Reliability assessment of containment tangential shear failure

This report presents the latest developments of the reliability analysis method for concrete containments. In specific, the tangential shear limit state for reinforced concrete containments is described in detail. Also, the flexure limit state has been modified such that the strain of tensile reinforcement is limited. Furthermore, the variations of material strength such as concrete compressive strength and reinforcement yield strength are included in the reliability analysis by using the Latin hypercube sampling technique. Then, the reliability analysis results and fragility curves for two containments are presented.
