Abstract
The seismic assessment of an existing reinforced concrete building designed to pre-1970s codes during a major earthquake focuses on investigating the global post-elastic responses of the building. The global post-elastic response of a reinforced concrete building can be studied based on the local post-elastic behaviour of the individual structural components.
In this study, simulated seismic loading tests were conducted on as-built reinforced concrete beam-column joint subassemblages in order to obtain the information on the post-elastic behaviour of as-built reinforced concrete components. Simulated seismic loading tests included two as-built full-scale interior beam-column joint units, four as-built full-scale exterior beam – column joint units and one retrofitted as-built exterior beam-column joint unit.
