摘要

This mathematical research shows an optimal design for reinforced concrete T-section beams with straight haunches to obtain the minimum cost that considers the cost of concrete and the cost of reinforcing steel, and the constraint functions are the geometric properties (rules of current practice) and the equations provided by the ACI (American Concrete Institute) code. This model is shown in function of any type of vertical load on the beam, negative moments at support A and support B, and maximum positive moment. The paper presents a numerical example for seven different cases, and a comparison is made between the T-section beams and the rectangular section beams for the first four cases. The results show that T-beams are cheaper, lighter and have less volume than rectangular beams.
