Abstract
Earthbag construction is a sustainable, low-cost, housing option for developing countries. Earthbag structures are built of individual soil-filled fabric bags (i.e., sand bags) stacked in a running bond pattern. Once stacked, earthbags are compacted and the soil inside the bags is dried in-place to form earthen bricks. Barbed wires are placed between each course to affect shear transfer within the wall. Results of an out-of-plane load test on a full-scale earthbag wall are presented in this paper. The wall was subjected to out-of-plane pressure up to 3.16 kPa, which resulted in plastic deformations up to 50 mm. The wall did not collapse during loading. Wall behavior and force transfer mechanisms are discussed.

Summary
Adequate housing has been defined as being secure, habitable, affordable, safe, and culturally appropriate. Earthbag structures offer a sustainable, affordable housing option for developing countries These structures are comprised of individual fabric bags (i.e., sand bags) filled with soil and stacked in a running. Barbed wires are placed between each course to affect shear transfer between bags. This construction method was pioneered by Gernot Minke of Kassel University in the 1970s [2], and has received increased attention in recent years [2,3,4,5,6,7,8,9]. The research program presented in the current paper was designed to identify whether earthbag wall structures subjected to out-of-plane loading display similar behavior
