Seminar - Geng Yue - Time dependent behaviour of concrete-filled steel tubes (CFST)

Wednesday 8 October 2008, 1.10 - 1.55 pm
Civil Engineering Lecture Theatre 3

Abstract:

Concrete-filled steel tubes (CFST) are becoming a very popular structural solution for both high-rise building and arch bridge applications because of their high compressive strength as well as efficiency in construction. In this context, an accurate prediction of their time-dependent behavior is required especially in view of modern slender structural solutions which might be more influenced by creep and shrinkage effects. In fact, slender CFST systems are prone to instability problems which may be triggered by the increasing deformations caused by time effects.

This study intends to investigate this behaviour both numerically and experimentally.
