Abstract

A numerical model was established in the non-linear software Safir for unbraced composite frames in fire. The model considers the sequence of construction and load history of the composite frames. In addition, it includes a local model taking semi-rigid composite joints into account. This contribution presents the key features of the model. Furthermore, the model is validated against fire tests and used to study the fire performance of unbraced composite frames. The investigations focused on the influence of base support, geometry of the frames, and location of the fire on the fire performance of unbraced composite frames. This research work is part of the ongoing European project 'Unbraced Composite Structures in Fire'.
