilized and advantages and disadvantages were determined compared to traditional methods.
