          <datacite:description descriptionType="Abstract">研究成果の概要（和文）：地震荷重をうけるコンクリート部材を対象に、地震後の残留ひび割れ幅を算定する手法を、実験的および解析的検討から考案し算定式としてまとめた。また、ひび割れ幅と鉄筋腐食の関連性について実験を行い、ひび割れ内部の塩化物イオン量および腐食程度とひび割れの関係について検討し、ひび割れ幅としては0.2mm程度が腐食程度の大小を決定する一つの目安となることを示した。研究成果の概要（英文）：The method to estimate residual crack width on concrete members suffered earthquake load was studied by experimental and analytical investigations and the calculation formula to calculate residual crack width was derived. By experimental study the relation between crack width on the surface of concrete member and degree of corrosion on steel bars , Cl- ion concentration are studied. 0.2mm more over crack width caused increasing Cl- ion concentration in the cracking surface of concrete and degree of corrosion of steel bars equipped in  concrete.</datacite:description>
