In the recent years, strengthening of ReinforcedConcrete (RC) elements using Carbon FiberReinforced Polymers (CFRP) sheets tends to bemore popular depends on development of civilengineer materials. Due to lightweight with highstrength and corrosion properties, CFRP become analternative strength material in strengtheningreinforced concrete structures.Buildings can be damaged because of'many reasonsnowadays. Damaged buildings and strengtheningbuildings with low standards became one of the fastdeveloping subjects all over the World. Buildingsthat purpose of'use has been changed, old buildingsnot in compliance with earthquake regulation anddamaged buildings need to be strengthened. Carbonfiber, used in one of the strengthening techniquesCarbon Fiber Method, despite being thin and lightas shirt fabric, increases the strength of‘componentelement acting as steel plate when applied withepoxy cement. Additionally, as it is more faster andeasier to apply according to traditionalstrengthening techniques and being very light thatdoes not cause extra load increase and givingtimes more strenght than steel, use of this method inconstruction is increasingfastly.Concrete known as typical brittle material whichis too weak in tension with respect to itscompression strength is mostly used withreinforcements for bending of'structures. It can bedefined as inelastic, nonhomogeneous and nonlinearmaterial. In this study it is aimed to investigatebehavior of reinforced concrete sectionsstrengthened by wrapping with Carbon FiberReinforced Polymers (CFRP), which has hightension strength, to eliminate weakness property ofconcrete in laboratory conditions. For this purpose,the IO pieces of concrete samples of' standardcylindrical specimens have 50 mm diameter and300 mm height were prepared. Ready mixedconcrete was used for preparing the concretespecimens with appropriate amount of cement, water,sand, gravel, stone powder, admixtures. After 28 daycuring period, lets the concrete to gain its desiredstrength, can be accepted as water content in themix not allowed to evaporate from the concrete thestandard cylindrical samples obtainedfor wrappingprocess. Firstly, all surfaces ofthe dried standardspecimens with the help of brush have beencleared of dust and similar substances providingdust-flee surface for the fiber application. Thenrequired amounts of' carbon fiber samples wereprepared with suitable dimensions for jacketing thesamples as confinement. of'I () samples preparedas unconfined, of them wrapped with CFRP assingle layered and the other double-layered withthe help of epoxy. Then the 28 days old specimenstested under monotonic uniaxial compression todetermine the strength-strain relation. Also viahorizontal and vertical transducers assembled tosamples, axial and diametrical values have beenexamined. In order to define the descending portionof the concrete behavior curve several compressiveloading proceeds repeated for each sample. Suchcyclic loading, unloading under high deformationsand reloading, process were evaluated to discuss theCFRP effects on concrete behavior. The resultsobtained in this experimental study shown thatconfining by wrapping with CFRP of concretesections examined under repeated axial load inlaboratory environment and strengthening eflect ofwrappedfiber has been observed.As result of' these study, increase of' wrappingnumber has been determined to increase in strengthalso with increase in ductility which is one of' themost important parameters of'seismic performance.In the case of average values of cylinder concretesamples were examined, samples strenghtened bycarbon fiber were observed to show 25% morestrength. It should be noted that the CFRP has nosignificant eflects on behavior of concrete with highstrength.
