Cette publication propose un inventaire des principaux acteurs qui contribuent ou peuvent contribuer à définir une politique migratoire pour la Belgique ; elle fait aussi le point sur leurs prises de position récentes. Quel est par exemple le point de vue de la FGTB sur une régularisation ? Que pense la FEB d’une nouvelle migration économique ? Que dit le Conseil des Femmes sur l’accueil des primo-arrivants ? Et bien d’autres encore. [less ▲]

The paper is given of an extended model for concrete in compression at elevated temperature that incorporates elastic, plastic and creep strain as a function of temperature and stress history. The mechanical strain calculated as a function of elastic strain, plastic strain and thermal induced strain. The thermal induced strain is relative independent compared to dependence of Young’s Modulus by load history. Actually the term comprises elastic, plastic and (pure) transient creep strains as we will show. A comparison is given between experimental results with cylindrical specimens and calculated results.

In this paper, numerical tests made in stainless steel thin-walled elements, using the program SAFIR, will be presented. In order to make these simulations, two main changes in SAFIR were made: i) the program was changed in order to deal with the stainless steel 2D material properties to be used with shell elements and ii) the possibility of the program to take into account residual stresses in shell elements was introduced. The stainless steel stress-strain relationship at high temperatures, was based on the one presented in part 1.2 of Eurocode 3 [1], which has no initial linear branch as the case of carbon steel. The hardening rule to be used on the shell element formulation could not be exactly established without an approximation of the Eurocode 3 constitutive law [1]. Due to the fact that the SAFIR procedure to take into account the residual stresses consists in transforming them first into residual strains and adding them after to the other initial strains [2], it was necessary to implement a procedure that took in consideration the nonlinearity of the material stress-strain relationship. The paper shows the influence of the residual stresses on the ultimate load bearing resistance of thin-walled stainless steel structural elements in case of fire. [less ▲]

Complex analytical procedures are often required to prove the non-compliance with a specific legislation. In the case of a small overlap of the limit, integration of the method uncertainty in the decision-making process is essential. The decision rule proposed in Wallonia, Belgium, for the non-compliance of waste incineration plants with the EU limit value for PCDD and PCDF emissions is presented. The method uncertainty was estimated annually over 6 years from duplicate measurements using two top-down approaches. Depending on the congener, the standard uncertainty varies from 30 to 85%, with a good correlation between calculations. The analytical contribution was estimated using a bottom-up evaluation. The impact of the sampling step was deduced from the whole estimation and represents more than 80% of the total uncertainty budget. No optimisation is foreseen at this time because of practical field constraints. Based on the average fraction of each congener, the uncertainty associated with the measurement result has been established and shows a high stability over the years. Using this value, a guard band has been calculated and will be proposed to the regulatory body. [less ▲]
