HEALTH MONITORING OF A MONUMENT AT ACROPOLIS USING AN EXPERT ACQUISITION SYSTEM AND WIRED OPTICAL SENSORS

Maintenance and preservation of monuments requires a balance between structural safety needs and respect to their architectural and historical value. Structural health monitoring (SHM) is a rapidly evolving methodology that has been increasingly implemented to maintain this balance. This paper presents the development and the implementation of a state – of – the art methodology using an expert acquisition system (EAS) and wired optical sensors to monitor evolving deformations during a period of twenty – one months on a monumental structure “Propylaea” of the Acropolis in Athens. The aim of the on-going SHM program is to monitor deformations and increase the structural knowledge of the behavior of the ancient monument in order to take any precautionary measures and avoid excessive deformations. 2651 Available online at www.eccomasproceedia.org Eccomas Proceedia COMPDYN (2017) 2651-2658 © 2017 The Authors.
