Abstract	BACCIN, A.G.C. (1998). Fundamentals of high-performance concrete and its application to columns design. São Carlos. Dissertação (Mestrado) Escola de Engenharia de São Carlos, Universidade de São Paulo. Many advantages not only an economical but also from a structural point of view are obtained when using the high-performance concrete (HPC), such as: reduction of element section, low porosity and permeability, high wearing resistance and less cost of maintenance. This has contributed to a growing use of HPC in several countries, among them: USA, Norway, Canada, England, France and Japan. In Brazil, HPC is being used in different kinds of construction work, although there are no existing standards yet. Procedures of the sizing and desing criteria, recommended by Brazilian standards, are still based in experimental results obtained with low-strength concretes. Given that, this paper presents a theoretical study on material components of HPC, the amount to be employed on preparation of those concretes and the existing differences on ways of production and quality control. Also studied are some mechanical properties of HPC, such as: compression strength, tension strength, elasticity modulus, strain-strength curve and Poisson’s ratio. Several recommendation are pointed out for columns design, such as: minimun rate of both longitudinal and transverse reinforcements, yielding strength, spacing and lay out of transversal reinforcement to provide adequate ductility of columns made with HPC. Lastly examples of design of columns based on American standard ACI 318-89 and British standard BS 8110 are given.
