Question 1
In ACI 318 anchor design, what does the term 'characteristic bond strength' (τk) represent?
Correct Answer:
The 5th percentile bond strength from testing used as the basis for design
Question 2
Which failure mode for adhesive anchors involves pulling out a cone of concrete around the anchor?
Correct Answer:
Concrete cone breakout
Question 3
How does increasing the embedment depth of an adhesive anchor affect its tensile bond capacity?
Correct Answer:
It increases capacity because a larger bonded surface area develops greater total bond force
Question 4
When adhesive anchors are installed in a group, what design reduction factor must be applied?
Correct Answer:
A group effect factor (ψg) that accounts for overlapping stress cones
Question 5
What is the significance of the sustained load reduction factor for adhesive anchors under long-term tension?
Correct Answer:
Bond strength can creep under sustained tension, so a reduction factor lowers allowable sustained loads
