A joint U.S.-Japan cooperative earthquake engineering research program produced a series of papers published as 13 chapters in this volume. Included are: Static tests on shear walls and beamcolumn assemblies and study on correlation between shaking table tests and pseudo-dynamic tests, Construction and instrumentation of the full scale specimen, Comparison between the reinforced concrete test structure and design requirements from U.S. and Japanese Building Codes, Testing procedure and preliminary test results of a full scaleseven story reinforced concrete building, testing, repair and strengthening, and retesting of a full scale seven story reinforced concrete building, inelastic behavior of the seven story building, Analysis of the full scale seven story reinforced concrete test structure, medium scale wall assemblies: Comparison of analysis and test results, Full scale tests of beamcolumn joints, Scale model tests of Structural components and assemblies, and Earthquake simulation tests of scale models.
