This book is focused on the seismic vulnerability assessmentmethods, applied to existing buildings, describing severalbehaviors and new approaches for assessment on a large scale (urbanarea). It is clear that the majority of urban centers are composed of oldbuildings, designed according to concepts and rules that areinadequate to the seismic context. How to assess the vulnerabilityof existing buildings is an essential step to improve themanagement of seismic risk and its prevention policy. After somekey reminders, this book describes seismic vulnerability methodsapplied to a large number of structures (buildings and bridges) inmoderate (France, Switzerland) and strong seismic prone regions(Italy, Greece). Contents 1. Seismic Vulnerability of Existing Buildings: Observationaland Mechanical Approaches for Application in Urban Areas, SergioLagomarsino and Serena Cattari. 2. Mechanical Methods: Fragility Curves and Pushover Analysis,Caterina Negulescu and Pierre Gehl. 3. Seismic Vulnerability and Loss Assessment for Buildings inGreece, Andreas J. Kappos. 4. Experimental Method: Contribution of Ambient VibrationRecordings to the Vulnerability Assessment, Clotaire Michel andPhilippe Guéguen. 5. Numerical Model: Simplified Strategies for Vulnerability SeismicAssessment of Existing Structures, Cédric Desprez, PanagiotisKotronis and Stéphane Grange. 6. Approach Based on the Risk Used in Switzerland, PierinoLestuzzi. 7. Preliminary Evaluation of the Seismic Vulnerability of ExistingBridges, Denis Davi.

This book presents a set of probability-based tools for efficient uncertainty analysis and for seismic vulnerability and risk assessment of structures, and illustrates the use of these tools in evaluating the potential impact of future earthquakes that may occur in the New Madrid Seismic Zone on reinforced concrete frames in the Central and Eastern United States. Due to the lack of natural strong motion records in this low-to-moderate seismic region, synthetic earthquake ground motions developed in recent seismological research are used in nonlinear finite element-based time history analyses to determine the seismic demand on the gravity load designed (GLD) frames. Seismic fragilities that incorporate various sources of uncertainty are formulated for low-, mid-, and high-rise GLD frames, and are used in the performance appraisal of the building frame inventory in Memphis, TN. This fragility assessment indicates that traditional GLD reinforced concrete frames may not meet the life safety and collapse prevention performance objectives that are stipulated in recent building codes and guidelines for performance-based earthquake engineering. The intended audience of this book is researchers and professional engineers involved with the performance assessment of existing buildings for upgraded seismic resistance.

The present volume contains a total of 23 papers centred on the research area of Seismic Assessment and Rehabilitation of Existing Buildings. This subject also forms the core of Project SfP977231, sponsored by the NATO Science for Peace Office and supported by the Scientific and Technical Research Council of Turkey [ TUBIT AK ]. Most of these papers were presented by the authors at a NATO Science for Peace Workshop held in Izmir on 13 - 14 May, 2003 and reflect a part of their latest work conducted within the general confines of the title of the NATO Project. Middle East Technical University, Ankara, Turkey serves as the hub of Project SfP977231 and coordinates research under the project with universities within Turkey, e. g. Istanbul Technical University and Kocaeli University, and with partner institutions in Greece and the Former Yugoslav Republic of Macedonia: A few articles have also been contributed by invited experts, who are all noted researchers in the field. Altogether, the contents of the volume deal with a vast array of problems in Seismic Assessment and Rehabilitation and cover a wide range of possible solutions, techniques and proposals. It is intended to touch upon many of these aspects separately below. Earthquakes constitute possibly the most widely spread and also the most feared of natural hazards. Recent earthquakes within the first six months of 2003, such as the Bingol Earthquake in Turkey and the Algerian earthquake, have caused both loss of life and severe damage to property.

Rehabilitation of heritage monuments provides sustainable development and cultural significance to a region. The most sensitive aspect of the refurbishment of existing buildings lies in the renovation and recovery of structural integrity and public safety. The Handbook of Research on Seismic Assessment and Rehabilitation of Historic Structures evaluates developing contributions in the field of earthquake engineering with regards to the analysis and treatment of structural damage inflicted by seismic activity. This book is a vital reference source for professionals, researchers, students, and engineers active in the field of earthquake engineering who are interested in the emergent developments and research available in the preservation and rehabilitation of heritage buildings following seismic activity.

Many more people are coming to live in earthquake-prone areas, especially urban ones. Many such areas contain low-rise, low-cost housing, while little money is available to retrofit the buildings to avoid total collapse and thus potentially save lives. The lack of money, especially in developing countries, is exacerbated by difficulties with administration, implementation and public awareness. The future of modern earthquake engineering will come to be dominated by new kinds of measuring technologies, new materials developed especially for low-rise, low-cost buildings, simpler and thus lower cost options for retrofitting, cost cutting and raising public awareness. The book covers all the areas involved in this complex issue, from the prevention of total building collapse, through improvement techniques, to legal, financial, taxation and social issues. The contributors have all made valuable contributions in their own particular fields; all of them are or have been closely involved with the issues that can arise in seismic zones in any country. The recent research results published here offer invaluable pointers to practicing engineers and administrators, as well as other scientists whose work involves saving the lives and property of the many millions of people who live and work in hazardous buildings.

This book will appeal to specialist engineers with enquiring minds and, in a broader sense, to all who live in buildings, especially those in a seismically active region. While the continual development of building codes permits the design of new construction to resist earthquake loads more effectively, a major problem is that buildings which may once have conformed to past seismic codes become structurally unacceptable according to today's codes and need upgrading or `retrofitting'. Poor construction methods also result in buildings that do not conform to any codes. Existing `vulnerable' buildings that require strengthening in earthquake-prone countries immensely outnumber all recent construction. The `health' of buildings thus requires assessment and rehabilitation. Seismic assessment ranges from the cataloguing of `danger symptoms' in individual buildings to structural analyses involving finite element procedures and refined statistical analyses incorporating expert systems, stochastic processes and predictions from available databases. Structures have to be rendered fit for earthquakes, and this book goes a long way towards showing why and how, offering the results of cutting-edge research in the area and presenting innovative methods that enable system improvement while the structure remains in use.
