oa Civil Engineer in South Africa - Risk and structural design
Risk in the context of civil engineering construction is first discussed in broad terms, from an ideal or theoretical point of view, including the risk of loss of life and financial loss. The elements associated with risk are then identified, namely uncertainties in structural loading, member resistance and human error. Quantification of the risk of failure is then addressed, in a discussion of the notional risk implicit in overseas codes of practice as well as that in the proposed formulation for SABS 0160. The influence of load factors, material factors and importance factors on the level of risk is then illustrated.
