AASHTO Publications Bolted Connections (4 PDHs) TC3CN006-16-T1

This course offers professional development hours (PDHs). You will see the PDHs on your course completion certificate, which also serves as documentation of your attendance. PDH requirements vary, therefore, it is up to you to determine whether or not this particular course qualifies under your State or board requirements. Appreciation is extended to Hytorc, Division Unex Corporation for its assistance in the development of this curriculum. Course overview: Bolting is a common method of making connections and care should be exercised in their design, installation, and maintenance. This course is divided into two modules: installation and inspection. For both modules, it is suggested that participants have a basic familiarity with construction and mechanical principles. All participants in Module 2: Inspection should have mastered the principles taught in Module 1: Installation, and should have experience in construction inspection. Module 1: Installation is divided into four sections: • Topic 1: Structural joints, their types, and how they carry load • Topic 2: Structural fasteners and talks about their care and handling • Topic 3: Torque and tension and how they are measured and applied • Topic 4: Approved tightening methods and tools Module 2: Inspection is also divided into four sections: • Topic 1: Documentation and storage • Topic 2: Components of pre-job inspection • Topic 3: Calibration and testing • Topic 4: Verification of installation Training level: This training is recommended for the Transportation Curriculum Coordination Council levels II, III, and IV. Target audience: This training is designed for agencies and their industry counterparts involved in the installation and inspection of bolts and bolted connections on construction projects. Learning outcomes: Upon completion of the course, participants will be able to: • Explain the advantages of bolts in structural joints; • Identify the three structural joint types and discuss when each is used and the differences in how they are tightened; • Describe structural fasteners with their various grades, forms, finishes and coatings, and how they are matched, prepared for use, accounted for, stored and handled; • Explain the four accepted methods for achieving desired bolt preload and the relative advantages/disadvant ages of each; • Explain and give examples of the manufacturer’s certificates, shipping documents, storage requirements, and site records associated with structural fasteners; • Locate and interpret the appropriate industry standards for joint and fastener types and specifications; • Conduct and audit torque-tension and ROCAP tests and verify test records; and? • Explain the check points and how you would audit to verify proper assembly for the following tightening methods: turn-of-nut, torque control, DTI washers, and TC bolts.
