Dolgulu betonarme çerçevelerin sismik yükler altında tepkileri, deprem mühendisliğinin ilgi konusu olmuştur. Düzlem içi tepkiyi ideal hale getirmek için basit basınç çubuk modelleri önerilmiş olmasına rağmen, dolgu duvarlarının düzlem içi katkısı ancak düzlem dışı stabilitesi olması durumunda mümkündür. Yanal yer değiştirmelerin göçme durumunu tayin ettiği düzlem içi davranışın aksine, düzlem dışı göçme durumu depreme bağlı atalet kuvvetleri tarafından tetiklenir ve yük kontrollüdür. Bu çalışmada, sıvalı ve sıvasız geleneksel tuğla dolgu duvarlarının düzlem dışı tepkileri araştırılmıştır. Buna ek olarak, bağ telleriyle dolgu duvarın her iki yüzüne çift taraflı olarak tutturulmuş hasır teller vasıtasıyla düzlem dışı davranışı iyileştirmek için yeni bir sistem önerilmiştir. Bu amaçla ODTÜ Yapı Mekaniği Laboratuarı' nda, betonarme çerçeve içerisinde ki dolgu duvara düzlem dışı yönde deprem yüklerini taklit edecek şekilde sabit basınç uygulamak üzere hava yastığı kullanılan bir deney düzeneği kurulmuştur. Yarı ölçekli betonarme çerçeveler imal edilerek yatay delikli tuğlalarla duvar örülmüştür. Malzeme ve duvar parçası deneyleri yapıldıktan sonra, duvarlar düzlem dışı doğrultuda göçene kadar hava yastığı ile itilmiştir. Artırılan düzlem dışı deplasmana karşılık duvarın yer değiştirme profili, çatlakların yayılımı ve düzlem dışı doğrultuda duvarın kapasitesi kayıt altına alınmıştır. İki taraflı hasır tel takviyesi düzlem dışı kapasiteyi %80 oranında arttırmış, göçmenin oldukça ani ve gevrek olduğu geleneksel duvar davranışını sünek bir hale getirmiştir.

Seismic upgrading of reinforced concrete frames with structural steel elements
Özçelik, Ramazan; Binici, Barış; Department of Civil Engineering (2011)
This thesis examines the seismic internal retrofitting of existing deficient reinforced concrete (RC) structures by using structural steel members. Both experimental and numerical studies were performed. The strengthening methods utilized with the scope of this work are chevron braces, internal steel frames (ISFs), X-braces and column with shear plate. For this purpose, thirteen strengthened and two as built reference one bay one story portal frame specimens having 1/3 scales were tested under constant grav...
Strengthening of brick infilled rc frames with cfrp reinforcement-general principles
Akın, Emre; Özcebe, Güney; Department of Civil Engineering (2011)
There is an excessive demand for the rehabilitation of frame type reinforced concrete (RC) buildings which do not satisfy current earthquake code provisions. Therefore, it is imperative to develop user-friendly seismic strengthening methodologies which do not necessitate the evacuation of building during rehabilitation period. In this study, it was aimed to strengthen the brick infill walls by means of diagonal Carbon Fiber-Reinforced Polymer (CFRP) fabrics and to integrate them with the existing structural...
Explicit nonlinear analysis for quasi-static behavior of frame structures with pid control and mass scaling
Kocamaz, Korhan; Tuncay, Kağan; Department of Civil Engineering (2018)
Performance-based seismic design of reinforced concrete frame systems requires time history analysis of the structural model under earthquake loads and estimation of damage in the members. Time history analysis of these structures is usually performed using implicit time integration methods. For the implicit integration methods, divergence of the solution is typically treated as the onset of collapse of modelled system. In this study, a nonlinear analysis platform that enables the analysis of the effect of ...
Influence of the shear wall area to floor area ratio on the seismic performance of existing reinforced concrete buildings
Günel, Ahmet Orhun; Burak Bakır, Burcu; Department of Civil Engineering (2013)
An analytical study is performed to evaluate the influence of shear wall area to floor area ratio on the behavior of existing mid-rise reinforced concrete buildings under earthquake loading. The seismic performance of five existing school buildings with shear wall ratios between 0.00% and 2.50% in both longitudinal and transverse directions and their strengthened counterparts are evaluated. Based on the structural properties of the existing buildings, additional buildings with varying shear wall ratios are ...
Relationships between felt intensity and instrumental ground motion parameters for Turkey
Bilal, Mustafa; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2013)
Earthquakes are among natural disasters with significant damage potential; however it is possible to reduce the losses by taking several remedies. Reduction of seismic losses starts with identifying and estimating the expected damage to some accuracy. Since both the design styles and the construction defects exhibit mostly local properties all over the world, damage estimations should be performed at regional levels. Another important issue in disaster mitigation is to determine a robust measure of ground m...
