The dataset represents one of the most complete datasets and in-depth investigations publicly available of an instrumented building subjected to a design-level earthquake. This dataset contains detailed damage data from a ductile reinforced concrete building with prestressed precast hollow-core floors. The building investigated was located in Wellington, New Zealand. The damage investigation was conducted in 2019. Such detailed damage data makes this dataset a valuable resource to researchers investigating different aspects and parameters related to the seismic performance of ductile reinforced concrete moment-framed structures. Specifically, the dataset could be used to validate non-linear dynamic numerical models of reinforced concrete moment frames, improve assessment criteria for buildings within this archetype, correlate structural demands derived from both instruments and numerical models to observed damage levels, artificial intelligence training database for concrete damage related algorithms, and further data interrogation of laser scans.
