Impact assessment of construction methods and support structures on vibration levels of ancient reliefs

The preservation of ancient stone reliefs in museums is a substantial concern in the field of heritage conservation, especially for art that has been altered and removed from its original configuration. This case study was conducted in advance of active construction work, through a series of pilot (exploratory) tests, to assess vibration to which the art objects—ancient Assyrian reliefs and lamassu, dating to 883–859 BCE—were subjected. The study further explores the role of the gallery’s structural system and mounting details in transmitting vibrations to the art, supplemented by a numerical simulation of the relief dynamics. The present work serves as a useful reference for construction project managers and museum conservation specialists to help gauge the potential hazards caused by various construction means and methods. The study highlights the complex interplay between the art and the supporting structures that are used to stabilize, protect, and display the objects.
