Abstract

This document provides more detailed and more technical background information relating to this topic of the sixth call for proposals under the specific programme for standards, measurements and testing (SMT), 1994-1998. The main objective of this research is to redefine the following partial safety factors:
- Safety factor for concrete. The two main parameters related to this coefficient are the variation of the concrete strength and the control of the real strength in the finished structure. For stabilized manufacturing processes, the reduced scattering of concrete strength and the use of test procedures on finished structures or special specimens can reduce significantly this safey factor;
- Safety factor for reinforcement. Variation of geometry is the important parameter of this factor which can be improved by the precast producers;
- Safety factor for self weight of precast units. The usual safety factor for permanent loads allows very large variation for the self weight. If the weight of precast units is controlled with respect to acceptance limits this factor can be significantly reduced.
