Abstract:Past test databases included a mix of bridge and building, standard and substandard columns, and reported parameters that might not be consistent with current codes or required in a bridge design. To achieve the current project goals, it was necessary to collect test data specific to modern RC bridge columns. A new performance database has been developed in the present work that includes all the key geometrical, material, and force-displacement properties of RC bridge columns designed with modern codes (especially those following seismic detailing). All parameters were collected following the current "AASHTO Guide Specifications for LRFD Seismic Bridge Design" definitions. Furthermore, displacements (drifts) at six different damage states as defined in this project were included when the data was available. The new database is built upon the work by Ghannoum et al. (2015), which included test data published up to 2008. Nevertheless, all substandard and/or building columns were removed, the definitions were updated to be consistent with current AASHTO SGS, and new parameters were added suited for seismic/bridge design. Furthermore, more than 100 new circular and 30 rectangular columns were added. The refined and updated RC bridge column database currently includes 222 circular and 68 rectangular columns. Two spreadsheets, one for circular and one for rectangular RC bridge columns, were developed each including more than 30 parameters per column. The definitions are also provided. The total size of the described zip file is 368.9 KB. Files with the .xlsx extension are Microsoft Excel spreadsheet files. These can be opened in Excel or open-source spreadsheet programs.
