DE LA CRUZ, CLAUDIA JENNY et al. BEAM SHEAR TEST OF STRUCTURAL SELF-COMPACTING CONCRETE . Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.159, pp.35-41. ISSN 0012-7353.

This paper presents a series of tests performed in the Structural Technology Laboratory of the Escuela de Ingenieros de Caminos, Canales y Puertos de Barcelona (Department of Construction Engineering) from the Polytechnic University of Catalonia. The campaign included a series of tests of beams section "Double T" Self Compacting Concrete of low strength (HAC-RM) and a parallel series using conventional concrete (HC) of the same mechanical strength. Was observed compared to the structural behavior of shear beams with reinforced concrete and prestressed reinforcement pretesa and postesa, and both continuous isostatic structures. The results show a lower resistance to shear at SCC beams with frame steel active and passive. For beams with prestressed SCC and HC, the shear strength values were similar.

Palavras-chave : Low Strength Self-compacting concrete; Conventional concrete; reinforced; isostatic; aggregate interlocking; prestressed; shear strength.
