Abstract
This paper presents a macroelement force-resultant model (termed as UWAPIPE) to numerically simulate pipe-soil interaction. It utilizes bounding surface theory as its framework to describe the combined vertical and horizontal load-displacement behavior of a pipe in calcareous sands. By numerically attaching numerous force-resultant elements to structural nodes and by taking a balanced approach between structural and foundation sophistication, the analysis of long pipeline becomes computationally feasible. A method based on three dimensional beam theory and the Finite Element (EE) displacement concept to implement the UWAPIPE into FE program is described in this paper. It assembles the struct..
