Specifies classic solutions based on linearly elastic continuum, as well as prescriptive procedures used in common practice for analysis and design of slab systems. Deals with recommended practice in the selection and distribution of flexural reinforcement, and guide-lines to transmit loads from slabs to columns by flexure, torsion, and shear. The fundamental principles in this guide are applicable to all planar structural slab systems subjected to gravity loads and, in certain conditions, those combined with lateral forces.
