Weaving Barbed Wire Corners

Guest post by Patti Stouter about another low tech way to reinforce corners in earthquake zones. More methods are explained at EarthbagStructures.com: “Corners are one of the most vulnerable parts of buildings in earthquakes. Straight wall earthbag construction has not … Continue reading →

Barbed Wire Details in Seismic Areas

An engineer of note gave us some suggestions on how to improve earthbag corners in seismic areas. The engineer is concerned the barbed wire could shift in a quake. He felt that wire mesh anchors (4- 5 with 1″ long … Continue reading →

Seismic Resistant Gravel Bag Foundations

Yesterday’s post was about the earthquake resistance of earthbags. Today’s post illustrates what an earthquake resistant gravel bag foundation looks like and explains why this design is so effective. Gravel is an ideal material for this application because it’s durable, … Continue reading →

Reinforcing Steel Recommended Instead of Buttresses

This is another major announcement courtesy of Structure1.com. Instead of building buttresses, which tend to be time consuming and difficult to design correctly for earthquake zones, they recommend using the same specifications we reported earlier for reinforced earthbag walls in … Continue reading →

Attaching Shear Walls to Earthbag Walls

The specifications for reinforced earthbag walls in seismic regions from Structure1.com describe how to attach shear walls to earthbag walls. Properly built shear walls add a great deal of strength to earthbag structures, but are seldom discussed. I thought a … Continue reading →

Reinforced Earthbag Specifications

I am extremely happy to announce another major first for earthbag building. Precision Engineering has generously provided drawings and specifications for building earthbag structures in seismic areas to meet code. The documents have been combined into one 6-page PDF and … Continue reading →
