Abstract:This paper presents an overview of the requirements for deflection of beams and slabs in the draft Brazilian Code for concrete structures, NBR 6116:2000. Firstly, the Brazilian Code recommendations for deflection computations and allowable limits are described, and then these provisions are compared with those of section 9.5 of ACI 316-99. The paper also includes a numerical example to illustrate how the new proposals are applied to structural design. It is observed that the general criteria of the two codes are similar, but some differences are pointed out regarding minimum thickness requirements, load conditions, effective moment of inertia for continuous beams and the values of modular ratio, modulus of rupture and allowable deflections.
