Análise experimental de pilares de concreto de alto desempenho submetidos à compressão simples / Experimental analysis of high strength concrete columns (60 MPa) under axial compression

Queiroga, Marcos Vinícios Mendonça de 30 March 1999 (has links)
O objetivo da pesquisa foi obter subsídios para o projeto de pilares de concreto de alta resistência, submetidos à compressão simples, com concreto de resistência média de 60 MPa. Este projeto faz parte de um plano mais amplo onde já se têm resultados experimentais que traduzem o comportamento de pilares moldados com concreto de resistência média à compressão de 80 MPa. Nestes constatou-se a participação isolada do núcleo de concreto definido pelo eixo da armadura transversal como seção resistente dos pilares. Na etapa experimental foram ensaiados pilares com seções transversais quadradas de 200 mm x 200 mm e retangulares de 150 mm x 300 mm. As alturas dos pilares correspondem a seis vezes a menor dimensão da seção transversal, portanto, 1200 mm e 900 mm, respectivamente. Nos modelos de seção quadrada, o valor médio das relações entre as forças últimas experimentais e as forças últimas teóricas, considerando a seção total de concreto, resultou igual a 0,82, indicando que a seção resistente não é a seção total. Por outro lado, a média das relações entre as forças últimas experimentais e as forças últimas teóricas, considerando apenas a área do núcleo limitada pelo eixo dos estribos, resultou igual a 1,21, o que mostra que a seção resistente pode ser considerada, no Estado Limite Último, como a seção do núcleo. / This research\'s aim is to obtain information for design of high strength concrete columns under concentrically loads with medium cylinder compressive strength of 60 MPa. This project belongs to a more extensive plan which already has experimental results that represent the behavior of columns performed with concrete with medium cylinder compressive strength of 80 MPa. In these models has been verified the independent participation of concrete core defined by the transversal reinforcement axis as resistant section near the ultimate load. In the experimental stage it was tested twelve columns with square (200 mm x 200 mm) and rectangular (150 mm x 300 mm) cross sections. The height of the columns corresponds to six times the smallest dimension of the cross section, 1,200 mm and 900 mm, respectively. The medium value of the ratios between the ultimate experimental force and the ultimate theoretical force, regarding the full concrete section, was 0.82, indicating that the resistant section is not the full section. On the other hand, the medium of ratios between the ultimate experimental force and the ultimate theoretical force, considering only the core area limited by the axis of the lateral reinforcement bars, was 1.21, what shows that the resistant section can be considered as the core section in the Ultimate Limit State.
