SEISMIC REHABILITATION USING INFILL WALL SYSTEMS
Abstract In seismic regions throughout the world, a large inventory of reinforced concrete structures exist that lack both strength and ductility. The economic impact resulting from a loss of these structures during a seismic event is enormous. Many facilities are vital in terms of their operational benefits. The functional capabilities of many of these facilities cannot be shut down or even suspended. Consequently, there is a great need for efficient, effective, and inexpensive rehabilitation strategies that are minimally invasive and minimize disruption to building operations. While a variety of techniques are available to meet these requirements, the use of an infill wall presents a significant advantage when attempting to minimize both costs and disruption. Furthermore, construction plays a vital role in the success of any rehabilitation scheme. This paper will evaluate infill construction techniques with a focus on a precast infill scheme. The retrofit of a two-story laboratory structure incorporating the precast system will be discussed. Due to the nature of the precast system, the performance of the connections is vital. Consequently, their design and construction will be highlighted. The effectiveness of this rehabilitation scheme will be demonstrated through the overall behavior of the structural system.
