Sinclair Knight Merz was commissioned by Conacc Ltd to investigate the seismic load capacityof the TegTab product. Testing was undertaken at USG's Australasian manufacturing plant in Penrose, Auckland on 06/04/2006. Eighteen direct tensile tests of the TegTab connection were undertaken using USG's on-site tensile test rig. The TegTab system was found to perform adequately for use in perimeter-fixed suspended ceilings as a method for providing seismic restraint, subject to the load capacities and limitations noted on the full test report, with key points summarized in the Sinclair Knight Merz seismic integrity investigation.
A note on seismic requirements: When used with the Armstrong BERC or USG ACM7 clip, the Teg-Tab becomes essentially cosmetic and is not subject to seismic load requirements. Only when used IN PLACE of a seismic clip, requiring rivets, are Teg-Tabs subject to seismic code requirements. In this application, rivet right through the Teg-Tab.
