This course explores recent developments in anchor design and performance under tension loading, including methods to enhance breakout strength, anchor behavior in narrow or retrofitted members, and the impact of anchor reinforcement. The case studies and experimental research highlight practical applications in structural and seismic contexts.

The contents of this course include three recorded presentations from the ACI 2024 Fall Convention:

• Increasing the Concrete Breakout Capacity by Increasing the Anchor Head Area by Don Meinheit, Simpson Gumpertz and Heger

• Investigations of the Concrete Cone Failure Load of Anchor Groups in Narrow Concrete Members Subjected to Eccentric Tension Loads or Geometrical Asymmetry by Akanshu Sharma, Purdue University

• Performance of Post-Installed Bonded Anchorages with Anchor Reinforcement Under Tension Loading by Deepak Suthar, Purdue University

1. Understand how increasing the head stiffness or plate size of single anchors can improve tension breakout capacity based on ACI and AASHTO code provisions.
2. Analyze the behavior of anchor groups subjected to eccentric tension in narrow concrete members and identify viable design solutions.
3. Evaluate the effectiveness of anchor reinforcement in enhancing the strength and ductility of post-installed bonded anchors under tension loading.
4. Assess the anchorage behavior and failure mechanisms in retrofitted beam-column joints using post-installed steel haunch systems under seismic conditions.
