The flexibility of steel hollow tubular sections subjected to thermal and mechanical loads
Advisor(s)
Abstract(s)
Numerical analysis of hollow tubular sections is used as a starting tool to
establish the reliability assessment of these elements when mechanically or
thermally loaded. To quantify the material deformation behaviour of these
elements resulting from ground motion, crack propagation, effects from high
temperatures, theoretical and experiments analyses can be used for testing a
service reliable guarantee. Structural hollow sections have excellent static
properties, not only with regard to buckling and torsion, but also in the overall
design of members. They can offer economic advantages compared to open
sections. It is possible to change the strength by varying the wall thickness or
filling the section with other material without changing the external geometry.
Flexibility is an important parameter in hollow tubular systems when subjected
to thermal or mechanical loads. This work presents a numerical analysis
technique based on the finite element method for thermal and mechanical nonlinear
behaviour. Temperature field will be calculated according to non-steady
conditions when submitted to standard ISO834 and non-linear material
properties foreseen in Eurocode standards (EC1 and EC3). This work will
present a complete study of the flexibility analysis for a wide range of pipe
dimensions, and the obtained results are then compared with design rules.
