    • Buckling design of confined steel cylinders under external pressure 

      Vasilikis, D.; Karamanos, S. A. (2010)
      Thin-walled steel cylinders surrounded by an elastic medium, when subjected to uniform external pressure may buckle. In the present paper, using a two dimensional model with nonlinear finite elements, which accounts for ...

    • Buckling of clad pipes under bending and external pressure 

      Vasilikis, D.; Karamanos, S. A. (2011)
      The present paper concerns the structural behaviour of clad pipes. This is a double wall pipe, composed by two pipes that are in contact through an appropriate manufacturing procedure; a thick-walled carbon steel "outer ...

    • Buckling of thin-walled long steel cylinders under bending 

      Houliara, S.; Karamanos, S. A. (2010)
      The present paper investigates structural response and buckling of long unstiffened thin-walled cylindrical steel shells, subjected to bending moments, with particular emphasis on their stability design. The cylinder ...

    • Buckling of unconfined and confined thin-walled steel cylinders under external pressure 

      Vasilikis, D.; Karamanos, S. A. (2008)
      The present paper investigates the structural stability of thin-walled steel cylinders subjected to uniform external pressure. A brief discussion of unconfined steel cylinder buckling is presented first. Subsequently, ...

    • Buried steel pipelines crossing strike-slip faults 

      Vazouras, P.; Karamanos, S. A.; Dakoulas, P. (2012)
      The paper examines the behaviour of buried steel pipelines crossing active strike-slip faults. The vertical fault plane is crossed by the pipeline at an angle ranging between zero and 45 degrees, causing significant plastic ...

    • Reliability analysis of dynamical systems 

      Jensen H., Papadimitriou C. (2019)
      The use of reduced-order models in the context of reliability analysis of dynamical systems under stochastic excitation is explored in this chapter. A stochastic excitation model based on a point-source model is introduced, ...

    • Seismic design of buried steel water pipelines 

      Karamanos, S. A.; Keil, B.; Card, R. J. (2014)
      The present paper provides an overview of available tools and provisions for the structural analysis and design of buried welded (continuous) steel water pipelines in seismic areas, subjected to earthquake action. Both ...

    • Seismic response of unanchored liquid storage tanks 

      Vathi, M.; Karamanos, S. A. (2012)
      Unanchored liquid storage tanks under strong earthquake loading tend to uplift. In the present study, the effects of base uplifting on the seismic response of unanchored tanks are presented with emphasis on elephant's foot ...

    • Wrinkling of lined pipes under bending 

      Vasilikis, D.; Karamanos, S. A. (2012)
      The present study is motivated by the use of lined pipes in energy pipeline applications (oil, gas, etc.) where a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on ...

    • Wrinkling of lined steel pipes under bending 

      Vasilikis, D.; Karamanos, S. A. (2013)
      Lined pipes are used in energy pipeline applications (oil, gas, etc.); a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on wrinkling of lined pipes (sometimes also ...
