Title: The minimum steel consumption in beams according to the prescriptions of the NBR 6118-2003 code - case study
Author(s): S. L. G. GARCIA, G. SAVARIS, J. R. FERREIRA

Keywords: truss model, strut angle, shear strength, minimum steeel consumption.
Abstract:The Brazilian code, NBR 6118:2003, recommends the usage of truss models with strut angle variation (?) and tie angle (a) for the concrete beams design subjected to bending and shear force. This code allows the designer to choose between two design models of the shear steel: The model I, where the strut angle has the value of 45º and the portion of shear force resisted by the concrete Vc has a constant value, and the model II, where the strut angle varies from 30º to 45º, with Vc varying in function of the shear force calculation (Vsd) and the shear force resisted by the strut (VRd2). The stirrups angle varies from 45° to 90°. With the aim of helping the designers in the choice of optimum models and angles, the mentioned models were evaluated, in order to determine which of these models and (?) and (a) angles lead to a minimum consumption of longitudinal and transverse steel in simply supported beams, subjected to bending combined with shear, with distributed loading.
