Elevado Presidente João Goulart: processo construtivo e sistema estrutural

Abstract

Designed by architect Luiz Carlos Gomes Cardim Sangirardi in 1968, during Mayor Paulo Maluf's administration in 1969, the Elevado Presidente João Goulart, known as "Minhocão," has sparked numerous discussions since its beginning. Comprising 90 main spans, 96 pillars, seven access ramps, and isostatic structures supported by eight longitudinal beams forming a grid structure on the pillars, the elevated road showcases a broad range of dimensions and construction methods. This research aims to present the construction process of this architectural structure, highlighting its geometry, materials used, and structural system through descriptive and exploratory approaches, utilizing data collection and analysis from literature, including documentary sources. It explains the construction process from the initial design to its completion, detailing stages, equipment, and techniques used, and presenting its geometric characteristics to contextualize the historical background of the project and construction of the Elevado Presidente João Goulart, known as "Minhocão," up to the present day. Additionally, it seeks to clarify the environmental, visual, economic, and social impacts caused by the structure since its construction, comparing traffic improvements in the region before and after its creation, and examining the potential effects of its deactivation. The research also highlights conservation aspects of the Minhocão, investigates and identifies the social and cultural practices and movements currently taking place in the area, and presents similar urban scenarios in other cities. It analyzes proposals and adaptations implemented to enhance the urban environment and improve the integration of existing viaducts.
