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.
This note is a good practice guide for analysing and designing structures. It explains how structures are given form, modelled, analysed and designed. Mention is made of the need to rationalise the analysis process, but not at the expense of an economic design.
This note concerns the assessment of loads that apply to retaining structures, typically generated from soil. These forces primarily come into play during the design of retaining wall structures, but they can also be found in water-retaining structures and storage vessels. Updated October 2016.
