Crack width form performs crack width calculations of rectangular cross-sections currently to EN1992-1-1 and BS8110. Serviceability limit state requires cracks within reinforced concrete structural elements to be controlled down to allowable width.

Calculation performs design of rectangular, T- and L-beam reinforced concrete beams to BS8110-1, EN1992-1-1 (Eurocode 2), or ACI 318 (2014/2019 editions). The design is based on the limit state / strength design method and the beam is designed for bending, shear and torsion. Detailing, deflection and crack control checks are included.
