Abstract

The objective of this paper is to provide an introduction to a recently compiled database of cold-formed steel framed shear wall tests and demonstrate the application of this database for improving the understanding and modeling of cold-formed steel framed shear walls. Over the last 20 years a substantial number of cold-formed steel framed shear walls have been tested under monotonic and cyclic conditions. These tests provide the support for the cold-formed steel framed shear wall provisions provided in the North American Standard for Cold-Formed Steel Structural Framing (AISI S240-15), the North American Standard for Seismic Design of Cold-Formed Steel Structural Systems (AISI S400-15), and the U.S. Seismic Evaluation and Retrofit of Existing Buildings standard (ASCE41- 17). The initial version of the database was assembled during the development of ASCE41-17. The database has recently been expanded to include additional tests, additional complete cyclic information from tests, additional fields regarding limit states and code predictions, and placed in a standardized format. The database consists of a central Excel spreadsheet, ordered plain text files for each individual test, and custom Matlab code for reading, processing, and plotting any desired subset of the database. As a new application of the assembled database the expected strength of cold-formed steel framed shear walls is explored. The information in the database is summarized herein, along with commentary on current code provisions, and areas of potential improvement and need.
