Abstract The effective stiffness-based optimal technique to control quantitatively lateral drift for composite frame- shear wall structure system subject to horizontal loads is presented. To this end, the element stiffness matrices are constituted to solve the compatibility problem of displacement degree of freedom between the frame and shear wall. Also, the approximation concept that can effectively solve the large scaled problems is introduced. And, displacement sensitivity depending on the section property relationships is considered in order to reduce the number of design variables and differentiate easily the stiffness matrices. Specifically, constant-shape assumption which is uniformly varying in size during optimal process is applied in frame structure. The thickness or length of shear wall can be changed depending on user's intent. The example of 20 story composite frame-shear wall structure system is presented to illustrate the features of the quantitative lateral drift control technique.
