The flat jack test is one of the most applied investigation techniques in the field of cultural heritage conservation. The purpose of the experimental campaign presented in this paper was to assess the feasibility of the technique to measure the average compressive levels of stress in existing cob walls and determine their mechanical properties. It was observed that the single flat jack test tended to overestimate the average value of stress by a factor of two. Therefore, it is advised to apply a value of Ke ¼ 0:51 to correct the average compressive stress values obtained with the use of this technique.

Abstract
The flat jack test is one of the most applied investigation techniques in the field of cultural heritage conservation. The purpose of the experimental campaign presented in this paper was to assess the feasibility of the technique to measure the average compressive levels of stress in existing cob walls and determine their mechanical properties. It was observed that the single flat jack test tended to overestimate the average value of stress by a factor of two. Therefore, it is advised to apply a value of Ke ¼ 0:51 to correct the average compressive stress values obtained with the use of this technique.| File | Dimensione | Formato | |
