Advanced Techniques for Evaluating Vulnerability of Urban Infrastructure by Integrating Multiple Evaluation Indexes

Synopsis 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.
