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.
