It has long been recognized that there is a need to rationalize codes of practice for structural design. There are those who argue in favour of rationalization basically because it is a sound concept; but there are many practical reasons. On the national level, the codes in the UK are mainly based on materials, whereas most structures are of hybrid construction. These codes were drafted by experts in different fields and inevitably with different interests in the promotion of the use of certain materials. Another important factor is the different stages of development of codes at a given time. It is therefore not too difficult to appreciate the need for rationalization. The reason for adopting the present approach known as probabilistic method, however, is less obvious. Perhaps justification in this instance is hardly necessary since no alternative method was considered appropriate. Nevertheless, reliability analysis, which is the basis of this method, does satisfy two major requirements for rationalization. /Author/TRRL/
