- Synopsis:
- Nonlinear response of multi-story unsymmetric buildings regular in elevation with elasto-plastic seismic control devices under bi-directional excitation is discussed and the effect of elastio-plastic seismic control devices are examined. Then a nonlinear static procedure to estimate the maximum drift of multi-story unsymmetric buildings with elasto-plastic seismic control devices is presented and its applicability is discussed. The results obtained by the proposed procedure are compared with the nonlinear time-history analysis results, and satisfactory prediction can be found by the presented procedure.
