An innovative point-fixing device of laminated glass for frameless glazing has been conceived of, where the polymeric interlayer, slightly extending beyond the edge of the glass plies in the proximity of the boarders, is bent at right angle & directly attached to metal clamps via the lamination process. This technology is made possible by a high-performance ionoplastic polymer with high elastic moduli, low viscoelasticity, & high glass transition temp.This paper reports the results of destructive tests on full size specimens under pressure loading. During the tests, one (or both) of the glass plies of laminated panels were broken to study their postcritical performance. In all cases, a noteworthy load-bearing capacity is maintained & sudden collapse avoided because, remarkably, the point fixing devices firmly hold the interlayer even after complete glass breakage.
