- Synopsis:
- A simplified 1-mass 3-degrees-of-freedom model, named Equivalent Single-Story Model, is proposed for multi-story unsymmetric buildings with regular elevation and brace-type steel seismic control devices in this paper. In the examples, the nonlinear response of four and seven story unsymmetric frame building models with ductile structural walls rehabilitated by brace-type steel seismic control devices obtained from three-dimensional frame building model are compared with those of proposed models. The results show that the proposed simplified model can satisfactorily estimate the maximum story drift and the cumulative plastic ductility ratio of seismic control devices.
