Summary

TLDRThe Connector Laboratory in Pleasanton focuses on developing innovative wood-to-wood connection products. This video showcases tests on the ITS hanger and HDU hold down, emphasizing the rigorous data-driven approach in product development. Key highlights include load testing for structural integrity and durability under extreme conditions, including simulated hurricane forces and corrosion tests in a salt spray booth. The lab maintains high standards for safety and effectiveness, showcasing the commitment to creating reliable construction solutions that significantly enhance building safety.

Takeaways

  • 🔬 The Connector Laboratory in Pleasanton specializes in developing products for wood-to-wood connections.
  • đŸ› ïž Significant effort goes into creating small steel components for construction, ensuring quality data for effective product development.
  • 📊 The I TS hanger is a top flange hanger tested for its load capacity when attached to a wood header.
  • ⚖ During testing, an actuator applies load to determine the ultimate capacity and measures deflection at each stage.
  • đŸ’„ The test showed no damage at 3,000 pounds, but ultimate failure caused the wood to split and the part to slip off.
  • 🌀 The HD U hold down is tested for overturning restraint in shear walls, simulating uplift forces.
  • 🔄 The testing setup was inverted to push down on the hold down to evaluate its capacity under hurricane conditions.
  • đŸŒĄïž Pressure-treated wood samples are tested at 120°F and 90% humidity for several days to assess performance.
  • 💧 A salt spray booth evaluates different coatings on products, exposing them to 100% humidity and a saline mist.
  • 🌍 Simpson's product development efforts aim to enhance safety, support customers, and contribute to global safety improvements.

Q & A

  • What is the primary focus of the Connector Laboratory?

    -The Connector Laboratory specializes in developing products for wood-to-wood connections, specifically testing steel components used in construction.

  • What is the purpose of the ITS hanger being tested?

    -The ITS hanger is a top flange hanger designed to connect to a wood header and is tested to evaluate its load-bearing capacity.

  • How is the load applied during the ITS hanger test?

    -An actuator applies a load to the ITS hanger until it reaches its ultimate capacity, while recording the deflection throughout the process.

  • What happens to the wood during the ITS hanger test?

    -During the test, the wood eventually splits and fails, demonstrating the ultimate failure point of the connection.

  • What is the function of the HDU hold down being tested?

    -The HDU hold down is used in shear walls to provide overturning restraint, ensuring stability against uplift forces.

  • How is the hold down test set up?

    -The hold down is anchored to a test bed with a large steel plate, and the test involves applying uplift forces by pulling on a wood post attached to the hold down.

  • What environmental conditions are maintained during the pressure-treated wood test?

    -The test maintains a temperature of 120 degrees Fahrenheit and 90% humidity for several days to simulate real-world conditions.

  • What is the purpose of the salt spray booth mentioned in the transcript?

    -The salt spray booth is used to evaluate different coatings on products by exposing them to a 5% salt concentration in high humidity to assess rust resistance.

  • What does Simpson aim to achieve through its product development and testing?

    -Simpson aims to make the world a safer place by developing reliable products and supporting customers with training and education.

  • Why is it important to measure deflection during the tests?

    -Measuring deflection helps determine the structural integrity and performance of the connectors under load, ensuring they meet safety standards.
