  • Corrosion Protection of Metal Connectors in Coastal Areas

    Credits: 3 PDH

    PDH Course Description:

    This course explains the importance of using corrosion-resistant metal connectors and fasteners in the construction of coastal structures, areas using preservative-treated lumber, and any locations subject to contact with floodwater or windblown rain.

    Post-disaster assessments of wood-framed buildings following natural hazard events such as high winds, floods, and earthquakes have revealed that structural failures frequently occur at connections rather than in framing members. In coastal areas, where higher moisture and humidity levels exist and buildings are exposed to salt spray, corroded metal connectors and fasteners have been observed to contribute to the loss of an adequate load path. The loss of an adequate load path often results in damage to or failure of the structure. This course presents guidance on addressing and avoiding the corrosion of connectors and fasteners.

    Topics:

    • National Flood Insurance Program Regulations
    • International Residential Code
    • International Building Code and ASCE 24
    • Proper Connectors for Continuous Load Path
    • Light Gauge Metal Connectors and Corrosion
    • Causes of Corrosion in Coastal Areas
    • Exposure Classes for Connectors and Fasteners
    • Improving Corrosion-Resistant Materials and Coatings
    • Guidance for Connector and Fastener Corrosion Control
    • Summary of Best Practices for Corrosion Resistance
