Book Description
A study of buildings in Shelby County, Tennessee and Tipton County, Tennessee was conducted using a sidewalk survey procedure developed by the Federal Emergency Management Agency (FEMA), known as a Rapid Visual Survey (RVS). Its purpose is to identify buildings that are potentially at risk to a seismic event. A database of these buildings was generated from the data gathered in the RVS procedure. A loss estimation program developed by FEMA, known as HAZUS-MH MR3, was used to perform a more detailed analysis on the structures utilizing user defined ground motion maps. A rank of the structures was developed based upon the RVS procedure and the HAZUS output.FEMA developed HAZUS-MH MR3 which estimates structural and non-structural losses for a variety of hazards. In this study, three earthquake scenarios were analyzed: a magnitude 6.5 earthquake based upon site-specific ground motion maps, a magnitude 7.7 earthquake based upon site-specific ground motion maps, and a magnitude 7.7 earthquake based upon ground motion maps provided by the United States Geological Survey (USGS). All of these ground motion maps simulate a desired earthquake scenario to perform a loss estimate of the buildings; however, the site-specific, user-supplied maps have many more unique ground motion parameters than the USGS maps. HAZUS provides loss estimates by computing damage state probabilities for each building. One objective of this research is to develop a prioritization of the structures based upon building performance from the HAZUS loss estimate and the RVS procedure, which has a possible application to air emergency planners in selecting suitable locations to be used as mass population shelters in the case of a seismic event. The second objective of this research is to assess how well the RVS procedure performs in identifying structures which may be seismically at risk as compared to the HAZUS output by performing a statistical analysis and hypothesis testing on the data. The results of this objective can be utilized in determining if the RVS procedure is suitable for the seismic evaluation of structures or it a more detailed, site specific analysis should be performed using hazard software like HAZUS. The third objective is to investigate how the building type and the construction time period of structures affect the results of HAZUS and the RVS using statistical analysis. The results of the third objective can help in determining which construction materials perform better in a seismic event, which can have structural design applications for regions of high seismicity. The last objective is to examine how the effects of site specific ground motion maps compare with those provided by the USGS, in HAZUS loss estimates. .

Book Description
Empirical Seismic Vulnerability and Resilience Assessment of Building Clusters analyzes the seismic vulnerability analysis of four types of structures and studies and discusses the evaluation of structural damage using risk analysis and shaking table test methods. It does not consider the contribution of typical empirical structural seismic damage data to structural vulnerability assessment and prediction. It is recognized that the impact of earthquakes on large-scale areas is extensive, not only on a building but also on a group of buildings. The book is based on the research background of typical seismic damage characteristics of 11 types of engineering structures. It analyzes the characteristics of the vulnerability of various structures and provides measures and methods to improve the vulnerability of various structures. Combined with probability risk, reliability, machine learning, and other means, vulnerability prediction and evaluation models are established, respectively, and the rationality of the models is verified by hundreds of onsite earthquake damage survey data.

Book Description
The main objective of this study is to develop a methodology to assess seismic vulnerability of concrete structures and to estimate direct losses related to structural damage due to future seismic events. This dissertation contains several important components including development of more detailed demand models to enhance accuracy of fragility relationships and development of a damage assessment framework to account for uncertainties. This study focuses on concrete structures in the Mid-America region where a substantial seismic risk exists with potential high intensity earthquakes in this geographic region. The most common types of concrete structures in this area are identified based on the building inventory data and reinforced concrete (RC) frame buildings and tilt-up concrete buildings are selected as case study buildings for further analysis. Using synthetic ground motion records, the structural behavior of the representative case study buildings is analyzed through nonlinear time history analyses. The seismic performance of the case study buildings is evaluated to describe the structural behavior under ground motions. Using more detailed demand models and the corresponding capacity limits, analytical fragility curves are developed based on appropriate failure mechanisms for different structural parameters including different RC frame building heights and different aspect ratios for tilt-up concrete structures. A probabilistic methodology is used to estimate the seismic vulnerability of the case study buildings reflecting the uncertainties in the structural demand and capacity, analytical modeling, and the information used for structural loss estimation. To estimate structural losses, a set of damage states and the corresponding probabilistic framework to map the fragility and the damage state are proposed. Finally, scenario-based assessments are conducted to demonstrate the proposed methodology. Results show that the proposed methodology is successful to evaluate seismic vulnerability of concrete structures and effective in quantifying the uncertainties in the loss estimation process.

Book Description
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.
