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 reinforced concrete beam to BS8110-1. The design is based on the limit state method and the beam is designed for bending and shear. Detailing and deflection checks are included.
