文摘

Behaviour and strength of stiffened lipped channel columns experiencing L-D interaction Two different types of L-D mode interaction identified, investigated and characterised Development and calibration of DSM-based design approaches against L-D interactive failures Numerical and experimental failure loads used to assess the merits of the DSM design approaches Reliability assessment of the DSM design approaches developed to predict the column failure loads
