Numerical Study on Web Crippling of Aluminium Lipped Channel Sections
Aluminium alloys are nowadays used abundantly in the building construction due to its advantages such as lightness, resistance to corrosion, ease of manufacture and more strength to weight ratio. Aluminium sections are used in roof structures, curtain wall and other structural applications. Thin-walled structural members are extremely vulnerable to buckling instabilities, including web crippling, which is one of the failure that occur in Aluminium sections under transverse concentrated loads or reactions. Aluminium members are highly prone to this kind of failure because of their low elastic modulus. This paper presents the details of a numerical investigation conducted on the web crippling of fastened Aluminium lipped channel (ALC) sections. Furthermore, the effect of connection contacts and the effect of various frictional coefficients on the web crippling behaviour are also included in this investigation. From the study it is observed that modelling of connection contact plays a significant role in the numerical study of web crippling behaviour. At the same time it is realised that the change in frictional coefficients does not considerably influence the force displacement relationship.
