HM-CFRP İLE GÜÇLENDİRİLMİŞ KOMPOZİT I-KİRİŞLERDE HM-CFRP’NİN SIYRILMAMASI İÇİN FAYDALI MESAFENİN BELİRLENMESİ

Elif AĞCAKOCA 1

Fiber Takviyeli Polimer (FRP) malzemelerinin korozyona dayanıklı olması, ince ve hafif olması, sistemin ağırlığını fazla artırmaması, yorulmamın sebep olduğu çatlakları önlemesi gibi nedenlerden dolayı, güçlendirmede tercih edilmektedir. Çeliğin dayanıklı bir malzeme olmasından dolayı, güçlendirilmesinde kullanılacak FRP malzemesinin de yüksek dayanıma sahip olması gerekmektedir. Son yıllarda üretilen Yüksek Modüllü Karbon Takviyeli Polimer (HM-CFRP)’in çelik kirişlerin güçlendirilmesinde iyi bir performans göstereceği düşünülmektedir.

DEFINING DEVELOPMENT LENGTH OF HM-CFRP IN COMPOSITE I-SECTION STRENGTHENED WITH HM-CFRP

Elif AĞCAKOCA 1

Fiber Reinforced Polymer (FRP) materials are preferred in strengthening processes as these materials are resistive against corrosion, thin and light, i.e., they do not cause a significant increase in the weight of the system, and good for preventing the fatigue cracks. As the steel has high strength, FRP material used for strengthening should also have high strength. It is thought that High Modulus Carbon Fiber Reinforced Polymer (HM-CRFP) produced in recent years shows a high performance in strengthening of steel beams. The aim of this study is to address the development length for HM-CFRP fiber material which is used in strengthening of steel members. Development length defines the length of HM-CFRP for which the capacity of the fiber material is not limited with the slip from the steel interface but the rupture of fibers.
