This part of BS 8110 has been prepared by Subcommittee B/525/2. It is a revision of BS 8110-1:1985 which is withdrawn.
BS 8110-1:1997 incorporates all published amendments made to BS 8110-1:1985.
Amendment No. 1 (AMD 5917) published on 31 May 1989;

It also includes changes made by incorporating Draft Amendments Nos. 5 and 6 issued for public comment during 1994 and 1995.
Amendment No. 5 detailed the insertion of various references to different cements used in concrete construction, covered by BS 5328 and the recommendations of BS 5328 for concrete as a material, up to the point of placing, curing and finishing in the works.
Amendment No. 6 dealt with the change of the partial safety factor for reinforcement _m, from 1.15 to 1.05. It has been assumed in the drafting of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people.
This part of BS 8110 gives recommendations for the structural use of concrete in buildings and structures, excluding bridges and structural concrete made with high alumina cement. The recommendations for robustness have been prepared on the assumption that all load-bearing elements, e.g. slabs, columns and walls are of concrete. In a structure where concrete elements such as floor slabs are used in conjunction with load-bearing elements of other materials, similar principles are appropriate but, when adequate robustness is provided by other means, the ties recommended by this code may not be required.
