In‐plane Cyclic Response of Point‐fixed Laminated Glass Façade Systems: Experimental Findings on Seismic Performance

Point‐fixed glass façade systems (PFGFS) are widely used in modern architecture for their transparency and aesthetic appeal, yet their in‐plane drift capacity remains poorly understood. This paper presents full‐scale experimental results on 3x3 grid of laminated glass panels subjected to quasi‐static cyclic loading for two connection types. Results showed a progressive damage sequence starting with sealant softening and bolt rotation, followed by joint shear and glass fracture at in‐plane drift ratios near 2%. Both façades retained post‐fracture stability, with the laminated interlayer preventing panel fallout. Bolt rotation and washer yielding contributed to energy dissipation and drift tolerance beyond code limits.
