13. Punção em lajes cogumelo : estudo da retangularidade dos pilares
Eight reinforced concrete square flat slabs of reinforced concrete were tested. Slabs were 130mm thick with an 1800 mm side and were submitted to central loading, and the objective was to investigate the influence of column rectangularity coefficient. Column cross section dimensions (cmáx/cmín) varyied between 1 and 4, with a constant perimeter equal to 10

14. THEORETICAL AND EXPERIMENTAL ANALYSIS OF RIBBING FLAT SLABS IN REDUCED SCALE) / ANÁLISE TEÓRICA E EXPERIMENTAL DE LAJES COGUMELO NERVURADAS EM ESCALA REDUZIDA
The experimental analysis of structures of reinforced concrete supplies subsidies to the knowledge of the behavior of structural parts built with this material. Experimental analysis in reduced scale brings great advantages in relation to experimentation of real size models, since the amount of used materials is lesser and the physical conditions for laborat

15. Análise dos mecanismos resistentes e das similaridades de efeitos da adição de fibras de aço na resistência e na ductilidade à punção de lajes-cogumelo e ao cisalhamento de vigas de concreto. / Analysis of resistant mechanisms and similarities of the addition effect of steel fibers on strength and ductility to both the punching shear of flat slabs and the shear of concrete beams.
One of the main problems of flat slabs concerns the punching shear failure of the slab-column connection. This form of failure must be avoided, providing flat slabs with the best conditions for the development of yielding mechanisms of the flexural reinforcement before the occurrence of shear failure. The addition of steel fibers to concrete elements subject
