Assessment of racking deformation of rectangular underground structures by centrifuge tests
ÜLGEN, DENİZ; SAĞLAM, SELMAN; Özkan, M. Yener (2015-12-01)
Seismic safety of buried structures has become increasingly important over the past two decades, especially after the destructive earthquakes such as in Kobe, Japan (1995), Kocaeli, Turkey (1999) and Chi-Chi, Taiwan (1999). Some of the embedded structures including pipelines, subways and tunnels collapsed or suffered severe damage in those earthquakes due to inappropriate design. The main difficulty in seismic design is the incorporation of soil-structure interaction effect governed by the relative stiffnes...
Assessment of Acoustical Indicators in Multi-domed Historic Structures by Non-exponential Energy Decay Analysis
GÜL, ZÜHRE SÜ; Çalışkan, Mehmet; Tavukçuoğlu, Ayşe; Xiang, Ning (2018-08-01)
The key concern of this study is to discuss the reliable acoustical metrics for analyzing particular sound fields within monumental multi-domed sacred spaces with an emphasis on multiple sound energy decay formation. The potential of such structures in featuring non-exponential sound energy decay characteristics necessitates new formulation of sound decay indicators in understanding of their sound fields. The early and late energy decay components within non-exponential sound energy decays can have a unique...
Assessment of deformation modulus of weak rock masses from pressuremeter tests and seismic surveys
IŞIK, Nihat Sinan; Doyuran, Vedat; ULUSAY, REŞAT (Springer Science and Business Media LLC, 2008-08-01)
The deformation modulus of intact rock can be determined through standardized laboratory tests for heavily jointed rock masses but this is very difficult, while in situ tests are time-consuming and expensive. In this study, the deformation modulus of selected heavily jointed, sheared and/or blocky, weathered, weak greywacke, andesite and claystone were assessed, based on pressuremeter tests, geo-engineering characterization and seismic surveys. Empirical equations based on GSI and RMR values are proposed to...
Assessment of soil structure earthquake interaction induced soil liquefaction triggering
Unutmaz, Berna; Çetin, Kemal Önder; Department of Civil Engineering (2009)
Although there exist some consensus regarding seismic soil liquefaction assessment of free field soil sites, estimating the liquefaction triggering potential beneath building foundations still stays as a controversial and difficult issue. Assessing liquefaction triggering potential under building foundations requires the estimation of cyclic and static stress state of the soil medium. For the purpose of assessing the effects of the presence of a structure three-dimensional, finite difference-based total str...
Assessment of uncertainties in bed load rate and water surface profile computations
Genç, Gizem; Yanmaz, Ali Melih; Department of Civil Engineering (2023-1-12)
Many processes in water resources engineering are disposed to uncertainty due to the inherent variation of many inputs and parameters in time and place. This study mainly consists of two parts. In the first part, probabilistic variations of bed load rates are examined using Meyer-Peter Müller and Einstein-Brown approaches under the effect of different bed slopes, bed materials, and flow rates in the Miliç Basin. The results of the first part offer an insight into the probabilistic nature of bed resistance. ...
