SUMMARY:
Determining the structural system of a building involves defining materials and arranging
elements in order to efficiently resist combinations of actions. In cases where steel or composite
rigid frames become inefficient, due to the high dimensions of the profiles or the difficulty and
cost of rigid connections; and bracings cause considerable impact to architecture due to the
obstruction of facades or circulation areas; shear walls systems are a viable alternative lateral
resisting system. However, in these buildings, the shear walls positioning and the layout in
the plan is most responsible for the torsional effects. In order to design a shear walls layout that
minimizes these effects, is compatible with the architectural plan, and satisfies the
requirements of the economy, strength, and rigidity, the designer performs an iterative and inefficient
process of trial and error, whose improvement of the solutions is dependent on previous projects
experience and intuition. To evaluate the use of a genetic algorithm in the conceptual design
of shear walls layout, a computational program was implemented that minimizes the structural
weight as a function of the layout, with restrictions to the resistant capacity, displacement, to
the effect of torsion, and the need for openings for the movement of people. The comparative
analysis carried out between four optimized models and a reference model, adapted from a real
the project resulted in a considerable reduction in the consumption of concrete, formwork, and steel
reinforcement; evidencing the benefits of introducing the optimal design process through the
genetic algorithm.
