The current paper compares experimental results obtained at different scales (from TAjoints to large scale 914mm by 1524mm) with the predictions of the analytical equations and FEA.
Modern free form glass architecture has become increasingly popular in the structural sealant glazing application, as demonstrated by many iconic building projects, such as Allianz tower in Milan.
The two case studies illustrate how the engineering of glass can fluctuate with design intent in unusual scenarios – when we cannot rely solely on conventional codes and standards to guide the analysis.
The paper will provide an overview of the currently applied engineering approach in the industry for curved hot bent glass in the absence of standards and codes.

The most obvious way to verify compliance of fenestration products with code requirements for structural strength under wind pressure loading, often based on commercial-grade requirements of the North American Fenestration Standard, is laboratory testing. However, when a specific project calls for non-standard configurations such as larger or smaller sizes, variations in framing configuration or higher wind pressure levels than those of the tested baseline assembly, it can be prohibitively expensive and time-consuming to test all such variations.
Accordingly, the Fenestration & Glazing Industry Alliance offers a standardized process for engineering evaluation of windows and doors, in the form of AAMA 2502-19, Comparative Analysis Procedure for Window and Door Products, an FGIA standard. Approved as a reference standard in the International Building Code, AAMA 2502 sets forth engineering design rules by which commercial products that differ from the test unit can be q
