There are several variations and conditions the designer must be aware of when determining wind loads on structures. Based on Eurocode 1: Actions on Structures Part 1-4; General Actions – Wind Actions , this note draws on the UK National Annex as it makes reference to wind speeds that are unique to the UK.
This note describes the basic knowledge required to read structural drawings.
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.
