Hello,

I am developing Pre Eng Building Standard submittal log. It seems to me straight forward. some time it worth to have input.
Thanks in advance for you input.

and I add and subtract as the project requires... can be used for a guide...

In my experience designing foundations for these buildings (in the southeast), the length and style of the anchor rod below the column base plates was not specified by the building engineer.

Below the base plate, only the rod diameter and loads to be transferred at that location were tabulated by the building engingeer (and maybe the steel grade of the rod) so that the engineer of record could design the foundation.

I'm sure there are other acceptable delivery methods but any rod embedment lengths provided by the building enginer would not have been meaningful since the building engineer was not typically aware of the concrete coverage limitations on the footings or the configuration of supplemental reinforcement.
 
CAB...

that's why I stipulate, "PREFABRICATED METAL BUILDING SYSTEM SUPPLIER SHALL SUPPLY ALL ANCHOR RODS, NUTS AND WASHERS TO SECURE THE BUILDING TO THE FOUNDATION. ANCHOR RODS ARE TO BE DESIGNED FOR ALL HOR AND VERT LOADS"

Have run into problems with these guys before... My general notes are a compilation of problems and errors accumulated over the last 40 years <G>

in that case i think this is a regional distinction.

in areas governed by wind, the anchor rod capacity is highly dependent on concrete coverage, rod length, concrete strength, and the configuration of the embedded end (hooked or hex head). this is especially true if the building design relies on wind columns.

some type of supplemental reinforcement in the foundation is almost always needed to achieve the resistance transmitted by the rods when there is a near slab edge. also if you are designing a horse barn or arena where there is no slab then it is unlikely that the building engineer/suppliers anchor rod design will work.

typically i think that all of these elements cannot be properly considered by the supplier's engineer and should be described on the EOR's foundation plan. in my opinion, the suppliers drawings should only show the anchor rod's diameter and grade, not the length or the configuration of the embedded end.



 
I have anchor rod and concrete notes, too... that cover conc strength, anchor rod material, min embedment and use only heavy hex head/nuts... I specifically exclude 'J' or 'L' anchor rods.
