Sensitivity Analysis of Large Unit Spiral Case for Different Reinforcement Arrangement


Article Preview

A numerical model for spiral case of hydropower station is built. The contact is considered and the sensitivity analysis for different reinforcement ratio is analyzed. The impact of different ratios on structure is studied. The stress and mechanical characteristics of steel bar is analyzed. The contact status is taken. The rational reinforcement ratio range, the process and evolution regularity of concrete cracks from microcosmic aspect to macroscopic aspect are obtained.
