摘要：
Single steel-plate concrete composite (SSC) structures, with good impact resistance and high construction efficiency, have emerged as new solutions for nuclear power plant (NPP) containment. This paper presents a commercial aircraft impact analysis of a new SSC containment structure. Before obtaining more reasonable results from large-scale numerical analysis, small-scale models of the SSC local structure, SSC panel elements, and commercial aircraft were established and experimentally or theoretically verified. Based on these small-scale models, a complete model for SSC containment against aircraft impact was established. Parametric analysis was conducted to investigate the influences of various factors on the dynamic characteristics of the containment. The results indicated that while the influence of soil-structure interaction (SSI) effects is relatively minimal, lateral constraints from external plants should be considered. Considering the balance among steel consumption, economic benefits, construction quality, and efficiency, SSC containment is recommended for high-temperature gas-cooled reactors.
