## 5 Discussion and Conclusions
More detailed analyses are necessary to test the capability of the modified method, to detect and quantify damage on high-rise buildings governed by a flexural behavior. New numerical analyses will be performed considering both new models for infilled panels and non-rigid beam-column joints [54]. In this paper, only the fundamental mode of vibration has been considered, but in the future it would be necessary to apply this approach to also consider the contribution of higher modes to the structural damage process (nonlinear field) during an earthquake.
