To grasp the structural characteristics of tall multi-storey buildings subjected to lateral loads, a method of approximate analysis is proposed treating them as bar-like continuum structures which deformed under the action of not only shearing and bending but also warpng. By this method, tall wall-frame structures, such as frames with core wall and coupled shear walls, can be analyzed. The warping deformation gives more effect on the displacement at the top of core wall structures than those by bending and shearing deformation in many cases. The restriction of warping at the top increases the lateral rigidity of core wall structures. It has shown in examples that the calculated results are good approximation and the computing times are remarkably decreased by this method, comparing with the exact discrete analysis method. This method may be useful for preliminary design.
