1.0 PDH / 0.1 IACET CEUs

Shear lugs are part of an anchorage system that transfers shear loads from the structure into concrete. This SEU Session will provide a brief review of the responsibilities of the design engineer as it relates to shear lug design, followed by a comprehensive review and comparison of the design guidance provided in AISC Design Guide 1 and ACI 318. Emphasis will be made on the information not contained in these publications, but that should be considered when designing a shear lug connection. During the presentation, speaker Barry Arnold will include his real-world experiences with the design of shear lugs and emphasize the importance of the steel and concrete engineers working together to find the most efficient and effective solution that will satisfy the strength and performance requirements.

Learning Objectives:

  • Outline the structural engineers’ (both the concrete and structural steel) responsibility when designing shear lugs.
  • Identify what information is not contained in the applicable codes but must be considered in the shear lug design.
  • Summarize the failures in communication, coordination, and the contract documents that may lead to unsatisfactory results.
