The risk of damage during the construction phase of a coastal structure was investigated by utilizing Level II and III reliability methods. Structural risks were incorporated in the planning phase of coastal projects by utilizing a practical risk management approach implemented in the Mezitli (Icel) Yacht Harbor project in Turkey. By specifying the exceedance probability of damage level at the design stage, the delay times of construction activities due to damage were obtained at the project-planning phase, which enabled the estimation of the project completion time. It is found that structural risk of damage in the construction period can be an important factor to be considered in the reliability-based project management. because coastal projects involve considerable damage risk during the construction phase. The application of Monte Carlo simulations (Level III), which is generally performed within a few minutes of CPU time in fast computers, has the advantage of robustness when compared with the second-order methods such as the Hasofer-Lind method, provided that the probability distribution of random variables and their correlation are described with an acceptable accuracy, which should be obtained from data accumulated over a sufficient number of years. In this study, by specifying the exceedance probability of "no damage level" at the design stage, the probability of construction completion times were estimated at the planning phase for the case study of Mezitli Yacht Harbor, where the probability distributions of random variables were obtained from the governmental archives.

Seismic vulnerability, behavior and design of tunnel form building structures Balkaya, C; Kalkan, E (Elsevier BV, 2004-12-01) Multi-story reinforced concrete tunnel form buildings are one of the common structural types in regions prone to high seismic risk due to the buildings inherent earthquake resistance and ease of construction. Despite their good performance during earthquakes in 1999 in Turkey, and abundance of such structures scattered worldwide, current seismic codes and design provisions provide insufficient guidelines for their seismic design. As a compensatory measure, a series of modal and nonlinear static analyses are...
Seismic behavior and improvement of autoclaved aerated concrete infill walls Binici, Barış; Canbay, Erdem; Uzgan, Ugur; Eryurtlu, Zafer; Bulbul, Koray; Yakut, Ahmet (Elsevier BV, 2019-08-15) Performance of infill walls in reinforced concrete (RC) frames is generally questionable under the combined action of in-plane and out-of-plane seismic demands. Despite the vast number of tests investigating the behavior of brick masonry infill walls in RC frames, past research is limited for infill walls made of Autoclaved Aerated Concrete (AAC) blocks. In the first part of the study, six single-bay single-story half-scaled RC frames were tested under the action of in-plane cyclic displacement excursions a...
Fragility based assessment of lowrise and midrise reinforced concrete frame buildings in Turkey Ay, Bekir Özer; Erberik, Murat Altuğ; Department of Civil Engineering (2006) In this study, structural vulnerability of reinforced concrete frame structures by considering the countryspecific characteristics is investigated to manage the earthquake risk and to develop strategies for disaster mitigation. Lowrise and midrise reinforced concrete structures, which constitute approximately 75% of the total building stock in Turkey, are focused in this fragilitybased assessment. The seismic design of 3, 5, 7 and 9story reinforced concrete frame structures are carried out according to the ...
Re-examination of damage distribution in Adapazari: Geotechnical considerations Bakır, Bahadır Sadık; Yakut, Ahmet (Elsevier BV, 2005-06-01) The role of ground conditions in damage distribution patterns of buildings in the city of Adapazari during the 17 August 1999 Izmit (Kocaeli) earthquake (M-w 7.4) is investigated. Damage was concentrated in the central districts of the city over the alluvial basin where four to seven-story reinforced concrete buildings were most adversely affected. Two distinct and mutually exclusive modes of building damage were observed on the alluvium: structural system failures due to strong ground shaking, and foundati...
Investigation of strenghthening techniques using pseudo-dynamic testing Kurt, Efe Gökçe; Özcebe, Güney; Department of Civil Engineering (2010) Pseudo-dynamic testing was employed to observe the seismic performance of three different retrofit methods on two story three bay reinforced concrete frame structures. The three test frames have hollow clay tile (HCT) infills in the central bay. All of the test frames represent the seismic deficiencies of the Turkish construction practice such as use of plain reinforcing bars, low strength concrete and insufficient confining steel. Two non-invasive and occupant friendly retrofit schemes suggested in the Tur...
