EXPERIMENTAL RESPONSE OF A PRECAST INFILL WALL SYSTEM

摘要

Many reinforced concrete moment resisting frame buildings in seismic zones lack strength and ductility. A precast infill system may provide an economic advantage for the retrofit of these structures. In order to evaluate the performance of this type of system, a two-story nonductile frame was constructed and rehabilitated with a precast infill wall and post-tensioning system. Three tests were performed on the rehabilitated model structure to evaluate the overall system behavior, verify performance of connection details, and investigate the performance of post-tensioning used to provide column tensile capacity at the boundary elements of the wall. The behavior of the structure through its loading history is discussed and compared with design assumptions.
