This article presents the benefits of a nonlinear approach for the analysis of reinforced concrete line elements, intended to determine the unique solution of the mechanical problem — when it exists — by enforcing flexural and axial deformation compatibility at every point along the member.

Inspired by the General Method and fully covered by Eurocode 2, this approach, referred to as the “Integral General Method” or IGM, opens up possibilities for analysing and optimising many common situations, from slender columns to continuous members in combined bending and compression.

The relationship between the structural works package and the special foundations package relies largely on the load transfer schedule which, beyond a simple listing, can play a structuring role in the project’s design and in managing the interface between the packages.

When it specifies the allocation of pile execution tolerances and the mechanical assumptions at the interface, the load transfer schedule helps to clarify the boundary between the packages and to secure the design.
Through a topic that is sometimes not explicitly addressed, this article highlights real geometric, structural, and contractual impacts that are worth documenting from the outset.
