New Guide for Effective Thickness Evaluation of Laminated Glass

1. Scope

The promotion of knowledge, stimulation of research, development and maintenance of standards and related documents for performance of buildings, their elements, components, including means and methods of fabrication and assembly; and the description, measurement, prediction, improvement, and management of the overall performance of buildings and building-related facilities. The work of this Committee will be coordinated with other ASTM Committees and other organizations having a mutual interest.


Effective Thickness; Laminated Glass; Architectural Glass; Structural Analysis


A range of effective thickness methods are available for the analysis of laminated glass in literature. The effective thickness method included in ASTM E1300 Annex X9 is limited to one pair of load and boundary conditions for 2-ply laminated glass. New effective thickness methods not included in ASTM standards are readily applied to further design applications, including multi-ply laminates, 4-edge supported plates, cantilevers, and glass fin buckling behavior.

This guide is intended to be a consolidated source of effective thickness methods referenced by ASTM E1300, ASTM E2461, ASTM E2751, a new Glass Guard practice, and a new Structural Glass guide for general design applications.

Proposed Scope:
This guide addresses Effective Thickness (ET) methods for the analysis of stiffness, deflection, and stress in laminated glass. This standard includes evaluation of laminated glass lite section properties related to design applications including, but not limited to, windows, guards, walkways, and glass fins. It addresses the simplified analysis of laminated glass for typical lite compositions for limited pairs of load and boundary conditions.

This practice does not address the capacity of laminated glass elements.

The title and scope are in draft form and are under development within this ASTM Committee.
