    Rationale

    Currently, ASTM E1300 permits the wide-ranging application of the effective thickness method presented in Appendix X9 to assess the load resistance (LR) and deflection of laminated glass for various support conditions. Recent papers have questioned the accuracy of the effective thickness method for applications other than simply-supported spans subject to a uniform load. Clarification for the accurate application of the effective thickness method and guidelines for the analysis of laminated glass is sought for design within the scope of ASTM E1300. Sections of the standard that instruct or permit the application of effective thickness method include: i) 6.3.2 Analytical Method to determine the Probability of Breakage in 4-edge supported glass ii) 6.2.8 Non-factored load charts for cantilevered laminated glass FIG A1.44 iii) X9 Method for Determining Effective Thickness of Laminated Glass for Analysis of Stress and Deflection
