Abstract

Abstract

The failure mechanics of containment subjected to internal pressure were studied, and the functional and structural failure criteria were determined. Then, based on the concrete damage model, the nonlinear finite element analysis of the HPR1000 containment was carried out in order to research the failure process and determine the ultimate bearing capability of the containment subjected to internal pressure. The results showed that the damage and cracking first occurred near the equipment hatch when the inner pressure was increased to 2.5 times of the design pressure, indicating that the containment entered the plastic state. When the inner pressure was increased to 2.713 times of the design pressure, the steel lining began to be teared,which indicated that the containment reached the functional failure limit state. When the inner pressure was increased to 2.857 times of the design pressure, the concrete near the equipment hatch was damaged severely, and the failure occurred because of the considerable local displacement. It was illustrated that the containment reached the structural failure limit state.
