GGU-CANTILEVER: Reinforced concrete design

Reinforced concrete is designed to EC 2 or, alternatively, to DIN 1045 (old) depending on the selected safety factor concept. Reinforcement is calculated for all wall element sections (see “Theoretical principles: Structural system”). The output is the section with the largest reinforcement.

The stem area above the footing is designed using the wall internal forces (see “Theoretical principles: Cantilever wall-Determination of wall loads for reinforced concrete design“).

The internal forces M and Q at the stem base/toe and heel intersections are calculated from the soil pressure and any surcharge present. The model concept is a cantilever. The normal force N results from the passive earth pressure.

The following sign rule applies to the spur and wall moments with reinforcement:
