We propose this standard for engineering analysis of laminated glass lites for a broad range of section geometries (e.g., double, triple, and multi-ply laminated glass plies), loading, and boundary conditions based on effective thickness methodology. Since the introduction of Appendix X9 in E1300, a wider range of effective thickness methods have been developed for common laminated glass design applications, including cantilevered glass with two boundary conditions, fins, and plates. The E06.52 subcommittee determined that rather than extend the Appendix of E1300, a new standard should be authored, and subsequently referenced by E1300 and E2751 following its issuance.
This proposed standard builds on calculation methods included in recent European glass standards and provides the most comprehensive overview of effective thickness methods available for laminated glass analysis. Importantly, this standard addresses applicable evaluation methods for each combination of load and boundary conditions, and includes informative example problems highlighting similarities and differences.
The title and scope are in draft form and are under development within this ASTM Committee.
