This paper deals with the assessment of adobe structures using non-linear dynamic Finite Element (FE) analysis. Numerical simulation of adobe masonry follows a continuum approach and is based on brittle fracture concepts that are expressed through a damaged plasticity constitutive law. The selection of appropriate modelling parameters is hereby discussed. Spatial FE models representing a traditional single-storey dwelling, before and after the implementation of certain strengthening interventions which modify the roof diaphragm configuration, are developed. The FE models are subjected to time history analyses using a real time accelerogram from a past earthquake. Comparisons among the structures' seismic responses are made in terms of the predicted damage distribution, displacement capacity and overall lateral resistance. Useful conclusions regarding the effect that different roof diaphragm configurations may pose on the dynamic behavior of adobe structures are derived. Finally, critical issues that future research should address in order to enable the efficient computational analysis of earthen structures are identified.

“…Even if standardized testing methods for evaluating the unconfined compressive strength of cohesive soils are present in literature, they examine earthen materials from the scope of geomechanics rather than in the context of common building applications (Illampas et al, 2014).

“…Figure 12 shows the comparison of the stress-strain model derived in this study with the models proposed by Zhang et al [28], Illampas et al [29], and Adorni et al [30], respectively. Equation (8) reported in [30] was calibrated by experimental data from uniaxial compression test on earth blocks with the ratio of height to thickness β > 1.…”

Loading rate and specimen geometry are critical parameters used in simple compressive tests to determine the strength of earth materials. In this study, cubic and cylindrical unstabilized compacted earth block of different sizes were manufactured and tested in unconfined compression to investigate the size and shape effects on the compressive strength of earth materials under different loading rates. e correlation between the compressive strength of earth materials and the geometric parameters of the specimen was determined. e recommended loading rate and sample for testing the compressive strength of earth materials were given. Finally, a constitutive model for describing the stress-strain response of earth materials was proposed. is model modifies the defects of the constitutive equations suggested in previous studies and may be applied to the numerical analysis of earth structure.
