Glass Analysis under Extreme Loads
External glazing is critical to the safety of a building’s inhabitants and the protection of its economic investments during explosions, high-winds and other extreme events. A prior understanding of the performance of a structure’s glazing during such events provides options for upgrades and enhancements that will ultimately save lives and assets.
By applying the most advanced structural analysis technology in existence tody, ASI provides unmatched capabilities to analyze the performance of glazing subjected to blast, wind-borne debris, impact, and other critical loads.
ASI’s Applied Element Method (AEM) based technology is the only analysis method for accurately analyzing the behavior of glazing during impact and shattering. By being able to analyze and predict the linear, nonlinear, and failure modes of glass and its layers, ASI’s engineers:
- Provide solutions for protecting glazing systems against critical loads
- Analyze existing glazing systems against ASTM specifications, blast loads and impact
- Test interlayer, structure, lamination, and mechanical properties in a computer-environment, while the glass is still in R & D
- Collaborate with glass manufacturers to develop the most protective forms of glazing possible
- Run simulations on new glazing and laminate product lines
- Determine upgrades and retrofits for mitigating shattering glass
ASI’s analysis and simulations allow the teams responsible for protecting structures to:
- Investigate multiple scenarios that might compromise a glazing system (e.g. high winds, debris penetration, and blast)
- Reevaluate glazing purchasing decisions (e.g. Tempered vs. Annealed vs. Heat Treated)
- Identify and compare upgrades
- Consider a repositioning of critical infrastructure to safer locations
- Minimize the risks of shattering glass on the structure’s inhabitants
ASI models glazing systems to include details affecting the glass’s integrity when exposed to various loading scenarios. A typical model includes:
- Window system
- Laminate
- Reinforcement
- Glass thickness
