Development of internet based seismic vulnerability assessment tools

2005-06-01
Seismic assessment methods are commonly divided into three phases: a) quick assessment b) detailed analysis and c) advanced methods. The dilemma between the large number of buildings to be assessed and low number of technical personnel and funding to assess buildings makes large cities wait on halt. Internet Earthquake Project (InEP) initiated as a Middle East Technical University BAP project in full conjunction with NATO-SfP977231 project, targets internet users to process the buildings in which they reside to carry out the time consuming process of collecting building data. Furthermore, the internet site has a target to disseminate knowledge about basic civil engineering principles and build earthquake vulnerability awareness. Projection of about 5 million internet users in Turkey by the year 2005 builds a good potential for processing the existing building stock. The Internet Earthquake Project's web site is currently fully functional except for ongoing studies of improvement. "Simplistic" and "Complicated" evaluation options are expected to fulfill the beginner and advanced level internet user's level of competency. Concerns about the reliability of entered data and legal (reliability) issues are still under discussion. This study can be viewed as a "first attempt" to carry seismic assessment of existing buildings to the internet, rather than as a final product.

Development of Fragility Curves for Single-Column RC Italian Bridges Using Nonlinear Static Analysis
Perdomo, Camilo; Monteiro, Ricardo; Sucuoğlu, Haluk (Informa UK Limited, 2020-05-07)
The main objective of this study is to assess the accuracy and suitability of Nonlinear Static Procedures (NSPs) in the development of analytical damage fragility curves for seismic risk assessment of large portfolios of Reinforced Concrete (RC) bridges. Seven NSP approaches, from widely used single-mode conventional pushover-based approaches to the more rigorous multi-mode conventional or adaptive pushover-based procedures are implemented. By systematically comparing fragility curve estimations in terms of...
Technical Note: Practical Challenges Facing the Selection of Conditional Spectrum-Compatible Accelerograms
Ay, Bekir Özer; Sullivan, Timothy John (Informa UK Limited, 2017-01-01)
There are various possibilities for the selection and scaling of ground motions for advanced seismic assessment of buildings using nonlinear response-history analyses. As part of an on-going project looking at building-specific loss assessment in Italy, this article highlights a number of challenges currently facing the use of conditional spectra for ground motion selection in practice, essentially related to the limited amount of seismic hazard information that is publicly available. To illustrate the poin...
Use of simulated ground motions for the evaluation of energy response of simple structural systems
Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ (Elsevier BV, 2019-08-01)
The literature on energy-based seismic design and assessment methodologies of structural systems mostly relies on real ground motion datasets. However, certain bias exists due to lack of homogeneity in available ground motion datasets. In this study, a large set of ground motions is simulated. Next, the effects of various parameters on seismic behavior of SDOF systems in terms of energy are studied using nonlinear time history analyses. The stochastic finite-fault simulations are performed on the western pa...
An approach for landslide risk assesment by using geographic information systems (gis) and remote sensing (rs)
Erener, Arzu; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2009)
This study aims to develop a Geographic Information Systems (GIS) and Remote Sensing (RS) Based systematic quantitative landslide risk assessment methodology for regional and local scales. Each component of risk, i.e., hazard assessment, vulnerability, and consequence analysis, is quantitatively assessed for both scales. The developed landslide risk assessment methodology is tested at Kumluca watershed, which covers an area of 330 km2, in Bartın province of the Western Black Sea Region, Turkey. GIS and RS t...
Investigation of seismic isolation efficiency for building structures
Özdemir, Seda; Yakut, Ahmet; Ay, Bekir Özer; Department of Earthquake Studies (2016)
The main goal of this study is to assess the efficacy of seismic isolation for building type of structures with different structural systems, namely, dual systems and moment frame systems having also different number of floors. Specific to this study, the main parameters employed for efficacy assessment will be the interstorey drift ratio and floor acceleration since both structural and non-structural damage to be occured in a system are directly related to these two parameters. To assess the variations in inter...
