Fiber reinforced polymers (FRPs) have gained popularity in upgrade projects for reinforced concrete structural elements within the last decade because of its ease of application and high strength-to-weight ratio. In the design of an effective retrofitting solution by means of an FRP system, the anchorage capacity has an important role. This study presents the results of an experimental program conducted to determine the strength of carbon fiber reinforced polymers (CFRPs) bonded to concrete prisms or hollow clay tiles that are finished with or without plaster. In the experimental program, different types of anchorage methods were tested in a double shear push-out test setup. A simple and effective strength model is proposed for strip type anchorages based on the existing analytical models and experimental observations from this study. This new model is suitable for determining the design capacity of CFRP-to-concrete and CFRP-to- hollow clay tile joints with or without plaster and accounts for the presence of embedment and concrete strength. Obtained results by using this model were found to closely match with the experimental observations.

Bonding efficiency of roller compacted concrete with different bedding mixes
Özcan, Sinan; Yaman, İsmail Özgür; Department of Civil Engineering (2008)
Roller Compacted Concrete (RCC) has rapidly evolved from a concept to a material and a process which is used throughout the world for faster and more economical construction of dams. Currently, there are more than 250 RCC dams, completed or under construction, in the world. On the other hand, currently, there are only two RCC dams completed (Suçatı and Cindere Dams) and two under construction (Beydağ and Çine Dam) in Turkey. RCC dams are constructed in a series of compacted layers usually 30 cm in thickness...
Strength of carbon fiber reinforced polymers bonded to concrete and masonry
Serdar Camli, Umit; Binici, Barış (Elsevier BV, 2007-07-01)
Fiber reinforced polymers (FRPs) have gained popularity in upgrades of reinforced concrete structural elements within the last decade because of their ease of application and high strength-to-weight ratio. In the design of an effective retrofitting solution using FRP systems, the anchorage capacity has an important role. This study presents the results of 57 double shear push-out tests conducted to determine the strength of carbon fiber reinforced polymers (CFRPs) bonded to concrete prisms and hollow clay t...
Fiber reinforced polymer confined rc circularcolumns subjected to axial load and bending moment
Doruk, Koray; Binici, Barış; Department of Civil Engineering (2006)
Fiber reinforced polymers (FRPs) have gained increasing popularity in upgrades of reinforced structural elements due to high strength to weight ratio and ease of application. In this study, the effectiveness of the carbon reinforced polymer wrapping (CFRP) on ductility and strength of circular reinforced concrete columns, made of low strength concrete, is presented. Four circular reinforced columns with similar dimensions, longitudinal and confining steel reinforcement were tested under combined axial load ...
An improved finite grid solution for plates on generalized foundations
Karaşin, Abdulhalim; Gülkan, Polat; Department of Civil Engineering (2004)
In many engineering structures transmission of vertical or horizontal forces to the foundation is a major challenge. As a first approach to model it may be assumed that the foundation behaves elastically. For generalized foundations the model assumes that at the point of contact between plate and foundation there is not only pressure but also moments caused by interaction between the springs. In this study, the exact stiffness, geometric stiffness and consistent mass matrices of the beam element on two-para...
Improving ductility and shear capacity of reinforced concrete columns with carbon fiber reinforced polymer
Özcan, Okan; Özcebe, Güney; Department of Civil Engineering (2009)
The performance of reinforced concrete (RC) columns during recent earthquakes has clearly demonstrated the possible failures associated with inadequate confining reinforcement. The confinement reinforcement requirements of older codes were less stringent than present standards. Many studies were conducted by applying different retrofitting techniques for RC columns that have inadequate confinement reinforcement. A new retrofitting technique by means of Carbon Fiber Reinforced Polymer (CFRP) was developed an...
