Comparative analysis of the structural systems of blocks A and B of the architectural set of the Attorney General of the Republic of Brazil, Brasília, DF

Resumo

Oscar Niemeyer's work, recognized in the landscape of international architecture, has always attracted
the attention of architects and engineers to discover the dichotomy and paradigm that exists between structure and
architecture. Among the Works of Oscar Niemeyer of the 2000 ́s, symbol of the juridical order and the democratic
regime, the “Attorney General’s Office” stands out for being constituted by an architectural complex of six
buildings. The geometric forms of this complex are defining a monumental space represented by two main
buildings, realized by two constructive technologies and different structural solutions. The block “A”, supported
by a cable-stayed system, and the block “B”, supported by reinforced concrete pillars, demonstrates how the
structure is strongly linked to the design of architectural morphology. Through a structural analysis carried out by
the SAP2000 program, it was possible to identify the structural models that constitute the Attorney ́s project to
obtain numerical data that represent the innovation of constructing the same architectural object through two
antithetical conceptions. This study of the work in question allowed to understand the patterns that characterize
the formal aspects of the structural technology used by the genius of the Brazilian architect and the relative
constructive methods adopted.
