Experimental study of 3-ply laminated glass beams subject to in-plane loads

In this study, nineteen 3-ply laminated glass beams of 1.0 m span with different and interlayer types were tested to failure. Annealed generally failed in shear facture, whereas toughened displayed lateral-torsional buckling (LTB) response, a bow-shaped out-of-plane deflected shape significant bending. The experimental failure loads had scatter for nominally similar beams, highlighting the variability as material. have been compared design predictions LTB from published methods, it was found that many existing methods consistently over-estimate capacity some cases by more than three times experimentally determined load.
