SAFETY COEFFICIENTS IN THE CONVENTIONAL THEORY AND THE LIMIT STATE THEORY

LOS COEFICIENTES DE SEGURIDAD EN TEORIA CLASICA Y EN TEORIA DE ESTADOS LIMITES

A comparison is made between the conventional theory and the semi-probabilistic theory by introducing the notion of "nominal safety", which is the ratio of the ultimate stress in a section of nominal dimensions to the stress in the same section under normal service conditions. The limit state theory gives lower safety coefficients, as the principle used is that of adequate quality control. The present tendency is for the safety coefficient values to vary as a function of the degree of accuracy of the calculations and of the level of material control and execution of the work. The coefficients obtained with the limit state theory do not conform to some official specifications for structural elements such as slabs, which are based on the conventional theory. /TRRL/
