Based on the Lectures given during the Eurocourse on Experimental and Numerical Methods in Earthquake Engineering held at the Joint Research Centre, Ispra, Italy, October 7-11, 1991
This book is focused on the seismic vulnerability assessment methods, applied to existing buildings, describing several behaviors and new approaches for assessment on a large scale (urban area). It is clear that the majority of urban centers are composed of old buildings, designed according to concepts and rules that are inadequate to the seismic context. How to assess the vulnerability of existing buildings is an essential step to improve the management of seismic risk and its prevention policy. After some key reminders, this book describes seismic vulnerability methods applied to a large number of structures (buildings and bridges) in moderate (France, Switzerland) and strong seismic prone regions (Italy, Greece). Contents 1. Seismic Vulnerability of Existing Buildings: Observational and Mechanical Approaches for Application in Urban Areas, Sergio Lagomarsino and Serena Cattari. 2. Mechanical Methods: Fragility Curves and Pushover Analysis, Caterina Negulescu and Pierre Gehl. 3. Seismic Vulnerability and Loss Assessment for Buildings in Greece, Andreas J. Kappos. 4. Experimental Method: Contribution of Ambient Vibration Recordings to the Vulnerability Assessment, Clotaire Michel and Philippe Guéguen. 5. Numerical Model: Simplified Strategies for Vulnerability Seismic Assessment of Existing Structures, Cédric Desprez, Panagiotis Kotronis and Stéphane Grange. 6. Approach Based on the Risk Used in Switzerland, Pierino Lestuzzi. 7. Preliminary Evaluation of the Seismic Vulnerability of Existing Bridges, Denis Davi. About the Authors Philippe Guéguen is a Senior IFSTTAR Researcher at ISTerre, Joseph Fourier University Grenoble 1, France
Ce ne sont pas les séismes qui tuent mais l’effondrement des constructions. C’est ainsi au génie parasismique, au travers de la réglementation, de concevoir des ouvrages résistants à l’aléa sismique dit réglementaire. Cependant, sachant que ces règles se sont améliorées en même temps que notre connaissance du phénomène naturel et des événements passés, force est de constater que la majorité des centres urbains est composée de bâtiments anciens, conçus selon des concepts et des règles de l’art souvent inadaptés au contexte sismique. Savoir évaluer la vulnérabilité des constructions existantes est donc une étape indispensable à une meilleure gestion du risque sismique et de sa politique de prévention. Après quelques rappels essentiels suivis d’exemples, cet ouvrage décrit des développements récents sur l’évaluation sismique de zones urbaines constituées d’un grand nombre de structures, dans des contextes à sismicité modérée (France, Suisse) ou forte (Italie, Grèce).
Structural Analysis of Historical Constructions contains about 160 papers that were presented at the IV International Seminar on Structural Analysis of Historical Constructions that was held from 10 to 13 November, 2004 in Padova Italy. Following publications of previous seminars that were organized in Barcelona, Spain (1995 and 1998) and Guimarães, Portugal (2001), state-of-the-art information is presented in these two volumes on the preservation, protection, and restoration of historical constructions, both comprising monumental structures and complete city centers. These two proceedings volumes are devoted to the possibilities of numerical and experimental techniques in the maintenance of historical structures. In this respect, the papers, originating from over 30 countries, are subdivided in the following areas: Historical aspects and general methodology, Materials and laboratory testing, Non-destructive testing and inspection techniques, Dynamic behavior and structural monitoring, Analytical and numerical approaches, Consolidation and strengthening techniques, Historical timber and metal structures, Seismic analysis and vulnerability assessment, Seismic strengthening and innovative systems, Case studies. Structural Analysis of Historical Constructions is a valuable source of information for scientists and practitioners working on structure-related issues of historical constructions
