Abstract : Recent earthquakes such as Bhuj (2001) and Kashmir (2005) in India, and Umbria-Marche (1997) and L’Aquila (2009) in Italy, has spurred a renewed interest for studying the mitigation of seismic vulnerability of architectural heritage of these two countries. Mitigating the seismic risk of historical monuments is the major scope of an on-going multidisciplinary project involving the European Centre for Training and Research in Earthquake Engineering (EUCENTRE) in Pavia, Italy, and the Indian Institute of Technology Madras, Chennai, India. This project integrates aspects of seismic hazard, vulnerability and exposure to predict damage in selected typologies of monuments in Italy and India and defines a suitable risk mitigation retrofitting strategy. The Parthasarathy Hindu temple in Chennai and the Marte Ultore Roman temple in Rome were selected as case studies. The focus of this paper is on the definition of seismic input at the Italian site of Marte Ultore temple which is one of the deliverables of this joint project. The geotechnical characterization of the selected site has been conducted on the basis of non-invasive, geophysical field tests. The results of a probabilistic seismic hazard study available at the site were combined with ground response analyses to define the expected seismic input for the Roman temple. Local site effects have been assessed through 1D fully stochastic ground response analyses using for the object motion 7 real, spectrum-compatible records referred to respectively 475-year and 2475-year return periods.
