Cost optimization of singly and doubly reinforced concreteT-beams

Abstract FRE

Cost optimization of singly and doubly reinforced concrete T-beams un-der ultimate design loads.

An analytical approach of the problem based ،)١٦ a minimum cost design criterion and a reduced number of design variables, is developed.

It is shown, among others, that the problem for-mulations can be cast intoa nonlinear mathematical programming for-mat.Typical examples are presented to illustrate the applicability (١٢ the formulations in accordancewith the designcode BAEL91-99 currently used in Algeria.

The results are then confronted to design solutions of reinforced concrete T-bcanis derived from current design practice.

The optimal solutions show clearly that significant savings can be made in the predicted amounts and costs of the construction materials to be used
