Abstract: In this thesis,some simple analytical FEA(finite element analysis) models are developed and utilized to determine the shear strain and seismic capacity of the frame joints of continued projects strengthened by two different methods,bonding steel and CFRP(carbon fiber reinforced plastic).The shear mechanism,failure mode,deformation capacity,bearing capacity and the reliability of the reinforced models and un-reinforced model are gathered to determine the influence produced by the reinforcements.Results of FEA show that both strengthening methods have significant influences on their failure capacity and seismic capacity.From some mechanical aspects,bonding steel proves more suitable for better engineering performance.
