National Annex Load Inputs for Glass Design

Glass load checks often need more than a glass design standard. Load combinations and imposed loads may refer to Eurocode and project-specific National Annex sources.

Standards Referenced

Relevant references include EN 1990:2002, EN 1991-1-1:2002, and applicable project or local National Annex values.

Why It Matters

National Annex values can affect imposed loads, barrier loads, and the assumptions used in project-specific calculations.

Using VitraLab

VitraLab currently provides Irish National Annex barrier categories as default values, while allowing custom project values where another local National Annex or project brief applies.

Global Use

Users outside Ireland should review local National Annex requirements and enter custom values where the project basis is different.
