Abstract

Aging buildings and ever evolving design codes imply the need of implementing retrofit techniques to ensure the safety and functionality buildings under current operating loads as well as extreme hazard events. Fiber reinforced polymer (FRP) composites are being implemented in practice to retrofit existing buildings as a popular retrofit system because of their high strength, lightweight properties, minimal profile, and versatile application. There are standards that help the engineer implement an FRP retrofit of a building (e.g., ACI 440.2R). However, the current performance-based seismic design standards such as ASCE/SEI 41-17 do not provide guidance on modeling parameters and acceptance criteria of reinforced concrete retrofitted components including beams, column, and shear walls. This study develops a database of experimental tests of FRP retrofitted reinforced concrete (RC) shear walls, which contains over 200 test specimens from test programs performed across the globe. The database is organized to present the most important parameters and details in an accessible format. The database is an essential mean to fill in missing gaps of information for the practicing engineer by analyzing the responses of the walls and determining backbone curves and modeling parameters relevant to retrofitted shear walls.
