A seminar organized by CONSTRUCT-LESE will take place on the 5th of April at 14h30 in romm B034 and will host, as an invited lecturer, Prof. Enrico Spacone from the University "G. D'Annunzio" of Chieti Pescara, Italy. The seminar is entitled:
DEFINITION OF LIMIT STATES FOR SEISMIC RISK ASSESSMENT OF REINFORCED CONCRETE STRUCTURES
Although disseminated in a very short notice, it is believed this seminar will be of interest to many colleagues, as well as to graduate and undergraduate students.
Abstract: The seminar reports the results of an ongoing project on the evaluation of the risk of damage and collapse implicit in the design of code-conforming new RC structures. A set of 3-, 6- and 9- story buildings in five sites of increasing seismic hazard were designed according to the Italian seismic code. Multiple stripe analyses were run for 10 ground motion intensity levels, in order to compute the D/C failure rates. At first, the definitions of damage and collapse were based on global engineering demand parameters derived from pushover analyses. It is however clear that the definition of collapse is not unique, and different results are obtained depending on the collapse definition adopted. The seminar intends to present different approaches to collapse definition and their implications on the assessment of the structural response.
CV: Enrico Spacone received his BA degree in civil engineering from the University "La Sapienza" of Roma (1987), and his MS (1990) and PhD (2004) degrees in civil engineering from the University of California, Berkeley. He worked first at the EPF Lausanne (Switzerland) from 1987 to 1989 then moved to the United States. From 1995 he was Assistant and then Associate Professor at University of Colorado, Boulder. From 2001, he is Professor of structural engineering at the University "G. D'Annunzio" of Chieti Pescara, where he teaches structural design and structural analysis. He is also member of the faculty of the Centre for Post-Graduate Training and Research in Earthquake Engineering and Engineering Seismology (Rose School) of the University of Pavia. His main research interests are nonlinear modelling of structures under cyclic loads and assessment (both analytical and experimental) of the seismic response of masonry and reinforced concrete structures. More recently, he has expended his interests to include seismic risk evaluation at the urban scale.
