These provisions are mainly based on building linear responses and they distribute strength among LFRESs by static equilibrium based on predefined stiffness. An alternative approach for designing asymmetric buildings is using proper configuration of centers. Proper configuration of centers is a promising technique to control asymmetric buildings torsional responses. To use this method in seismic design, one has to find centers proper configuration and then distribute strength among LFREs such a way that results to that proper configuration. In this study a new methodology for designing asymmetric buildings is proposed. This method instead of using traditional static equilibrium, distributes the strength freely among LFREs, then strength of some LFRES are adjusted in a way to shift centers to their proper locations. To evaluate the method against traditional torsional provisions, some building models are designed by both traditional and proposed method. A comparison of nonlinear dynamic responses of these models displays the ability of proposed method for limiting building torsional responses.
