Slip lineation data developed on the cooling joints of a Pliocene ignirnbrite sheet are measuremed in the vicinity kuyu Fault to determine the state and the orientation of stresses in the region. The data are taken along three different survey lines in order to improve the reliability of the data as well as to observe the change in the nature of reactivation as a of distance to the main fault. The analysis involved in the evaluation of the data to find the stress are graphical solutions, namely, the and P-T dihedra methods. The solutions of the methods have shown that a, is sub-vertical. and and are sub-horizontal There is no preferred orientation of reactivation as displayed by the development of slickensided surfaces in all directions. terns of the diagrams are consistent in all survey lines indicating that the distance to the main fault is not significant. there is not any direct control of the main fault on the development of the reactivation of preexisting cooling joints, but rather the fault is a result of the present state of stress which reflects a typical example of radial stress field.

An investigation of liquefaction effects on piers and piles of segmental precast balanced cantilever bridges Gündüz, Özer; Caner, Alp; Department of Earthquake Studies (2019) In this thesis, the seismic behavior of a typical segmental precast balanced cantilever bridge over liquefiable soils is investigated. Liquefaction is a phenomenon that is triggered by large movements of the sand layer during earthquakes and cause damage to structures. The subject is still under investigation, approaches for liquefaction induced lateral spreading calculations can be found in the literature. Inertial and kinematic effects of the lateral spreading were studied with a total of four different a...
EFFECT OF SURFACE ROUGHNESS IN PARALLEL-PLATE MICROCHANNELS ON HEAT TRANSFER Turgay, M. B.; Güvenç Yazıcıoğlu, Almıla (Informa UK Limited, 2009-01-01) In this study, the effect of surface roughness on convective heat transfer in two-dimensional parallel plate microchannels is analyzed numerically for steady-state, single-phase, developing, and laminar air flow in the slip flow regime. Slip velocity and temperature jump at wall boundaries are imposed to observe the rarefaction effect. The effect of triangular roughness elements on Nusselt number are compared to cases with smooth surfaces. The results indicate that increasing surface roughness reduces heat ...
Influence of the shear wall area to floor area ratio on the seismic performance of existing reinforced concrete buildings Günel, Ahmet Orhun; Burak Bakır, Burcu; Department of Civil Engineering (2013) An analytical study is performed to evaluate the influence of shear wall area to floor area ratio on the behavior of existing mid-rise reinforced concrete buildings under earthquake loading. The seismic performance of five existing school buildings with shear wall ratios between 0.00% and 2.50% in both longitudinal and transverse directions and their strengthened counterparts are evaluated. Based on the structural properties of the existing buildings, additional buildings with varying shear wall ratios are ...
Implementation of coupled thermal and structural analysis methods for reinforced concrete structures Albostan, Utku; Kurç, Özgür; Department of Civil Engineering (2013) Temperature gradient causes volume change (elongation/shortening) in concrete structures. If the movement of the structure is restrained, significant stresses may occur on the structure. These stresses may be so significant that they can cause considerable cracking at structural components of large concrete structures. Thus, during the design of a concrete structure, the actual temperature gradient in the structure should be obtained in order to compute the stress distribution on the structure due to therma...
Kinematic and structural development of the Çankiri Basin Central Anatolia Turkey a paleostress inversion study Kaymakcı, Nuretdin; Paul M, Vandijk (2003-03-01) Three different deformation phases have been recognized in the southern part of the Cankin Basin from (1) the major structures and (2) through using paleostress inversion techniques for fault slip data. The deformation phases recognized from the paleostress data are correlated with those recognized from the major structures and dated accordingly. The first phase occurred in the Late Paleocene to pre-Burdigalian and is characterized by an oblique sigma(2) and NNE-SSW to NE-SW trending subhorizontal sigma(1) ...
