, the designer must either reduce bar spacing or increase the cross-sectional area of steel ( Ascap A sub s ), reducing the working stress ( σssigma sub s ) of the bars. 8. Summary of Geotechnical Checks (EN 1997)

To protect internal steel reinforcement from moisture corrosion, design crack widths ( wmaxw sub m a x end-sub

National Annexes (NA) specific to the country of construction must always be consulted, as they provide geographically dependent parameters, partial factors, and specific calculation choices. 2. Geometric Definitions & Modeling Approaches

For geotechnical uplift scenarios (), favorable permanent weight factors may drop to , while destabilizing groundwater actions are scaled by Serviceability Limit State (SLS)
