Moment distribution is a method by which statically indeterminate structures are analysed elastically. It’s based on the relative stiffness of elements, and shifts bending moments from one section of the structure to another until they become balanced. Once this balance has been achieved, forces and bending moments are modelled. Updated in October 2016.
Once the concept and scheme design has been determined, initial sizing of elements commences. This note shows how to size elements, prior to detailed design. This process allows the engineer to gain an appreciation of structural form.
This note explains the various methods adopted to ensure lateral stability and robustness in structures.
