Regardless of the loading, anchor bolt type or base plate size and thickness,
the minimum edge distance to face of stem wall controls my design.
Min Edge Distance and spacing between anchor bolts dictates the concrete wall thickness.
for any 1/2 diameter A.B. min edge distance and min spacing is 4".
This makes 12" wide concrete stem wall requirement for two anchors.
Is there any solution for 8" thick stem walls with 2 A.B. positioned in straight row line?
Hello,
The minimum edge distance and anchor spacing requirements listed for each anchor is critical to adhere to each anchor’s testing and approvals. Generally, failure to meet these requirements may result in splitting of the concrete among other failure modes.
One option you may want to consider to try different anchoring patterns could be Hilti’s PROFIS Engineering Suite. For design help, many engineers consider using Hilti's PROFIS Engineering Suite software to perform calculations based on the specific conditions of the project. Click here to access the software from Hilti’s website. Hilti has several how-to videos to help users get started with the PROFIS Engineering Suite software. For additional information on the various design modules/methods, Hilti provides several on-demand Ask Hilti webinars on topics such as base plate design, anchoring to masonry, and anchoring to concrete-over-metal deck.
