Linear finite element modeling of three-dimensional solid structures is well established, easy to apply, and readily available to designers. In the application of linear analysis in the design of concrete structures, however, it is not intuitive how to dimension the steel reinforcement to carry the stresses developed by the applied tractions. In this paper, a methodology for the design of reinforced concrete solid structures is presented using stress analysis combined with limit design. The admissible stress domain is presented in terms of Mohr’s circles with solutions given for optimum reinforcement ratios, minimum concrete strength demand, and uniaxial concrete stress.
