This paper is focussing on seismic assessment of Arg-e Tabriz in Tabriz city, Iran through microtremor measurements and FEM analysis. Arg-e Tabriz is a huge masonry structure which has been built in Ilkhanid ear (1336-1360 AD) in Tabriz, while it was the capital of in Iran in that period. Arg-e Tabriz was built in earthquake prone region and has experienced several strong earthquakes. Microtremor measurements were conducted to estimate the vibration modes and damping ratio of the structure. The finite element analysis was performed to compare the result of microtremor measurements and to assess the seismic safety of the structure.
Key Words : historical masonry structure, microtremor measurements, seismic response analysis
