A simple window glass design chart

A recently published ASTM standard outlines procedures for determining the strength of glass products used in buildings as windows and cladding. The new standard uses structural mechanics relationships to define the strength of a wide range of products, including monolithic glass, laminated glass and insulating glass. While the new standard is thorough and accurate, it is also complex. The authors offer a simple approach to the design of these glass products that applies to most building conditions, leaving only the exceptions to be treated by the complex process.
