Adobe construction is becoming popular in the American Southwest, but has always been used for construction in many parts of the world. When US personnel move into an area, they often will temporarily occupy housing that is made out of adobe; therefore, it is necessary to understand the characteristics of such materials and building systems under blast. Therefore, the objective of this work is to characterize the mechanical properties of adobe to be able to model its response as a material type in structural elements. This research focused on evaluating the static resistance function of adobe walls, which was used for blast response calculations and modeling. An experimental program was conducted to evaluate the material and structural response of adobe materials and walls, as well as develop and evaluate possible blast retrofit designs. In this paper, material testing for shear, compression, and rupture properties and walls and wallettes under uniform pressure were evaluated. In addition, measured mechanical properties were used in a 3D finite element model and compared to the experimental results of the full-scale adobe wall systems. Blast response predictions and numerical models were verified using shock tube dynamic test results, and are presented in this paper.
