<jats:title>Abstract</jats:title><jats:p>Double eccentrically loaded cross‐sections with failing tension zone occur both in foundation engineering and in masonry building. The case of walls or columns loaded with double eccentricity by a normal force was no longer covered under the global safety concept of DIN 1053‐1 and is thus not normally considered in practice. With the transition to the semi‐probabilistic safety concept, verification of the cross‐section at the limit state of loadbearing capacity is performed near or at the failure state. This also made it necessary as part of the introduction of EN 1996‐1‐1 to introduce a verification for double eccentrically loaded cross‐sections. The present article considers the non‐linear stress distribution in double eccentrically loaded cross‐sections and the resulting position of the neutral axis. The described process is numerically robust and can be implemented with little effort for the analysis of masonry as an Excel spreadsheet.</jats:p>
