  • Seismic retrofitting of RC beam-column joints using composite materials 
    Kaya, Osman. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    Many of the existing reinforced concrete structures built prior to 1999 have deficient design details due to their non-seismic design or construction flaws. These structures are at risk of collapse under severe earthquakes. ...
  • A method of evaluation of relationship between the safety management and overall safety performance in construction industry 
    Metinsoy, Tamer. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    Safety is crucial in construction industry. From beginning to end, the construction process is complex and characterized by a number of uncertainties and a high fatality rate. But despite its high fatality rate constructions ...
  • Internal erosion of geosynthetic clay liners under high hydraulic heads 
    Özhan, Hakkı Oral. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
    A geosynthetic clay liner is a material composed of a thin layer of bentonite sandwiched between two layers of geotextiles. Low hydraulic conductivity of the bentonite in GCLs makes them more impermeable. Geosynthetic clay ...
  • Negotiating with qualitative preferences: methods for generating bids effectively 
    Aydoğan, Reyhan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
