| Outline of Final Research Achievements |
FE model of steel concrete composite slab subjected to corrosion was verified. As the result, it was confirmed that the model could simulate appropriate behavior of punching shear failure of the slab. Parametric analysis of corroded steel - concrete composite slab subjected to punching shear was conducted by the FE program verified in this study. The distribution of cross sectional area loss of steel plate was used as a parameter. Corrosion distribution most influencing to punching shear capacity of the slab was confirmed from the results of analysis.

本研究において妥当性が確認された腐食合成床版のモデルを用いて，有限要素解析により腐食した合成床版の詳細な構造性能評価を行うことができる．また本研究におけるパラメトリック解析の結果として示した，押抜きせん断破壊に最も影響を及ぼす腐食分布は，目視点検結果を用いた概略性能評価に役立てることが可能である．ただし，実験等による検証が不足しているため，今後，さらなる検証の蓄積が必要である．
