The standard gives the minimum steel thicknesses of the sections for each type of use, the mathematically determined widths of load distribution for the various static systems and the relevant effective spans. It includes general principles for the areas of shear with the necessary calculations, details of deformation and requirements concerning the physics relating to construction.
