Abstract

Codes and standards developing organizations, such as American Society of Civil Engineers (ASCE) and American Concrete Institute (ACI), rely on experimental data to develop modeling parameters and acceptance criteria to be used in performance-based seismic design (PBSD) approach. This data is especially important when developing best practices using materials and techniques that are not covered in current PBSD standards, such as the use of fiber reinforced polymers (FRP) for seismic retrofit. Currently, guidance on the design of a retrofit system for reinforced concrete (RC) shear walls with FRP is missing from standards such as ACI 369.1 and ASCE 41. This paper describes the development of a database of FRP retrofitted shear walls that can assist in filling the information gap in the retrofit design guidance of RC shear walls. The main purpose of this database is to aid in the development of modeling parameters and acceptance criteria that standards developing organizations can adapt in order to provide guidance on the design of FRP retrofitted shear walls. The database includes over 200 experimental tests of shear walls from around the world, which can be filtered into categorized bins, like bins of walls with and without openings, or bins based on the premise of the test (i.e., pre-damaged and repaired vs. undamaged and retrofitted). The database will be available through the DesignSafe-CI platform in the near future, in a format that can be easily accessed and utilized by practicing engineers and researchers. This paper will conclude with recommendations for future experimental tests that would fill in the gaps in the data.
