Abstract: 都市域に存在する多くの構造物の地震時における脆弱性を合理的に評価して危険度を低下させるための取り組みを,入力地震動評価の高度化,地盤・基礎の相互作用や非構造部材の応答特性に関する詳細な分析,長周期地震動による大型タンクスロッシング被害の軽減方策に関する各研究をすすめた。これらの各要素の結合により都市施設の地震時脆弱性の評価とそれに基づく防止対策を推進することができる。
It is essential for disaster prevention to quantify the earthquake vulnerability of urban infrastructures in consideration of their life cycle. As part of a five-year study on this subject, presented in this article are: the refinement of prediction of strong motions, examinations into actual performance of nonstructural components, rational evaluation of RC building structures in consideration of foundation-structure interaction, effects of total earth pressure on pile forces, and development of a systematic procedure for the estimation of life-cycle cost for large-scale lifeline network. Development of a sloshing reduction damper which consists of separation wall with slits installed in cylindrical tank.
