Often the moment-resisting frame of a tall building is supplemented by shear walls running the full height of the building. Under lateral loads, interaction between the shear walls and frames, due to flexural deformations of the walls, leads to complex analytical problems. These are amenable to an approach by successive approximations similar to that of beams on elastic foundations. If the building is fairly symmetrical, a good First approximation can be obtained from the solution of a differential equation which is based on the assumption of complete uniformity. The solution to the differential equation is given as a set of graphs. The authors apply the method to one particular. A numerical method is set up to systematize successive cycles of iteration and it is found that extrapolation from the first two cycles supplies almost exact results.
