Abstract: Loads applied at the ground surface may have a significant effect on culverts and buried pipelines. A semi‐analytic procedure is developed to estimate the response of buried tubes to surface loads. The procedure can be ...

Abstract: A parametric study of elliptical tubes deeply buried in uniform elastic ground is reported. The static tube response is determined using both analytical and numerical methods for a range of tube geometries and ground and ...

Abstract: Theoretical models and experimental data for buried tube buckling are reviewed, and linear buckling solutions based on the elastic continuum model for the ground are selected as being most suitable for the design of buried ...

Abstract: A simplified analytical postbuckling theory has been developed for long, circular, elastically supported tubes. The solution is an extension of linear theories which have previously been developed. Although the analysis ...

Abstract: The harmonic response of an infinitely long thick elastic tube is considered. Exact displacement and stress fields for steady‐state vibration are developed. Stiffness equations are derived, relating the internal and external ...

Abstract: The dynamic steady‐state response of long elastic and viscoelastic tubes to patch loadings is considered. Tube response to an isolated load set is assembled from harmonic behavior using Fourier transforms, and response to ...

Abstract: Horizontal directional drilling (HDD) is now widely used for pipe installation by the trenchless industry. Horizontal borehole stability under excessive mud pressure can be a concern during the drilling processes. The Delft ...

Abstract: Polymer sewer pipe load carrying ability when deflected to 20% pipe deformation under parallel plate loading is used in industry as an index of pipe quality. New developments in limit states design also require the assessment ...
