Concrete-Filled Steel Tube (CFT) Load Transfer Database

This page describes a database of experimental push-out tests on circular and rectangular concrete-filled steel tubes. The database is primarily intended to be used in the validation of analytical models and design procedures. The database is maintained by Mark Denavit's research group at the University of Tennessee, Knoxville. The database and associated MATLAB files are available for download at github (browse - download zip). Please contact Mark Denavit with any comments, corrections, additions, suggestions, or if you are interested in the original reports.

The data is separated based on cross section type:

To be included in the database, each specimen must 1) have obtained natural bond strength in a physical experiment; 2) be described in a published work (preferably a peer-reviewed journal publication); and 3) be capable of being accurately described by the fields in this database. The following were excluded:

The current count of specimens in the database is:
