Assessment of seismic fragility curves for low- and mid-rise reinforced concrete frame buildings using Duzce field database

This paper focuses on the generation of fragility curves for low-rise and mid-rise reinforced concrete frame buildings, which constitute approximately 75% of the total building stock in Turkey and which are generally occupied for residential purposes. These buildings, which suffered extensive damage after recent earthquakes, are not designed according to the current code regulations and the supervision in the construction phase is not adequate. Hence the buildings possess many deficiencies like irregularities in plan and elevation, weak column-strong beam connections, poor concrete quality, inadequate detailing of reinforcement in hinging zones, etc. In this study, the test bed, which represents the characteristics of the aforementioned frame buildings, is selected as the Duzce field database. The influence of ground motion characteristics, structural input parameters, sampling techniques, sample size, type of hysteresis model and limit state definitions on the response statistics is investigated and fragility curves for low- and mid-rise reinforced concrete structures in Turkey are proposed as an end product.


A comparative study on earthquake resistance of reinforced concrete and masonry residential buildings in small-scale cities of Turkey
Er Akan, Aslı; Ünay, Ali İhsan; Department of Building Science in Architecture (2008)
Today the vast majority of urban population in Turkey is living in multi-story apartment blocks constructed of reinforced concrete due to the fact that in the late 19th century concrete and steel took the place of traditional materials such as masonry. However, it cannot be denied that masonry is still a crucial material for load bearing walls, internal walls and cladding of buildings. In addition to this masonry construction system has many advantages. From the architectural point of view, it provides flex...
Fragility-based assessment of typical mid-rise and low-rise RC buildings in Turkey
Erberik, Murat Altuğ (2008-05-01)
This paper focuses on the seismic fragility assessment of typical low-rise and mid-rise reinforced concrete (RC) buildings in Turkey by considering Duzce Damage database, which was compiled after the two devastating earthquakes in 1999 that affected the Marmara region. A set of fragility curves is developed by making use of the building characteristics in the database. The generated fragility curve set is referred as "reference" since it forms the basis of a parametric study. Then the influence of sampling ...
A comparative structural and architectural analysis of earthquake resistant design principles applied in reinforced concrete residential buildings in Turkey
Özmen, Cengiz; Ünay, Ali İhsan; Department of Building Science in Architecture (2008)
The aim of this thesis is to demonstrate that it is possible to design earthquake resistant residential structures without significant compromises in the spatial quality and economic viability of the building. The specific type of structural system that this thesis focuses on is the reinforced concrete skeleton system. The parametric examples and key studies that are used in this research are chosen among applied projects in the city of Bolu. This city is chosen due to its location on the North Anatolian Fa...
Detailed evaluation of an existing reinforced concrete building damaged under its own weight
Bayraktar, Atilla; Yakut, Ahmet; Department of Civil Engineering (2011)
A significant part of the Turkey’s building inventory consists of reinforced concrete frame structures. In addition to that a big part of the existing building inventory in Turkey shows insufficiency in seismic performance damage or failure of structures under their own loads has also been observed. The failure of Zümrüt Apartment building that occurred in 2004 in Konya and resulted in the death of 92 people brings the necessity of researches on robustness and reserve capacities of the buildings under gravi...
Seismic behavior assessment of low-rise reinforced concrete structural walls using quasi-static reversed cyclic loading protocol
Ezzatfar, Pourang; Canbay, Erdem; Özcebe, Güney; Department of Civil Engineering (2016)
The reinforced concrete shear walls of low- to mid-rise residential buildings, having height to length ratio ranging from 1 to 3, are more of a concern in research studies in recent years. Since the failure mode of these walls depends on the interaction between shear and flexural action, predicting the failure mode of this type of shear walls is not straight forward. While seismic behavior of highrise walls (i.e. aspect ratio greater than about 3) is almost known and theoretical assumptions matches well wit...
