Structural Glass Calculator

This proprietary software, developed by Eastman in conjunction with industry glass experts, is based on the methodologies of European (EN) and international (ASTM and ISO) standards for glass characteristics and design.

This software is an online glass stress calculator that can be used for laminated glass designed with one-, two- , three- and four-side support. It has a simplified user interface that allows users to select the rectangular glass dimensions and the number of edge supports, and to enter their laminate configuration." The calculator was developed to allow users to compare a variety of different interlayer technologies to determine the best laminated configuration for specific glazing applications.
The calculator features glass thicknesses per individual lite ranging from 2.5 mm through 25 mm, and lites can be combined symmetrically or asymmetrically with Saflex interlayers. The software will perform calculations and provide a PDF report via email, detailing load resistance, glass stress and deflection for the requested configuration and providing the effective thickness for the single unit laminate from which the model was generated. The overall thickness and weight of the glass is also provided in the analysis.

Disclaimer

This software can be used to calculate load resistance of specified glass types exposed to uniform lateral and combined point and uniform loads of short or long duration subject to the following conditions:

1. The glass is free of edge and surface damage and has been properly glazed in the opening in conformance with the manufacturer's recommendations;
2. Glass was designed using the proper procedure for the application including but not limited to edge support, temperature, load type and duration.
3. The stiffness of members supporting any glass edge shall be sufficient that under design load, edge deflections shall not exceed L/175, where L denotes that length of the supported edge.
4. The non-factored load values for laminated glass are representative of test data and calculations performed for polyvinyl butyral interlayer at temperatures between 0ºC (32ºF) of 80ºC (176ºF).
