Presents an ultimate strength method to analyze coupled shear walls. The collapse mechanism is assumed to have plastic hinges at the points of contact of the connecting beams and the shear wall and at the bottom of the latter. The method is applicable to multistory structures comprising different types of simple and coupled shear walls with or without abrupt changes in cross section. [ABSTRACT FROM AUTHOR]

Presents an iterative method for the analysis of arched frames (or gables) which support shells. These gables differ from ordinary frames in their curved shape and in the way they receive load from the shells. Every continuous gable can be divided into "elementary" frames, having only one joint which is free to move. The method presented, which analyzes the whole frame, makes use of stiffness and carry-over factors, which are easily calculated. The solution is achieved in one operation, in which all moments, as well as all horizontal forces produced at the Joints, are bal-anced. As a result there is no need to set up equations for horizontal displacements. This is important because the degree of freedom for displacement is high with arched frames. Using this method, the real moments and axial forces acting in the continuous gable under various load can be determined, and the eccentricity existing between the shell and gable taken into account.
