Keywords:
vigas, metálicasAbstract
Este artigo tem por objetivo analisar a capacidade resistente de vigas bi apoiadas em aço constituídas de perfis tipo I laminados de abas paralelas com dois eixos de simetria, sendo dotadas de emendas com parafusos de alta resistência do tipo ASTM A325 de diâmetro 19 mm, estando os modelos solicitados por esforços de flexão simples. Todas as ligações das vigas resistiram ao ensaio à flexão, não sendo constatada nenhuma ruptura nos parafusos e nem na chapa de ligação, apresentando carga de ruptura entre 73% para a viga V3L e 82% para a viga V1L com relação à viga de referência VREF.
