Summary: | The subject of this work is the construction of bridges, infrastructure constructions essential to the transportation of people and goods, referring to the concern in the rationalization of designs and processes of bridge construction, focusing on reducing costs, consumption of resources and environmental impacts. The objective was to apply sustainability assessment techniques in the life cycle of small span bridge superstructures, proposing environmental and economic indicators to be integrated in the decision making process, aiming to mitigate the environmental impact, reduce the consumption of resources and minimize the costs in their life cycle. The study analyzed 405 small span bridges, starting at 6 meters up to 20 meters, of the following types: steel and concrete composite bridges; reinforced concrete bridges cast in loco; precast reinforced and prestressed concrete bridges, quantifying environmental impacts and costs through the Life Cycle Environmental Assessment and Life Cycle Cost Assessment, for the proposition of sustainability indicators for the construction of bridges, following the frontier of systems for the extraction of materials until the end of life (from the cradle to the grave). The guidelines of national and international standards were used, based on the Ecoinvent 3.5 database of 2018, the global reach method ReCiPe 2016 V1.1, and the SimaPro software version 9.0.0.32. In the results, it was observed the indication of the steel and concrete composite bridge with two P1 M(S) 2V steel beams as the one that causes less impact on the environment; the bridge superstructure of the steel and concrete composite model with P4 M(L) 2V rolled steel beams is the bridge that presents the lowest cost per m² for the lengths of 6m and 7m; the reinforced precast concrete model, P23 PMD 5V, is the most economical in the spans of 8m to 20m. In conclusion, it was observed that steel and concrete composite type P1 M(S) 2 V bridges and precast type P23 PMD 5V bridges can be indicated as the most efficient from the sustainability point of view. |

Objetivou-se aplicar técnicas de avaliação da sustentabilidade no ciclo de vida das superestruturas de pontes de pequenos vãos, propondo indicadores ambientais e econômicos para serem integrados ao processo de tomada de decisão, objetivando mitigar o impacto ambiental, diminuir o consumo de recursos e minimizar os custos em seu ciclo de vida. O estudo analisou 405 pontes de pequenos vãos, iniciando em 6 metros até 20 metros, dos tipos: pontes mistas aço/concreto; pontes de concreto armado moldadas in loco; pontes pré-moldadas em concreto armado e protendido, quantificando os impactos ambientais e custos através da Avaliação Ambiental do Ciclo de Vida e Avaliação do Custo no Ciclo de Vida, para a proposição de indicadores de sustentabilidade para a construção de pontes, seguindo a fronteira de sistemas da extração dos materiais até o fim de vida (do berço ao túmulo). Foram utilizadas as orientações das Normas nacionais e internacionais, com a utilização da base de dados Ecoinvent 3.5 de 2018, o método de alcance global ReCiPe 2016 V1.1, e o software SimaPro versão 9.0.0.32. Dos resultados, observou-se a indicação da ponte mista aço/concreto com duas vigas metálicas P1 M(S) 2V como sendo a que causa menos impactos no meio ambiente; a superestrutura da ponte do modelo mista aço/concreto com vigas laminadas P4 M(L) 2V é a ponte que apresenta o menor custo por m² para os comprimentos de 6m e 7m; o modelo em concreto armado, pré-moldada P23 PMD 5V, é o mais econômico nos vãos de 8m até os 20m. Na conclusão, observou-se que as pontes mistas aço/concreto do tipo P1 M(S) 2 V e as pontes pré-moldadas do modelo P23 PMD 5V podem ser indicadas como as mais eficientes do ponto de vista da sustentabilidade.Universidade de Passo FundoFaculdade de Engenharia e Arquitetura – FEARBrasilUPFPrograma de Pós-Graduação em Engenharia Civil e AmbientalKripka, Moacirhttp://lattes.cnpq.br/7554233520986997Milani, Cleovir José2025-05-07T14:28:43Z2020-02-18info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfapplication/pdfMILANI, Cleovir José.
