A boundary element solution for the static and dynamic analysis of composite shear walls is developed. The composite shear wall consists of a matrix material surrounding a finite number of inclusions (in-fill walls) with different elastic constants firmly bonded to it. The problem is formulated in terms of the displacement components and all kinds of boundary conditions are encountered. Several numerical examples are worked out to demonstrate and attest the efficiency of the method. The results, whenever possible, are compared with those obtained from analytical or other numerical solutions. The case of homogeneous shear wall with or without holes is included as a special case.
