AN ANALYTICAL MODEL FOR STEEL SHEAR WALL STRENGTHENED WITH CFRP USING COMPOSITE THEORY

In this paper steel plate shear wall strengthen by Carbon Polymer’s Fiber was studied. An equation has been proposed for elastic strength using composite theory and maximum work failure model, and another equation has been obtained for elastic displacement related to polymer’s fiber using virtual work principle. Considering fibers and shear wall web as a layer and super positioning plate and fiber behavior, composite shear wall model was achieved. Optimum fiber orientation angle for composite shear wall was in diagonal tension field. Finite element values via presented model was compared with and concluded that the offered model can predict composite shear wall in close range.
