This paper describes structural performance and a design method of shear walls with an opening that are strengthened by carbon fiber reinforced plastic laminates and adhesive against an earthquake load. A loading test shows that shear strength of shear walls with an opening can be improved by bonding CFRP laminate to wall. The experimental results of relationships between shear force and displacement are simulated by three-dimensional FEM analysis. An equation for calculating the shear strength is proposed using a macroscopic model based on the concept of the arch and the truss mechanism taking account of strengthening effect. The numerical experiments using the 3D model to approximate the test results were carried for shear walls with various eccentric opening and some kinds of concrete strengths under the same size as the specimen in order to show the behavior of shear walls with eccentric opening. As results, it is found that the proposed design formula of shear strength for shear wall is estimated in safety in spite of opening position.
