“…Therefore, stair and lift shafts were omitted. The building is composed of four floors, which have a rectangular base of 22x17.5m, reaching a floor area of 385m 2 . The floor slab under study corresponds to floor 2 and it is here that the alternatives are modelled.…”

“…However, this structural element consumes huge amounts of energy and material resources compared to other elements that make up the whole structure such as foundations, columns, beams, etc. As consequence, when designing a structure, importance must be given to the optimisation of the floor slab through its characteristics variables such as: material of the vaults, height of the floor slab, type of joists etc [2]. In this way, it can have a direct impact on the economic level.…”

The aim of this research is to optimise a waffle slab for a reinforced concrete structure of a multifamily residential building. For this modelling, CYPE structural software has been used, as well as its respective economic and environmental database for the subsequent analysis. The optimisation of the floor slab has been achieved through various study alternatives, with the modification of its most characteristic parameters such as the type of concrete used, geometric distances of the various elements that make up the floor slab, as well as the material used for the coffer. All of this gives rise to a series of floor slab alternatives that allow a subsequent economic analysis to be carried out. This shows variations of up to 10% in the cost depending on the features of the floor slab. After this analysis, an environmental comparison of the alternatives is carried out by means of a life cycle analysis (LCA) of the floor slab, for which the results are significant with variations of 37% in kg of CO2 -equivalents emissions from one alternative to another. Through this research, it is possible to establish which parameters are the most important and have the greatest relevance when designing a floor slab. All of this, taking into account their economic and environmental impacts.
