No. of bitstreams: 1 146739.pdf: 1653652 bytes, checksum: 0a6b6d6a73a627ccf3fb2219729d7379 (MD5) Previous issue date: 1978-01 / Introduz a linha de pesquisa da alvenaria armada de tijolo cerâmico vazado, objetivando o comportamento dessas estruturas à compressão, nos estados-limites de utilização e de rotura. Executados com os tijolos furados de barro mais comuns nas construções, quinze pilares de seção quadrada foram ensaiados até a rotura, sendo adotados como parâmetros de variação a quantidade e categoria das barras de aço. A análise dos resultados é feita por diagramas e quadros comparativos dessas peças em serviço, no primeiro estado-limite e próximo à rotura. Definiram-se os diagramas característicos e de cálculo da alvenaria e da armadura passiva e a fórmula para verificação da compressão axial, e limitou-se o consumo de argamassa para esse tipo de alvenaria armada. / Starts a research line on reinforced air brick masonry, to study objetive the conduct of these structures under compression, at service limit and ultimate limit states. Fifteen columns of square section, built with air bricks usually used in constructions, were tested until the rupture point. The quantity and the category of reinforcing bars were used as parameters for variation. The analysis of the results were done using comparative diagrams and tables of these structures at service, at the first limit state and near the rupture point. The masonry and reinforcing bars characteristics and design diagrams and the axial compression verification formula were completely defined.
