Earthquakes near major cities may cause big social and economic impacts. Damages to port facilities may cripple the economy. The past twenty years' experience has proven the high vulnerability of the port facilities. This fact, along with the economic importance of port structures, indicates the need for better seismic design approaches for berth structures and cargo handling facilities. In the recent decades, there have been many incidences of failure of gravity type quay walls. These failures have stimulated research interest in the development of performance-based design methods. In this paper, two different hunchbacked block type quay walls with different back face shape were studied. A series of 1-g shaking tank tests was performed using a 1/10 scaled block type quay wall with gravel backfill materials on firm non-liquefiable sea bed conditions subjected to different harmonic loads. The shaking tank tests provided insight into the wall displacements and the total dynamic pressures by analyzing pressure components at the contact surface between the saturated gravel backfill soil and the wall. It is concluded that the back-face shape of the walls is an important factor and the larger positive slope of the wall improves the overall seismic stability.

Seismic vulnerabilities and risks for urban mitigation planning in Turkey
Saner, Tugce Sonmez (2015-09-01)
Chronic seismic hazards and resulting secondary impacts as natural conditions of the country, and the loss of robust building and prudent settlement practices as aggravated by rapid population growth make cities the most vulnerable geographical and social entities in Turkey. For the development of risk reduction policies, an essential step is to prioritize settlements according to their vulnerability levels. This could be determined by hazard probabilities and attributes of the building stock of each settle...
Seismic performance of masonry buildings subjected to synthetic ground motions
Koç, Ahmet Bahadır; Erberik, Murat Altuğ; Department of Civil Engineering (2019)
Over the centuries, strong seismic activities have occurred with uncertain frequencies in the world which caused earthquake-prone regions to be severely influenced in terms of structural damage and economic losses. Therefore, seismic assessment approaches have been developed to minimize the vulnerability of structures, to carry out pre-earthquake mitigation planning and to mitigate economic losses. This study mainly focuses on the performance estimation of unreinforced masonry (URM) structures using synthet...
Comparative study of base isolated systems
Türkmen, Fatih; Akyüz, Uğurhan; Department of Civil Engineering (2002)
This thesis is mainly concerned with providing brief knowledge about the effects of earthquakes on buildings and their response to earthquake forces. Principles of advanced passive earthquake resistant design techniques are also presented. Next, the use of the most common passive earthquake resistant design technique; i.e., base isolation is described, with its historical background, main principles and usage in the world. In order to evaluate the effectiveness of base isolation, and the performance of base...
Seismic fragilities for non-ductile reinforced concrete frames - Role of aleatoric and epistemic uncertainties
Çelik, Ozan Cem (2010-01-01)
Seismic fragilities are essential to earthquake loss estimation and performance-based earthquake engineering in regions of high seismicity. Construction practices for frames in regions of moderate seismicity are quite different, and such frames have received less attention in the literature. Fragilities for performance levels identified in recent seismic regulations are developed herein for reinforced concrete frames designed for gravity load in low-seismic regions using probabilistic non-linear finite elem...
Estimation of dynamic soil properties and soil amplification ratios with alternative techniques
Şişman, Fatma Nurten; Askan Gündoğan, Ayşegül; Özacar, Atilla Arda; Department of Earthquake Studies (2013)
Earthquakes are among the most destructive natural disasters affecting urban populations. Structural damage caused by the earthquakes varies depending not only on the seismic source and propagation properties but also on the soil properties. The amplitude and frequency content of seismic shear waves reaching the earth’s surface is dependent on local soil conditions. It is well known that the soft sediments on top of hard bedrock can greatly amplify the ground motion and cause severe structural damage. When ...
