Course Nonlinear Analysis and Design of Concrete Structures

This tutorial introduces practical nonlinear analysis and design workflows for reinforced concrete structures using SOFiSTiK.

Across multiple example models, it explains how nonlinear material behaviour, cracking, stiffness reduction, spring elements, long-term deflection, beam behaviour, wall capacity, and volume elements are handled in finite element analysis. The lessons demonstrate how to define realistic material properties, create suitable load combinations, interpret iterative solver behaviour, and evaluate structural response under serviceability and ultimate limit states.

Special attention is given to cracked concrete modelling, reinforcement effects, and the differences between shell, beam, and solid element approaches for reliable engineering assessment.
