Preliminary seismic vulnerability assessment of existing reinforced concrete buildings in Turkey Part II: Inclusion of site characteristics

The vulnerability assessment method, described in the companion paper [1], relies on a damage score, which is compared with an appropriate cutoff value to identify the buildings as "safe", "unsafe" or "intermediate". The cutoff values are considered to be valid for damaging earthquakes and regions similar to Duzce, where the data was gathered. To generalize the procedure, the variability of ground motion with respect to soil properties and the distance to source needs to be incorporated. This was done by modifying the cutoff values based on the above factors. Sites are classified according to the Turkish Seismic Code's [2] definitions based on the shear wave velocity. Various attenuation relations are used to account for the variation of the ground motion with distance and the soil type.
Workshop on Seismic Assessment and Rehabilitation of Existing Buildings


Development of internet based seismic vulnerability assessment tools
Türer, Ahmet (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 resid...
An evaluation of seismic hazard and potential damage in Gaziantep, Turkey using site specific models for sources, velocity structure and building stock
Karimzadeh, Shaghayegh; Arslan Kelam, Arzu; Yousefibavil, Karim; Akgün, Haluk; Askan Gündoğan, Ayşegül; KOÇKAR, MUSTAFA KEREM; Erberik, Murat Altuğ; Ciftci, Hacer; Pekcan, Onur (2022-03-01)
Assessment of potential seismic risk and losses in urban environments is necessary for several purposes ranging from risk mitigation to city and regional planning. It is well known that loss estimation should be performed within an interdisciplinary setting involving earth sciences and engineering. Field experience from recent events worldwide shows that the spatial variability of seismic damage is due to the combined effects of earthquake source properties, local site conditions and structural characterist...
Modelling effects of insufficient lap splices on a deficient reinforced concrete frame
Lin, Wesley Wei -Chih; Sucuoğlu, Haluk; Binici, Barış; Department of Earthquake Engineering and Engineering Seismology (2013)
In order to reduce seismic risk in vulnerable buildings, buildings identified to be at risk should be assessed and strengthened. Performance evaluation of deficient buildings has become a major concern due to devastating earthquakes in the past. In order to justify new provisions in design and assessment codes, experiments and analyses are inherently necessary. In this thesis study, investigations into the behaviour of two deficient reinforced concrete frames built at Middle East Technical University’s Str...
An Experimental Study on Impact of Risk Data Visualization onRisk Evaluations
Dikmen Toker, İrem; Eken, Görkem (null; 2018-11-18)
Risk assessment is a systematic process to characterize and evaluate risk, with the available knowledge. Thus, its success depends significantly on the "availability of knowledge" during the assessment process. The knowledge elicitation from experts, the structure of the risk database and information visualization that may help sense-making from previous projects are critical factors that can improve risk assessment process. Risk assessment is usually carried out at the start of a project and updated during...
Characterization of laser scanners for detecting cracks for post-earthquake damage inspection
Anil, Engin Burak; Akinci, Burcu; Garrett, James H.; Kurç, Özgür (2013-01-01)
Objective, accurate, and fast assessment of damage to buildings after an earthquake is crucial for timely remediation of material losses and safety of occupants of buildings. Laser scanners are promising sensors for collecting geometrical data regarding the damaged states of buildings, as they are able to provide high coverage and accuracy at long ranges. Yet, we have limited knowledge on the performance of laser scanners for detecting earthquake damage, and requirements of such data collection. This paper ...
