The building was subjected to simultaneous three-dimensional shaking on the E-Defense shake-table in Japan, using recorded ground motions from the 1995 Kobe earthquake. The excellent performance of the test building in the wall direction of response, exhibiting minimal damage and no residual deformations, confirms that UPT walls are a viable alternative to conventional reinforced concrete (RC) structural walls. In addition to providing experimental evidence of seismic performance of UPT walls incorporated into a building system, the tests provided valuable insight into issues typically not addressed in component-level experimental studies, such as the role of the floor diaphragm, influence of component interactions, and contributions of three-dimensional responses and torsion. As evidenced by the E-Defense test building, these effects need to be considered to obtain realistic estimates of lateral resistance and displacement demands. The tests also provided a wealth of data against which design methodologies and analytical models for UPT systems can be benchmarked. An analytical model of the building in the wall direction was developed and experimental results in this direction were used to assess the ability of the model to capture the dynamic responses and interactions of unbonded post- tensioned structural systems. Correlations between analytical and experimental results were satisfactory for a range of global and local responses, and key aspects of the interaction between components such as framing action and beam elongation effects were adequately reflected in the model.
