A shake-table test of a 2-story full-scale low-damage concrete wall building was conducted on the multifunctional shake-table array at Tongji University to validate the system-level dynamic response of this type of building. The test building implemented state-of-art low-damage structural systems, including post-tensioned (PT) precast concrete walls, precast concrete frames with slotted beam connections, and a variety of energy-dissipating devices. The building was subjected to 39 separate earthquake tests, consisting of a range of structural design configurations and ground motions including different intensity records, far-field and near-fault records, and short- and long-duration records. The test data and documentation recorded throughout the project have provided a significant high-quality data set for improving understanding both global and local response of post-tensioning concrete wall buildings. The data set has been published and is publicly available. The methodology of the test documentation and data collection for each stage of the project are described, and a road map for navigating the archived data set is provided to support its future use.

Reinforced concrete members in structures are typically subjected to a combination of bending, shear and axial compression (tension) loads. A simplified bending-shear-axial compression (tension) interaction formula based on bending-axial compression, bending-shear and bending-axial tension interactions was proposed to obtain the strength envelope of symmetrically reinforced concrete members under bending, shear and axial compression (tension). The interaction formula is verified by a comparison with experimental data. A sample planar-frame calculation result indicates that the envelope can be used as a failure criterion in symmetrically reinforced components to determine the safety of the members and calculate the residual capacities of components under bending, shear and axial compression (tension).
