Stability and seismic vulnerability of the Stylite Tower at Umm Ar-Rasas

Research on the Stylite Tower at Umm Ar-Rasas, Jordan, reveals critical insights into its stability and seismic vulnerability, offering foundational data for potential retrofit interventions. The study employed in situ experimental tests, including Schmidt-hammer tests on stone blocks and passive seismic measurements, to analyze soil and structural material properties. Stability was assessed assuming an elastic-perfect plastic behavior in compression for masonry, while a push-over seismic analysis using finite solid element modeling with a Drucker-Prager yield criterion further evaluated its vulnerability. These findings provide essential guidance for preserving this unique historical structure against seismic risks.
