Abstract:This work introduces a new alternative to obtain strut-and-tie models using the hybrid topology optimization method, which is already proposed in the technical literature and is refined here to use polygonal finite elements and accelerate the solution of the material nonlinearity problem. In this method, concrete is approached as a continuum, using polygonal two-dimensional finite elements, and steel bars as truss elements, using one-dimensional finite elements with two nodes. For a closer representation of re… Show more
