METAL DECK ATTACHMENT TESTING

Hilti deck fasteners are subjected to many small element and full scale test programs to evaluate their performance.

Small Element Connection Tests

Small element connection tests are used to determine fastener pullout, pullover and lap-joint shear strength and stiffness with sheet steel and base steel representative of typical construction. The data is analyzed and used in a predictive model to calculate the performance of the larger steel deck diaphragm assembly or system. These tests are conducted in accordance with the following standards:
  • AISI S905 Test Methods for Mechanically Fastened Cold-Formed Steel Connections
  • ASTM E1190 Standard Test Methods for Strength of Power-Actuated Fasteners Installed In Structural Members
  • ICC-ES AC70 Acceptance Criteria for Fasteners Power Driven Into Concrete, Steel and Masonry Elements
  • ICC-ES AC118 Acceptance Criteria for Tapping Screw Fasteners

Full Scale Diaphragm System 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:
  • 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
