PARSEKIAN, G. A. (1996). Design of reinforced concrete slabs considering torsion. 116p. Dissertação (Mestrado) Escola de Engenharia de São Carlos, Universidade de São Paulo. In order to design reinforced concrete slabs considering all the resisting moments, including the torsional moment, it is necessary to know procedures to determine normal moments, in two chosen reinforcement directions, that are equivalent to the field of moments Mx, My and Mxy. In this work, two methods for orthogonal reinforcement are studied and compared and one for skew reinforcement is studied. In an attempt to consider the resistance of concrete to the torsional moment, the shear stress due to shear carried by concrete and the shear stress due to torsion carried by concrete and the ways of combining them are studied. Another aim of this work was to develop pre-processors to facilitate the process of modeling building floors in finite elements and one post-processor that permits the analysis of the results, using the concepts of this work. Using these softwares, a short study of simply supported rectangular slabs was made, in an attempt to evaluate the recommendations, found in the specialized bibliography, about the corner reinforcement necessary in these kinds of slabs. A comparison of the slabs design of one building floor, calculated using the yield line theory, using the finite element method without the torsional strength and using the finite element method with the torsional strength was also made.
