<p><span style="color:rgb(0, 0, 0); font-family:verdana,arial,helvetica,sans-serif; font-size:12px">This paper considers the free vibration analysis of flexibly connected elastically supported stiffened coupled shear walls, having stepwise changes in width, by a simplifying method widely used in the past for the static analysis of similar structures [1]. This method comprises a convenient tool for the predesign computations related to the treatment of high-rise buildings. The method is called the continuous connection method (CCM). While the discrete structure is formulated as a continuous medium, the continuously distributed mass of the structure is discretized to a system of lumped masses for finding the corresponding mass matrix. After obtaining the standard frequency equation of the discrete system, the circular frequencies are determined in a straightforward manner and used to find the modes of vibration. The results obtained by the present method have been compared with those obtained using the SAP2000 structural analysis program and a good match has been observed. The method proposed in the present study, is twofold advantageous. Firstly, the data preparation is much easier than those of the equivalent frame and finite element methods. Besides, for quick trials of many different cases of a structure for optimization purposes, new versions of data can be obtained with much less changes in the present method compared to the other two. Secondly, the computation time of the present method is much less than those of the other two. Considering the foregoing two advantages, the present method can be used effectively for predesign or dimensioning purposes for high-rise buildings.</span></p>
