Abstract:
Using of CFRP carbon sheets because of their high strength, lightness and ease of use have been very expanded in retrofitting concrete members. Including shear walls systems FRP can be used in order to rebuild or maintain the strength of an aged structural member. Repairing, or retrofitting of the intact structural member is conducted to enhance the structural resistance that was deteriorated due to the overloading, construction ignorance and so on. In this study, a model of coupled reinforced shear walls with changing the shape of CFRP fibers arrangement under lateral loading is considered. Then, the effect of coupled concrete compression shear wall resistance vary is investigated on the retrofitting. In all stages, the comparison among the proposed arrangement shape of CFRP fibers are accomplished in terms of lateral load carrying capacity of the specimens. Accordingly, the best form of fiber formation is recommended. Finally, it was concluded that the most optimistic fiber arrangement is fully covered and the next choice is vertically covered FRP arraignment.
