In the context of the tempered laminated glass panels submitted to the wind’s action effect, such panels are commonly used in the construction of buildings’ facades, taking into account their notable resistance to mechanical actions while maintaining the characteristic of luminosity requested by the architectural options. This work approaches the characterisation of the structural behaviour of laminated glass panels punctually supported by bolts fixed on glass surface with structural adhesive. Each panel, fixed by means of 4 stainless steel articulated connectors, includes an EVASAFE® or PVB interlayer between the two foils of the laminated structural glass, being subjected to air pressure applied through the laboratory’s pressurised air system and controlled by means of a valve. The pressure value is obtained using a mechanically calibrated sensor connected to a specific software through a compatible datalogger. The data collected by the strain gauges/displacement transducers are compared with those provided by digital image correlation (DIC) equipment. The maximum stress is also calculated at the central point on each panel. The technology of instrumentation and data acquisition using digital image correlation presents advantages in terms of efficiency and reduction of error in experimental tests as long as the optical reliability is ensured, making it advantageous in the case of structural glass compared to the traditional methods for data acquisition. Four measurement points are displayed for the desired comparison. A good result between both technologies were obtained for displacements and strains on the critical points in that panels.
