ABSTRACT
As an illustration of structural design calculations based on BS 5628 we may consider a building having the layout shown in Figs. 12.1 and 12.2. It is assumed that the roof and floor slabs are of continuous in situ reinforced concrete construction. The structure has been kept simple to show the principle of limit state design. Only two walls above G.L.-an internal wall A, heavily loaded compared to the others, and a cavity wall B, have been considered. The inner leaf is assumed to support its own weight together with roof and floor loads, whilst the outer leaf will
support only its own weight. The design loads and design assumptions are given in section 12.2.
