Eurocode 8 Part 1 provides criteria on the story drift ratio to limit the damage due to frequent seismic event. Although the regulation is simple, its practical applicability is impeded in lack of standard definition for classification of non-structural elements, including glass facades as well. The paper illustrates the behaviour and damage analysis of glass facades through the numerical analysis of a given configuration. Numerical model is developed for facade panels subjected to in-plane effects. The model is verified by experimental data. Parametric study is completed in order to find the parameters relevant to the deformation capacity corresponding to limited damage criteria level. Due to the large configurational variety, general criteria for facade systems cannot be provided, however, it is confirmed that, with proper detail design the required deformation capacity can be achieved and thus damages due to frequent seismic event can be easily controlled.
