Abstract

Most of the reinforced concrete framed buildings commonly used in developing countries are not secure against earthquakes. Studies on seismic performance of reinforced concrete framed structures showed that; lateral stiffness often needs to be improved. In this study, in order to rehabilitate the structures, performances of ferrocement panels can be used to strengthen the existing hollow brick infill walls such that they act as cast-in-place concrete in fills improving the lateral stiffness is researched. Ferrocement panels are not only to be as light as can be carried by two people easily, but also from the low cost and usefulness against tensional and loads point of view. Previous researches results indicated that strength, stiffness, energy dissipation and story drift characteristics of the reinforced concrete framed building structures can be rehabilitated by the eco-friendly, cost effective and practically applicable seismic retrofitting technique that does not need evacuation of the building with these high-performance ferrocement panels.

6 Şubat 2023 Türkiye Depreminde Hasar Görmüş Betonarme Yapıların Güçlendirilmesi için Alternatif Ferrocement Paneller

Abstract

Gelişmekte olan ülkelerde yaygın olarak kullanılan betonarme çerçeveli binaların çoğu depreme karşı güvenli değildir. Betonarme çerçeveli yapıların sismik performansları üzerine yapılan çalışmalar göstermiştir ki; yanal sertlik çoğu zaman yetersizdir. Bu çalışmada, yapıların rehabilite edilmesi amacıyla, mevcut boşluklu tuğla dolgu duvarların güçlendirilmesinde kullanılabilecek ferrocement panellerin yerinde dökme beton dolgu görevi görerek yanal rijitliği iyileştirme performansları incelenmiştir. Hafif agregalı ferrocement paneller, iki kişinin rahatlıkla taşıyabileceği kadar hafif olması, çekmeye karşı dayanıklı, hafif, düşük maliyetli ve kullanışlı olması nedeniyle tercih edilmektedirler. Önceki araştırma sonuçları, betonarme çerçeveli bina yapılarının dayanım, rijitlik, enerji yayılımı ve kat ötelenmesi özelliklerinin, bu yüksek performansla binanın boşaltılmasına ihtiyaç duyulmadan, çevre dostu, düşük maliyetli ve pratik olarak uygulanabilir sismik güçlendirme tekniği ile iyileştirilebileceğini göstermiştir.
