Section 2 Design principles

2.1 Semi-probabilistic approach

2.1.1 These Rules for concrete structures assume the use of a semi-probabilistic analysis with characteristic values of loads and strengths of materials in association with partial safety factors. Departure from the partial safety factors or other design criteria given in these Rules is to be agreed with LR.

2.1.2 Other design approaches can be accepted, subject to approval.

2.2 Limit state design

2.2.1 The aim of this design method is the achievement of an acceptable probability that the structure or part of a structure being designed will not reach a particular state, called a limit state, in which it infringes one of the criteria governing its strength, durability or use.

2.2.2 The limit state categories are outlined in Pt 9, Ch 1, 3 Limit states of design. The required loads and load combinations are given in Pt 9, Ch 2 Loads and Load Combinations and structural design in Pt 9, Ch 3 Structural Design.
