The twisting of elements within structures due to eccentric loading is best avoided. Such actions develop torsion forces - which the elements were not designed to withstand. This note shows structural engineers how to avoid problems that can lead to significant remedial works and/or failures.
This note is split into two sections; the ﬁrst contains information a designer of steel elements provides, while the second contains information a fabricator creates in order to manufacture and construct the steel structure. While one feeds into the other, the level of detail each set of information provides is very different, due primarily to the end result. One is informing the manufacture of the steelwork, while the other focuses on its installation.
This note explains the various methods adopted to ensure lateral stability and robustness in structures.
