Please see the attached moment frame elevation. ASCE 7-05 Paragraph 12.2.5.5 requires that a special moment frame be CONTINUOUS to the foundation. Does this frame meet the requirement, even though several beams at Level 3 will be simply-supported gravity beams?
In case you're wondering why...
I appreciate your responses.
Here's an example that illustrates the problem I'm running into:
Code: ACI 318-05
Single 2"-dia anchor embedded 20", located at center of 8'x8'x2'-thick footing.
F'c = 3000 psi
Edge distance = 48" on all sides
Effective Ca1 = max(48"/1.5, 24"/1.5) = 32" (influenced...
jmiec, D.5.2.1 and D.5.2.5 relate to tension breakout. My question relates specifically to the distance from the anchor to the free edge in the direction of shear.
I'm using the strut and tie procedure to design pile caps on 150-ton micropiles. In order to limit the stress on the nodal zones at top of piles (Section A.5.2), I'm forced to provide an 18.5"x18.5" bearing plate to develop the pile capacity. This is much larger than I'm used to seeing. A.5.2...
The commentary for Section D.6.2.1 states that shear breakout will not control for anchors that are "far from the edge." I'm looking for guidance on how far an anchor should be from the edge in order to neglect shear breakout. For example, I'm calculating a shear breakout capacity of only 50...
