Barbed Wire Anchors for Seismic Regions

Barbed Wire Anchors for Seismic Regions

Patti Stouter has devised a new way of reinforcing earthbag walls in seismic regions. Cement mortar is inserted in some joints between bags to lock the barbed wire in place and increase tensile strength. Mortar isn’t needed between every bag, and most likely every course doesn’t need this extra reinforcement. Designers/engineers could strategically place the mortar only where needed. For instance, analysis might lead to reinforcing the joint on each side of each corner and the middle of each wall on a moderate sized house. This system is very efficient — each joint would use just one shovel of mortar. One option is to tie or cinch the lower and upper courses of barbed wire together (only where mortar is being applied) to better embed the wire and increase strength. You could also mound a little extra mortar on top to add additional strength.

Designers and engineers now have another very good technique to add to our ‘tool box’ of reinforcing earthbag buildings — none of which were available or published just a few months ago. Thank you Patti.

  1. Good information for the earthbag building and increasing interest. Living in a rainy and hot summer area and I need more information on how to build in that area. Where to find tubular bags. I bought small bags and put them in a small shed on the vacant plot. The bags were eaten by rats or mice. Most of them are avknh big holes.
