Abstract:
A system level shake-table test of a full-scale low-damage concrete wall building implementing state-of-art design concepts will be conducted on the multi-functional shake-table array at Tongji University as part of an ILEE-QuakeCoRE collaborative project. The 2-storey test building was designed with post-tensioned (PT) walls that provide the primary lateral-load resistance in both directions, in conjunction with a concrete moment frame predominantly resisting gravity loads. Different floor systems and wall-to-floor connections that have been implemented in constructed buildings in New Zealand were incorporated in the test building to investigate different design concepts and detailing. Level 1 consists of precast concrete double tees and a steel tray composite floor is used on level 2. Conventional wall-to-floor connections using a flexible link slab and isolating device-type wall-to-floor connections were designed in the longitudinal and transverse directions, respectively. A number of alternative energy dissipating devices were positioned at wall base or/and beam-column joints of the building. The test building will be subjected to a large number of tests, including different combinations of wall strength, energy dissipating elements, shaking direction, and ground motions. The tests will provide a rich dataset to verify design procedures and numerical models. The design of the test building is described in this paper.
