anchor shaft design

anchor shaft design

anchor shaft design

(OP)
I have a guy anchor block(dead man) 3m below ground with 2 back to back chanels @ 39 degrees as shaft coming out of it.

The shaft is 2m above grond and 3m inside ground. I have a lateral force of 10kn at the tip of anchor shaft.

My question is: For calculating moments on the shaft, will I be considering length of shaft outside the ground only( 2m in this case) or will it be from the anchor block to the free end( 5m from block)?

RE: anchor shaft design

I doubt the ground would restrain the channels.  I would go to the block.  Is that what you meant?

UcfSE,

I was also thinking the same way but was not sure if soil would provide and grip or not.

Thanks.

RE: anchor shaft design

LOK,  I'm no geotech. or soils expert so I can't say with certainty that the soil won't help, but I have a feeling it won't.  When in doubt err on the conservative side.
