TL;DR: In this article, it was shown that the influence of shearing deformations in the walls is much less than that of the flexibility of the joints between the walls and connecting beams.
Abstract: The continuous connection method of analysis of coupled shear walls assumes that the discrete system of connections, formed by lintel beams or floor slabs, may be replaced by an equivalent continuous medium. By assuming that all cross-beams have a point of contraflexure at midspan, the behavior of the system may be expressed as a single second-order differential equation, enabling a general closed solution to the problem to be obtained. The writers have extended the technique to include shearing deformations of the walls. By comparing the theoretical values of both stresses and deflections with the results from a series of tests on model walls perforated with one or two bands of openings, it is shown that the influence of the shearing deformations in the walls is much less than that of the flexibility of the joints between the walls and connecting beams.

TL;DR: In this paper, a general computer method for determining the distribution of lateral loads in asymmetric multistory structures is presented, which is based on the stiffness method and consists of three stages of analysis: determination of lateral stiffness matrix for each element, formulation and solution of equilibrium equations; and determination of the resultant forces by simple superposition.
Abstract: A general computer method for determining the distribution of lateral loads in asymmetric multistory structures is presented. The proposed solution is based on the stiffness method. The number of unknowns equals three times the number of stories and is independent of the number of stiffening elements (frames, shear walls, etc.). The structure may be subjected to eccentric vertical and lateral loadings and may include any kind and layout of stiffening elements. The method comprises the following three stages of analysis: determination of lateral stiffness matrix for each element; formulation and solution of equilibrium equations; and determination of the resultant forces by simple superposition. Elastic restraints of foundation, rotational constraints of the stiffening elements in their planes at the floor diaphragms, as well as axial deformations in elements may be considered by including their influences in evaluation of the lateral stiffness matrix of the respective element. Results obtained for an example building are evaluated.

TL;DR: In this paper, the stiffness matrix approach has been used to solve frames with or without shear walls, where it is assumed that between the center line and edge of the shear wall the beam is infinitely rigid.
