A relação do projeto arquitetônico e das soluções estruturais com os custos da estrutura em um estudo de caso

Abstract

This case study aims to compare the costs and quantitative of materials of an architectural project in a structure with differentiated types of slabs. The types of study slabs were solid, ribbed with buckets, ribbed with buckets without beams (flat) and precast latticed. The development of the different structural models was done using the software Eberick 2018, from the modeling of the structure to the survey of quantitative and costs. All the calculation and sizing were done following as requirements of the norms NBR 6118/2014 - Sizing of concrete structures - Procedure, NBR 15200/2012 - Sizing of concrete structures of situations of fire and NBR 14432/2001 - Requirements of resistance to fire of construction elements of buildings - Procedure. After a brief theoretical foundation on the reinforced concrete, the types of slabs used in the project and about the software, it was demonstrated the methodology and the criteria adopted in the development of the project, also the main difficulties encountered with respect to the structural model presented, in the design and use of software. With the results at hand, it was possible to attest that the structural model composed of latticed slabs precast presented the lowest final cost, together with the lower steel and concrete consumption, for the conditions presented in the project, among all the models.
