A transport matrix algorithm for the static analysis of circular helicoidal bars

Abstract EN

This paper presents a numerical procedure which has been devised to perform the static analysis of irregular helicoidally bars.

Based upon derived transfer functions, the equations of static equilibrium and deformations are formulated for a representative helicoids.

These equations are then used to determine the state of stress and / or deformation at any section along the bar.

In addition to its usefulness for the analysis of freely standing helicoids, and due to its systematic development, the method is particularly useful to account for the interaction between helicoidally bars and any other aggregate of structural members.
