Abstract: Massive concrete structures are structures for which the effects of hydration of the cementitious materials at the early ages can lead to cracking. The construction of such structures may follow a number of strategies that will determine its cost and schedule. These strategies aim to minimize the effects of the thermal stresses with the minimal cost for the contractor. The main variables that compose this optimization problem are: the height of the lifts, the period for construction of each lift, the placing temperature of the concrete, and the type of concrete. In this paper we present a strategy to solve this optimization problem based on a Genetic Algorithm. The main principles of the methodology are presented, as well as a case study that demonstrates the feasibility of this optimization procedure.
