Low-Cost Reinforcement of Earthen Houses in Seismic Areas

[Most text quoted from the referenced article shown below.] Vernacular earthen houses located in seismic areas are at risk because of their inherent structural vulnerability.

Zigzagging the barbed wire would provide more attachment points, … Read more
