Este trabalho apresenta o desenvolvimento de modelos físicos de correntes e molas empregados nos processos de busca da forma (form finding), comumente utilizados para a definição do padrão de corte em projetos estruturais de cabos de aço retesados. O trabalho objetivou examinar as singularidades de tal metodologia de análise e concepção estrutural, inicialmente elaborada pelo arquiteto alemão Frei Otto, e se baseou na literatura crítica acerca do desenvolvimento das tecnologias de sistemas de cabos de aço. Ao longo deste trabalho, foram investigadas diferentes possibilidades de materiais e métodos de medição dos modelos físicos, que tiveram a finalidade de fornecer dados de ordem qualitativa acerca do comportamento do sistema estrutural em questão, em situação de desenvolvimento de projetos. Com o intuito de avaliar a precisão e confiabilidade do modelo de correntes e molas, em paralelo, foram desenvolvidos modelos digitais por meio do método das Densidades de Forças. Por fim, os resultados obtidos por meio dos dois métodos de busca da forma foram comparados, buscando-se compreender as vantagens e limites de suas aplicações práticas.
