“…Both fs and shear modulus (G) showed relatively high scattering, where fs varied between 0.54 and 0.83 N/mm 2 and G varied between 1260 and 2146 N/mm 2 . Details on mechanical testing are reported in a previous study [8]. The cob samples failure occurred with the initiation of a main crack at the middle of the samples, which progressed towards the supports in diagonal direction.…”

“…All parameters showed relatively high scattering, where fs varied in the range of 0.37-0.64 N/mm 2 , shear strain at the maximum shear stress (γs) varied in the range of 5.6-10.7 mm/m and G in the range 311-634 N/mm 2 . Details on mechanical testing are reported in a previous study [26]. The results of the diagonal compression tests are listed in Table 2.…”

“…TSRCM is often used in the numerical modelling of historical constructions, where the compressive behaviour of masonry is in general represented with a parabolic relationship [40,41]. However, this relationship was shown to be excessively stiff and incapable of representing the large non-linear behaviour of earthen materials [8,42].…”

“…In last decade several studies were carried out to numerically model the behaviour of earthen materials under static [7,8,9,11,12,13,14,15,16,17] and under pseudo-dynamic loading [18,19,20]. This article presents a comparative study on the numerical modelling of three different earthen materials under static in-plane loading.…”

“…As with other engineering problems in which fracture has to be introduced, it may be necessary to change the numerical modelling paradigm to allow discontinuity, e.g. to use XFEM, and there is recent work of just this nature with EC materials in mind [18].…”

Challenges in treating earthen construction materials as unsaturated soils

et al. 2016

Abstract. Earthen construction is a loosely defined term covering both the materials and methods for creating structural components from mixtures of subsoil, often with the addition of chemical or mechanical stabilisers. There is evidence of Man creating earthen structures for thousands of years, and there are many world heritage sites containing earthen structures, some of which present issues in terms of conservation. In some parts of the world there is a growing market for new-build earthen structures and a key issue here is the lack of design codes. Since these materials are composed mainly of particulates and water it is natural to regard them as geotechnical in nature, where friction and the presence of water have a key influence on material properties, however until very recently this was not the case, with earthen construction materials regarded as weak concrete or masonry. In this paper we examine these opposing views and discuss the issues associated with regarding these materials as unsaturated soils. The paper is illustrated with outcomes from research at Durham University carried out over the past ten years.
