Abstract: Past earthquakes prove that adobe vaults, as traditional roofing systems for adobe architecture
located in hot and dry areas, play a significant role in the seismic behaviour of adobe
buildings. This paper reports the results from a geometrical survey carried out on 60
traditional adobe vaulted houses from the city of Yazd, Iran, followed by a simplified seismic
assessment. To this end, a reference vault combination is considered as representative of the
sample. Limit analysis theory implemented in Block2D software, is employed to carry out the
numerical analyses. Results indicate that parameters such as vault span, vault rise, supporting
wall thickness and mechanical properties of adobe masonry have significant influence on the
safety factor.
