Keywords: beams (supports) ; camber; concrete slabs; cracking (fracturing) ; creep properties;deflection; lightweight concrete; modulus of elasticity; moments of inertia; prestressed concrete;prestressing steels; reinforced concrete; reinforcing steels.
Presents a proposal for the control of deflections in which both minimum thickness and computed versus allowable deflection approaches are included. The format is that of a code, a commentary, and an example. The principal effects taken into account are those of cracking, continuity, compression steel in nonprestressed members, creep and shrinkage, the use of different weight concrete, and the degree of vulnerability of nonstructural elements.
