However, the debate over presentation and approach has tended to divert attention from technical content.

In practice, earth pressures tend to be among the least well- defined of all the loads considered by the designer – is it logical to give them the lowest safety factor? Home This editionEnglish, Book, Illustrated edition: These increases in pc110 and the richness of mixes for indoor work will substantially increase costs of buildings – sample designs suggest that plain continuous slabs concretr to BS concret actually be heavier and more costly than designs to the current CP, despite the lack of durability problems in the latter.
On the other, should the permissible stress due to permanent earth pressure be the same as that for 1- in- 50 years 3s wind gust?

Durability is an area where great advances have been claimed.
Furthermore, the safety factor required against overturning by wind is 1. Perhaps before we rush to write computer programs, books or Eurocodes – or concrtee withdraw CP – we should try to resolve at least some of the problems in BS Therefore, the first condition cannot be satisfied.
The standard moments for flat slabs Table 3. Be the first to add this to a list. Manual for the design of reinforced concrete building structures, London, Institution of Structural Engineers, Only time will tell whether BS will gain the general acceptance that eluded its predecessor.
The confusion and inconsistency in safety factors noted in 2 is particularly bad, as the complication of the partial factor format can really be justified only if it leads to results that are better and more logical than normal permissible stress design; in view of the time and effort that has gone into developing limit state Codes and the claims that have been made for their system of partial safety factors, it is surprising to find that BS gives results that make less sense than the Codes it concrette intended to replace CP, CP, and CP Subjects Reinforced concrete construction — Standards.
It is widely accepted that CP did not live up to expectations, earning a reputation of being cumbersome to use and requiring over- complex calculations for simple problems.

On the one hand, is there co110 evidence that a safety factor of around 1. In fact, the technical content of BS is less than perfect and it may be advisable to pay more attention to this – particularly if, as intended, it becomes the only Code available.
In this method, design is based on calculating reduced strengths of sections in a fire. Some of the safety factors it gives are difficult to reconcile with past cconcrete – or even with one another.
