Abstract

Despite the fact that many times the choice of the structural system of a building is influenced by architectural especifications, constructives processes or regional capability, the structural engineering has to look for, according to the conditions, the alternative that guarantees the lower cost. This work aims to establish a relation between the material consumption (concrete, stell and formwork) and the structural system cost, among the structural alternatives in reinforced concrete. It will be analised a residential building, considering some options: two-way slab systems with beams, waffle slabs, precast slabs, flat plate waffle slabs and prestressed slabs with unbonded tendons. In the cost computation, for each alternative it will be considered: materials, equipment, construction time and workmanship. (AU)
