A comparative analysis of civil engineering codes of practice, cp110 and bs8110 on distribution of load on a beam supporting a two-way spanning slab

Abstract

This paper presents a comparative analysis of provisions of British Standard Institution (BSI), Civil Engineering codes of
practice, CP 110 (1972) and BS 8110 (1985) on distribution of load on a beam supporting a two-way spanning slab. A plan of
typical two-span, two-way beam and slab layout was adopted and analyzed differently using the provisions of the two codes of
practice. It was clearly observed that using BS 8110 both the support and span moments for beams supporting discontinuous
edges are lower, while they are higher for beams supporting continuous edges. The shear forces at supports obtained are lower on
both cases with BS 8110. There is therefore a net advantage in economy of steel in the use of BS 8110 over that of CP 110.
