Abstract:
The need for appropriate safety factors is illustrated. Causes of uncertainty in loads and strengths are listed. Probable variations in dead, live and other loads are discussed. The load factors and factors of ACI 3 18-71 are scheduled, ex-plained, and justified. The need for careful, conscientious work by designer and builder and not reliance on overly conservative safety factors is stressed. Probabilistic approaches to safety are mentioned. An appendix summarizes briefly the CEB/FIP concepts of partially probabilistic approaches to safety.
