ÖZETTürkiye'deki yapı stoğunun çok önemli bir bölümünün depreme karşı dayanıksız olduğu ve güçlendirilmesi gerektiği bilinmektedir. Yerinde dökülen ve yapıların çerçeve sistemlerine epoksili ankraj çubuklarıyla bağlanan betonarme (BA) dolgu duvarların yapının deprem davranışını önemli ölçüde iyileştirdiği bilinmektedir. Fakat bu yöntemin binanın boşaltılmasını ve uzun bir süre şantiyeye dönüştürmesini gerektirmesi, araştırmacıları hane sakinlerini sokağa dökmeden olabildiğince ekonomik ve aynı zamanda yapısal olarak etkili güçlendirme yöntemleri geliştirmeye yöneltmiştir. Bu çalışmada önerilen güçlendirme yönteminin prensibi yapıda var olan sıvanmış tuğla dolgu duvarların bazılarının, üzerine yapıştırılan şerit beton panellerle güçlendirilerek birer BA dolgu duvara dönüştürülmesidir. Bu amaçla, mevcut çalışma kapsamında ½ ölçeğe sahip toplam yedi adet sıvanmış tuğla duvar elemanı tersinir tekrarlanır yatay yükler altında test edilmişlerdir. Altı adet deney elemanı şerit beton/betonarme (BA) paneller yapıştırılarak güçlendirilmiştir. Deney sonuçları, beton panel yapıştırma uygulamasının deney elemanlarının yatay yük taşıma kapasitelerini artırdığını ve davranışlarını iyileştirdiğini göstermiştir.Anahtar kelimeler: BA dolgu duvar, güçlendirme, sıvanmış tuğla dolgu duvar, şerit beton/BA panel, tersinir tekrarlanır yatay yük STRENGTHENING OF PLASTERED HOLLOW BRICK INFILL WALLS USING STRIP CONCRETE/REINFORCED CONCRETE PANELS ABSTRACTIn Turkey, majority of the building stock is known to be inadequate against earthquake and is required to be strengthened. Cast-in-place reinforced concrete (RC) infill walls, connected to the frame systems by use of epoxy glued anchorages, improve the behavior of the building significantly. However, requirements of this technique such as evacuation of the building and converts it to a construction area for a long time have directed the researchers developing occupant friendly, economic and structurally effective strengthening techniques. The principle of the technique presented in this paper is based on bonding strip concrete panels on some of the plastered hollow brick infill walls available in the building such that they will behave as RC infill walls. For this purpose, seven plastered hollow brick infill wall specimens with a scale of ½ were tested under reversed cyclic lateral loading. Six wall specimens were strengthened with strip concrete/reinforced concrete (RC) panels. Test results showed that application of concrete panels increased lateral strength of the test specimens and improved their behavior.
An innovative occupant friendly retrofitting technique has been developed for reinforced concrete (RC) building structures with hollow brick infill walls used as partition walls which constitute the major portion of the existing building stock in Turkey. The idea is to convert the existing hollow brick infill wall into a load carrying system acting as a cast-in-place RC wall by reinforcing it with relatively thin concrete plates bonded to the mortar coated infill wall by use of tile adhesive and fixed by 6 (6 mm diameter) bolts. Test parameters were the shape and thickness of the plates, presence of reinforcement in plates, number and arrangement of 6 bolts. It was observed that lateral strength, stiffness, energy dissipation capacity, and ductility of the strengthened infill walls were improved and behaviour was enhanced by the proposed technique. Plates with two different basic shapes were used to strengthen the test specimens.
