Sliding Stability

The 3-D finite element model of a concrete gravity dam’s spillway was established in this paper, and the elastic-plastic theory was applied, then the deformation and stress state of the dam under various working conditions were analyzed, it was prooved that the deformation and stress state of the dam were in normal condition. After solving the force of the dam foundation surface and taking full account of the complex geological conditions, the dam’s sliding stability was analyzed by capacity limit state design formula. The calculation results showed that, the stability parameter of the dam along foundation surface was bigger than 1.0, the dam’s sliding stability met the requirement.

State Criterion

This article analyses the conditions for the yield stress state of concrete subjected to generalised loads. For this purpose, a limit stress state criterion, initially developed for the assessment of magnesium and respective alloys, is here adapted and implemented as a simulation model to assess the structural integrity of concrete components. In fact, materials as magnesium and concrete exhibit a similar mechanical behaviour, presenting a non-symmetric limit state domain for biaxial stress combinations, where it is observed a considerably larger strength to yield or rupture in a compression stress state than in a tensile one. The Cazacu yield stress state criterion has shown to be an accurate and realistic model to define the ultimate strength, either of concrete and magnesium alloys, as mentioned. The Cazacu criterion was implemented in a finite element program as a ‘user-defined’ subroutine. The numerical validation of that criterion was carried out on adjusting its limit stress state points to corresponding ones obtained by experiments of standard tensile or compression tests of concrete test specimens.
