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 describes how prestressed precast concrete planks are constructed, specified and installed.
It is essential for structural engineers to be able to express their ideas clearly through their designs. This note describes two common techniques used to draw in three dimensions.
