Tested for Strength and Safety

Connect-EZ’s products are meticulously tested in the field to ensure that they exceed American Concrete Institute standards for connecting tilt-up wall panels to foundation (ACI 318 (’08) 16.5.1.3 sub-paragraph B) and for making connections between panels. Tests are performed using full-size panels in field conditions that are identical to installation environments. All Connect-EZ products exceed ACI standards and are proudly manufactured in the USA to meet the most stringent conditions and provide the safest connections – all with no field welding!

PA-12 Testing

PA-12 Testing Highlights

  • Full-scale testing

  • Devices subjected to four tests: shear, in-plane, out-of-plane, and combined in-and-out of plane

  • Each device could resist 2.44 times nominal design strength in tension

  • Application of shear loads was limited to the shear capacity of the anchor and bolt alone
  • Shear loads were applied with no grout in the 1″ space between the bottom of the panel and top of foundation
  • In all cases, devices experienced only ductile reaction to loads

PA-EX Testing

PA-EX Testing Highlights

  • Full-scale testing

  • Devices subjected to four tests: shear, in-plane, out-of-plane, and combined in-and-out of plane

  • Each device could resist 1.86 times nominal design strength in tension

  • Application of shear loads was limited to the shear capacity of the anchor and bolt alone
  • Shear loads were applied with no grout in the 1″ space between the bottom of the panel and top of foundation
  • In all cases, devices experienced only ductile reaction to loads

SC-10k Testing

SC-10 Testing Highlights

  • Full-scale testing

  • Both SC-a and SC-b resisted 10 kips

  • This suggests that the larger bolt gauges in SC-b did not affect the capacity.

  • The larger connection plates and bolt gages in SC-b did not impact the capacity.
