Continuously reinforced concrete pavement (CRCP) performance depends primarily on early-age cracks that result from changes in temperature and drying shrinkage. Presented is the behavior of the CRCP due to the temperature change obtained by using a three-dimensional finite element model. The nonlinear effects of the bond-slip between concrete and steel and between concrete and base have been studied. Modeling for the curling effect and for the viscoelastic material characteristics also has been considered. The results from the two-dimensional and three-dimensional models have been compared to verify the possibility of using a two-dimensional model. From this study, it was found that crack width and concrete stress are dependent on the transverse steel arrangement near the edge (longitudinal joint), but they are almost independent in the interior of the slab. The tensile stress occurring at the top of the edge on the transverse steel location can be higher than that occurring at the top of the slab center. This represents the possibility of forming a transverse crack from the edge on the transverse steel location. The twodimensional model with the plane stress element gives results very close to those of the three-dimensional model, except near the edge.

Fuel Reprocessing

The nuclear fuel reprocessing or fabrication and power plants must be assessed for a set of various normal and accidental situations including explosions due to either operation hazards or malevolent acts. In order to evaluate the consequences of such an aggression in terms of damage to the plants and of radiological release in the environment, IRSN has launched a program including experiments and development of numerical models concerning the behavior concrete walls which are parts of plants. The purpose of this document is to present numerical simulations of chimney wall behavior when submitted to an internal explosion. The simulation uses a three dimensional model with a finite element code. The wave propagation is estimated including the reflection on the wall (the combination between the incident wave and the reflected waves, the attenuation). The detonation simulation is done in considering the walls at rest. The dynamic response of the structure is an estimation relating the time sequence in which the pressure is applied on the surrounding walls. The concrete and iron reinforcements have been taken into account. The stresses, strains and the percentage of cracks in wall are estimated.
