1 Appendix A EXAMPLES OF PERIMETER PANEL FLOOR TRUSS CONNECTORS The floor trusses were attached to the perimeter panels at the interior intersection of the columns and spandrels by different types of connectors. The following appendix displays photographic examples, taken by National Institute of Standards and Technology (NIST), of these types of connectors as observed on the panels.
