Abstract:
The C.E.B. concepts of Limit States are illustrated, as well as the choise of the verification in the space of load effects. Safety formulation based on partial coefficients is explained, with particular reference to the problem of nonlinear analysis of statically indeterminate structures and to the uncertainity of the statical model. A ductility condition for linear analysis with redistribution is described and the criteria of its derivation are outlined. The criteria for serviceability limit states are briefly summarized, with reference to cracking and to deflections.

The development of the safety provisions of the ACI Building Code is traced through the four most recent editions, since 1956, with special emphasis on the present load and resistance factor (LRF) format and its relation to more rigorous probabilistic approaches to structural safety. Serviceability provisions regarding cracking and deflections at service loads and their background are also discussed.

This paper is a summary of an important chapter of the CEB Safety Manual, published in 1975. It consists in a review of the general problems met about loads in the management of structural safety. It deals with the different qualitative classifications of actions, their idealizations and representative values. Other problems (e.g., combinations of actions specific problems during erection) are dealt with in other chapters of the manual.

The developments, relating to structural safety, which have taken place in recent years are reviewed with particular reference to the activities of the Joint Committee on Structural Safety. The interpretation of these developments in code of practice form is discussed and suggested clauses presented.

A comparision of ACI and CEB approaches to shear and torsion recommendations is presented. The author discusses the application of safety factors; shear resistance of members without shear reinforcement; reinforced concrete members with shear reinforcement; the effect of shear cracking on forces in the main reinforcement; shear resistance of concrete in short shear spans; prestressed concrete; equilibrium and compatiability torsion; designing reinforcement for torsion; and designing for combined loadings
