ROLES OF LARGE STRUCTURAL TESTING FOR THE ADAVANCEMENT OF EARTHQUAKE ENGINEERING

摘要：

The paper touched upon three issues in earthquake engineering. First, the earthquake threat of Japan is briefly introduced, followed by a discussion on the critical needs of collapse characterization and performance verification. Second, benefits of large-scale structural tests are discussed in terms of the size effect, rate-of-loading effect, redundancy effect, and effectiveness of numerical analyses. These benefits draw a statement such that it is sensible to test structures in the full-scale instead of miniatures, as systems instead of members, loaded dynamically instead of quasi-statically, until collapse instead of mild inelasticity. Third, the development of E-Defense, a very large shaking table facility, is presented, and previous and ongoing research projects using large-scale test specimens are introduced.
