Regulatory frameworks mandate periodic evaluations to ensure the mechanical integrity of nuclear facilities. Secondary and auxiliary circuits of the primary system, including piping, supports, and equipment, present significant modeling challenges due to their complexity and high component density. High-fidelity modeling of entire piping networks is therefore impractical, and current methodologies typically rely on simplified one-dimensional approaches that treat components independently. The piping system, anchored to the building and the primary circuit, incorporates supports with functional gaps to accommodate loads and displacements, introducing contact nonlinearities. In this context, we propose the development of a design-support tool aimed at enabling efficient simulations within reasonable computational times.
