Investigation of the tire waste inclusions on the shear strength parameters od sand

Çağatay, Ahmet. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)

Using tire wastes as lightweight materials in highway embankment construction has many benefits in environmental and geotechnical aspects. Tire waste additions to sand enhance the shear strength of soil for embankment ...
An investigation of inelastic seismic demand

Tufan, Tarık. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)

In Turkish Earthquake Code (TEC), ratio between inelastic and elastic systems with same initial stiffness and damping is defined as spectral displacement ratios (also known as inelastic displacement ratios). The main aim ...
Experimental research on seismic retrofitting of R/C corner beam-column-slab joints upgraded with carbon fiber reinforced polymer (CFRP) sheets

Topcu, İbrahim. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)

An experimental study was conducted on seismically deficient RC corner connections with and without floor slab in order to examine the behavior under seismic action and to develop proper strengthening techniques. Four 2/3 ...
Experimental research on seismic retrofitting of R/C exterior beam-column-slab joints upgraded with carbon fiber reinforced polymer (CFRP) sheets

Gökgöz, Erdal. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)

Under seismic action, the most critical part of R/C structures, which were built in the United States before 1970, is beam-column joints. Common deficiencies of these joints could be summarized as; widely spaced column ...
Artificial neural networks approach for the determination of aquifer parameters

Şahin, A. Ufuk. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)

The determination of the aquifer parameters with sufficient accuracy is an important issue in the application of the mathematical models which have been developed for the groundwater systems. Recently, Artificial Neural ...
Implementation of one and two dimensional linear finite element programs with java language

İşbaşar, Hilmi Aydın. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)

Finite element program codes were generally developed in Fortran but during last decade developers started to seek better programming paradigms in order to handle complexity in finite element software. Since Java language ...
Behavior of reinforced earth structures under earthquakes

Kaya, Turgut. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
