A scaled model of five-storey irregular industrial building was tested on shake table. For seismic performance evaluation, the inelastic response is simulated by a simple 5-DOF shear model, which idealises columns as elastic-plastic model and braces as a combination of elastic-plastic and slip models. This model accounts for storey shear failure modes only. The results are compared with the test and a detailed member-hysteresis based analysis. As an improvement over shear models, a simple and innovative procedure is proposed for vibration mode-failure mode analysis for moment resisting frames, which can also account for failure modes other than the shear type. The plastic component of deformation is computed from the normality rule of plasticity. The proposed method is applied to a two-storey single-bay frame and results are compared with the member-hysteresis based analysis. This study indicates that the simplified models can provide fairly good estimates of response quantities for seismic performance evaluation for practical purposes.
