Therefore, we have the relationship Sα1/L3, where S = stiffness and L = span of the beam. Thus, it can be seen that by halving the span the stiffness of the beam is increased eight times. Taking this a step further, it can be shown that moments will redistribute themselves through a structure such as a building or a frame depending on the relative stiffness of the adjacent members; this is called moment distribution. There is more information and an explanation on flexural stiffness in Chapter 8, which also provides details of a simple experiment showing how the end connection of a structural member can affect its strength.
9 for the more common load cases showing the deflection, bending moments and shear forces for various loading situations and end restraints. These are calculated in a similar manner to the above analysis for a uniformly distributed load on a simply supported beam. Basic theory of bending Let us consider a beam in cross-section rather than along the length of a beam. If a beam is subjected to a pure bending moment – that is a constant bending moment along the length of the beam with no shear force – then the fibres in the lower section of the beam are extended and those in the upper part of the beam are compressed.

The trussed roof, introduced during the 1960s, was becoming popular and this removed the need for labour-intensive cut roof construction. A series of single Fink trusses was placed at approximately 600 mm centres along the length of the roof, making the so-called trussed roof. Between the 1930s and the 1960s clinker or aggregate blockwork was used for the internal leaf of cavity walls.
