2 . Full scale diaphragm system tests ( cantilever tests )
Figure 2 : Small element connection tests
Full scale diaphragm system tests are used to determine the strength and stiffness of a larger steel deck diaphragm assembly directly . The data is analyzed and fit in a predictive model to address varying configurations of base steel , steel deck , specific fastener combinations and spans . These tests are conducted in accordance with the following standards and shown in Figures 3 , 4 and 5 .
• ICC-ES AC43 Acceptance Criteria for Steel Deck Roof and Floor Systems
• AISI S907 Cantilever Test Method for Cold-Formed Steel Diaphragms
• ASTM E455 Standard Test Method for Static Load Testing of Framed Floor or Roof Diaphragm Constructions for Buildings
