AN ANALYTICAL MODEL FOR STEEL SHEAR WALL S TRENGTHENED WITH CF RP USING COMPOSITE THEORY

In this paper steel plate shear wall strengthen ضy carضon 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 elas tic displacement related to polymer’s fiber usin g 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. Op timum fiber orientation angle for composite sh ear wall was in diagonal tension field. Finite element values via presented model was compared with and co ncluded that the offered model can predict composite shear wall in close range.
