Because of high stiffness and small ductility in spite of high strength, reinforced concrete shear walls do not always have many advantages in the structural design of buildings. Hence, Deformable shear walls, i. e., walls with high strength, low stiffness and large ductility, have been required. From this background, the authors proposed the Deformable shear walls using the flexible connectors between steel frames and reinforced concrete walls. We carried out the static test up to failure of six wall specimens to examine the general behavior of such Deformable shear walls. Further, based on the test results, we established a system of elastic analysis of tall buildings with Deformable shear walls. For the analysis, frames are analyzed by the slope-deflection method, Deformable connectors are assumed as the springs, and the finite element method is applied to the analysis of the reinforced concrete walls. Comparison between results obtained by the analysis and the experiments proved that this method of analysis is reasonable. Using this method of analysis, we examined the relation among the frames and the Deformable connectors and the walls for the tall buildings, N stories with one bay. It is indicated that for the stiffness and the shear force the Eq.23 and the Eq.24 are in good agreement with those computed by the above method of analysis.
