A practical model frame of braced building frames for dynamic inelastic response analysis is proposed in this paper. This model frame consists of a subassemblage without any brace and one with braces. A twenty-story building frame, the corresponding model frame and the corresponding reduced shear building model are subjected to five recorded and simulated earthquakes for the purpose of investigating the accuracy of prediction of dynamic inelastic responses of the original building frame by this model frame. Numerical analysis is conducted by means of DRAIN-2D EERC program. It is demonstrated that the fundamental, second and third natural periods and eigenmodes of this model frame are very close to those of the original building frame. It is also shown that not only the distribution of maximum interstory drifts but also the level of maximum inelastic response of each member can be predicted with the use of this model frame.
