Advanced nonlinear analysis of steel structures subjected to fire and fire following earthquake scenarios

Lecturers: Prof. Nicola Tondini (UNITN/DICAM), Dr. Luca Possidente (UCL), Dr. Patrick Covi (UNITN/DICAM)

Schedule: 13 - 14 June 2024

Description:

The course aims at describing the behaviour of steel structures in case of fire and fire following earthquake (FFE) scenarios. In particular, dynamic analysis and thermomechanical analysis notions will be given through finite element formulation. At the material level, the nonlinear modelling of steel at high temperature and how the constitutive laws is integrated in a finite element framework will be described both for fire and FFE. Moreover, at the element level, large displacement analysis, which is paramount to capture the behaviour of structural systems under fire, will be discussed. More details will be given for the corotational formulation, which decomposes the motion of an element into a rigid body part and a pure deformational part and allows for different nonlinear material descriptions in the local formulation. Several practical examples will be shown to highlight the application of the aforementioned concepts, whilst practical hands-on sessions with computer laboratory exercises are foreseen to implement parts of the tools provided in the course.
