    An effective analytical model based on the hybrid FEM-DRBEM scheme has been developed to study the fluid-structure interaction and earthquake response of arch dam-reservoir systems. Applying the substructure technique, the ...
  • Özden, Şevket. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1998., 1998.)
    The use of flat-plate is becoming popular for medium rise residential and office buildings. The connection between the slab and the column in flat-plate structures is generally the most critical part. The failure of the ...
  • Hanoğlu, Kemal Burak. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering , 2002., 2002.)
    Stiffness and strength contribution of hollow clay tile infills to ductile and non-ductile reinforced concrete frames were evaluated using 1:3 scale specimens tested under quasi-static reversed cyclic seismic loads. Four ...
  • Ertaş, Onur. (Thesis (Ph.D.)-Bogazici University.Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    Post-earthquake field investigations on precast concrete structures revealed that thelevel of damage and the poor performance of the buildings during the 1999 Kocaeli and Düzce Earthquakes in Turkey were closely related ...
  • Altekin, Murat. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    This study reports the static and dynamic analysis of super-elliptical plates ofuniform thickness. There are mainly three distinct boundary conditions (clamped/simplysupportedalong the contour and point supported on the ...
  • Baştopçu, Mehmet Emre. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    This study was carried out in order to investigate the effect of binder composition on fresh and mechanical properties of self-compacting concrete (SCC). Total of eight different concrete mixtures have been produced. All ...
  • Nircan, Ahmet Kutsi. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    This study compares known social choice rules in the context of agent based search and introduces two new variants of stochastic diffusion search algorithm. Performance comparison to match a correct ordering of 36 voting ...
  • Kaya, Erdem. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    The influence of shear deformations in plate bending becomes significant when the ratio of the thickness to span is relatively large. However, the effects of transverse shear strains are neglected normally in classical ...
  • Erkal, Aykut. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    It is natural and common to idealize stress or field problems into finite element models with rigid boundaries remote from the area of interest. However, the degree of accuracy of solutions may be significantly increased, ...
  • Yemez, Kağan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In 80’s and 90’s hollow sections (HS) were mainly used in compression and tension elements of truss systems. Nowadays, architects are more and more using hollow sections in building applications where limited amount of ...
  • Çeribaşı, Seyit. (Thesis (Ph.H..)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this study super elliptical plates are statically and dynamically analyzed. This class of plates includes a wide range of shapes varying from an ellipse to a rectangle. Although studies on the extreme boundaries of the ...
