Earthen structures made of adobe bricks are complex systems making the calculation of their behavior difficult, especially when they have to sustain lateral forces such as seismic. This paper presents a numerical investigation for the assessment of the structural response of unreinforced adobe masonry structures and how the installation of wooden ring beams contributes to their resistance. In the framework of the numerical investigation, finite element models were created to simulate the response of an adobe building with and without the implementation of wooden ring beams. The test building is located in Cyprus, in the South Eastern Mediterranean region which is a seismic area. The models were subjected to various earthquakes performing time history analyses for the calculation of pertinent displacements and stresses. The results show that the installation of the wooden ring beams vastly changes the response of the building not only in terms of the magnitude of the displacements and stresses but also their distribution pattern.
