SMAR 2024 – 7th International Conference on Smart Monitoring, Assessment and Rehabilitation of Civil Structures An Innovative Monitoring Strategy of Ancient Temples made of Rigid-Block Structures Luigi Petti a, *, Carmine Lupo a , Tiziana D’Angelo b , Paolo Dallocchio c , Duilio Guizzetti c a Department of Civil Engineering, University of Salerno, Via Giovanni Paolo II, 84084, Fisciano, Italy b PAEVE, Archaeological Park of Paestum and Velia, Ministry of Culture (MiC), Via Magna Grecia, 84047, Capaccio Paestum, Italy c Leica Geosystems S.p.a, Via Codognino 10, 26854, Cornegliano Laudense, Italy Abstract The need to preserve ancient monumental architecture finds crucial support in innovative methods and technologies that can improve our understanding of the buildings' structural health, promoting proactive maintenance. In this respect, an innovative experimental monitoring strategy has recently been developed and applied to the Temple of Athena in Paestum (Southern Italy, ca. 500 BC), in the frame of a joint research project by the Department of Civil Engineering (DICIV) of the University of Salerno (UNISA), the Archaeological Park of Paestum and Velia (PAEVE) and Leica Geosystems S.p.a. (LGS). The monitoring activities aim to support an in-depth assessment of the behaviour evolution of the columns on the East façade of the temple, where a crack pattern was recognized on some drums that were struck by a thunderbolt in the 70s. The monitoring strategy involves wireless sensors to record the relative distance between the abacus of columns and stylobate, as well as tilts with the abacus as the reference point. Correlation analyses on the data and signal processing based on Fourier theory are also employed. This paper describes the experimented monitoring strategy and discusses its preliminary results. In particular, the adopted analysis allow to investigate the structural response of ancient monumental architecture, considering the influence of weather conditions on measurements. © 2024 The Authors.
