  3. Abstract:
  4. The underground and buried oil and gas pipelines are continuously in contact with earthen soils on the outer surface and compressible fluids on the inner surface. Most these earthen soils can be appropriately represented by a model named Pasternak. Similarly, undersea oil and gas pipelines and tubes of heat exchangers remain in contact with fluids on both sides and also rockets and missiles filled with solid and liquid fuels and shallow shells supported on soft and light filaments in space vehicles, boilers and storage tanks on floor grid work in ships can also be considered as thin circular cylindrical shells on a Pasternak foundation. The basic aim of the presented study is investigation and formulation the effect of influences of foundation parameters and the orientation of wire rope cord composite materials on the vibration behaviour of a cord composite simply supported cylindrical shell. Governing dynamic equilibrium equations and frequency equation are developed and the eigen frequencies have been calculated too
