Contributions to experiment design in civil engineering research projects

The use of statistically designed experiments in research projects that involve the analysis of results from experimental programmes is not common in Civil Engineering. The statistical design of experiments allows for the refined analysis of data, obtained from the modelling of response variables. M...

Conduzir experimentos planejados estatisticamente em projetos cujo objeto de estudo principal são os resultados obtidos de programas experimentais ainda não é uma constante nas pesquisas em Engenharia Civil. O planejamento estatístico de experimentos permite realizar análises mais refinadas dos dados, por meio de modelagem das variáveis de resposta. Além disso, pode-se empregar projetos fracionados, o que possibilita trabalhar com diversas variáveis de controle, em diversos níveis, sem tornar o experimento oneroso e reduzindo o tempo de execução dos experimentos. O presente trabalho discute as vantagens do planejamento de experimentos, de forma a contribuir para melhorar a qualidade dos métodos de pesquisa em programas experimentais. São apresentados alguns exemplos de planejamento de experimentos na área de tecnologia de materiais de construção, indicando os principais benefícios alcançados. Além disso, são apresentadas as análises de dados obtidas a partir de experimentos completos e fracionados, concluindo-se que essencialmente a mesma informação pode ser obtida a partir de experimentos fracionados que seguem os conceitos estatísticos.
