A mathematical model to compute the dynamic response of asymmetric shear wall-frame building structures is presented. The formulation is developed in detail for the case of one axis of symmetry. Also, the method is derived for the case of relatively uniform stiffining element with respect to height and it is based on the continuous approach. The lateral load resisting elements, as elastic continua, are combined by using the equilibrium and compatibility conditions to yield a coupled set of partial differential equations. Eigenvalues and eigenvectors are determined using numerical procedures and results are presented to show the natural periods and mode shapes for several practical structures. The total dynamic response of such structures subjected to earthquake ground motions is determined and results are presented for excitation due to several different earthquakes. The response results are compared with those obtained by using a static analysis with the objective of evaluating the adequacy of such static loading provisions and developing guidelines to define situations for which a detailed dynamic response computation is required.
