Zusammenfassung: | Optimized design of structures requires reduction of cost and also the fulfillment of technical specifications of security. Structural optimization methods has been inserted in this context in order to make faster and allow the obtainment of possible and satisfactory solutions, which can provide more economical structures. However, besides the economic gain, the use of these optimization techniques in a structural project allows to consider the factors related to the environmental impacts from process, as well as in the post-project and structural design processes. In this sense, this work proposed a mathematical model for the optimization of steel-concrete composite beams in order to minimize the monetary cost with materials and environmental impact, using the Harmony Search optimization method, which is a metaheuristic method based in analogy to the process of obtaining the best musical harmony. The model has been based on improvements in the structure of the Harmony Search optimization method, proposed by Medeiros and Kripka (2017). The discrete variables were the dimensions of the steel sections and the thickness of the cooperating slab of the steel concrete composite beam. The analyzes followed the recommendations of Brazilian standards for steel composite structures (ABNT NBR 8800/2008) and for welded steel I profiles (ABNT NBR 5884/2013). The proposed model has been implemented in the Fortran programming language. In order to prove the effectiveness and applicability of the proposed model, as well as the Harmony Search method, a series of analyzes has been carried out with different configurations of steel-concrete composite beam, aiming to provide guidelines that make the use of these systems more rationalized. In general, the Harmony Search optimization method was efficient in the search for optimized solutions, as well as important considerations on the optimization of the monetary costs with materials and environmental costs of steel-concrete composite beams were obtained from the examples developed. |

Os métodos de otimização de estruturas se inserem nesse contexto a fim de agilizar e permitir a obtenção de soluções possíveis e satisfatórias, as quais podem proporcionar estruturas mais econômicas. Contudo, além do ganho econômico, o uso dessas técnicas em um projeto estrutural permite considerar os fatores referentes aos impactos ambientais gerados nesse processo, bem como nos processos posteriores ao projeto e a concepção estrutural. Nesse sentido, este trabalho propôs um modelo matemático para a otimização de vigas mistas aço-concreto visando a minimização do custo monetário e do impacto ambiental, utilizando o método de otimização Busca Harmônica, o qual consiste numa meta-heurística desenvolvida em analogia ao processo de obtenção da melhor harmonia musical. O modelo foi baseado em melhoramentos na estrutura do método de otimização Busca Harmônica (Harmony Search), propostos por Medeiros e Kripka (2017). Foram consideradas como variáveis discretas, as dimensões dos perfis de aço e a espessura da laje colaborante do conjunto viga mista aço-concreto. As análises seguiram as recomendações das normativas brasileiras para estruturas de aço e mistas aço-concreto (ABNT NBR 8800/2008) e para perfis I de aço soldados (ABNT NBR 5884/2013). O modelo proposto foi implementado na linguagem de programação Fortran. Para comprovação da eficácia e aplicabilidade do modelo proposto, bem como do método de Busca Harmônica, foram realizadas uma série de análises com diferentes configurações de vigas mistas aço-concreto, a fim de fornecer diretrizes que tornem o uso desses sistemas mais racionalizado. De maneira geral, o método de otimização Busca Harmônica mostrou-se eficiente na busca pelas soluções otimizadas, assim como importantes considerações sobre a otimização dos custos monetários e ambientais de vigas mistas aço-concreto foram obtidas a partir dos exemplos desenvolvidos.Universidade de Passo FundoFaculdade de Engenharia e Arquitetura – FEARBrasilUPFPrograma de Pós-Graduação em Engenharia Civil e AmbientalKripka, Moacirhttp://lattes.cnpq.br/7554233520986997Tormen, Andréia Fátima2025-05-07T14:28:27Z2019-04-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfTORMEN, Andréia Fátima.
