Glass-aluminium facades in steel buildings. Analysis of their performance under dynamic loadings.
According to modern structural codes, non structural elements of buildings (as are e.g. glassaluminium facades) that in case of failure can cause risks to persons or affect the serviceability of the building have to be verified to resist the design actions along with their supports with regard to dynamic loadings (as are e.g. wind loading and earthquakes). The question however, is which methodology is the most appropriate and accurate to be applied in order to analyse the performance of such elements and in particular, of the complete glassaluminium facade systems during dynamic loadings. The present research work intends to propose a methodology that will provide engineers aiming to design glass-aluminium facades of steel buildings with the appropriate methodology regarding curtam-wall performance subjected to dynamic loadings. Within such a framework the curtain-wall systems are analyzed using modern and powerful finite element method analysis software packages. The dynamic analyses were performed for both seismic and wind loadings. The proposed methodology is illustrated by means of a numerical application. The glass-aluminium facades are in general analysed and designed in practice empirically. The present research work intends to contribute to a pilot methodology that will provide engineers aiming to design glass-aluminium facades with the appropriate insight regarding their performance under dynamic loadings and in particular, under wind loading and seismic actions. Different models were formulated in order to achieve the previously mentioned objective. The computed values are the deflections of the facade elements, since the most critical verification is the serviceability limit state control. These values are in good accordance with the restrictions dictated by Eurocode 9. More specifically, maximum deformation rises to 6.8 mm, whereas Eurocode 9 dictates that for glass-aluminium facades of mullion-transom type the value L/250 = 3000/250 = 12mm should not be exceeded.
