Finite Element Method of Corner Joints in Steel-Framed Structures under Fire Conditions

Abstract:

An improved component-based model has been developed which includes nonductile(brittle) components (bolts and welds) into a connection model with a reasonable assumption of their failure displacements, based on experimental tests.This model was created for a flexible end-plate connection, using the ABAQUS finite element code, in order to investigate its resistance and ductility at ambient and elevated temperatures. In the subsequent analyses, steel beams and columns are going to be simulated as finite shell/beam elements and the connection behaviour is to be represented by the simplified models. This sub-frame model will also be used for parametric studies to investigate restrained beam behaviour under fire attacks with particular emphasis on the role of the connections.
