Abstract:
SP59 As a part of Acl’s recognition of the U.S. Bicentennial in 1976, a special international symposium was held for the express purpose of cross-pollinating U.S. and European ideas of concrete design, with particular reference to the ACI Building Code. The 20 papers presented in this volume were developed from the symposium and follow its format, covering limit states design, shear and torsion, and special concepts and new applications for prestressed concrete.

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 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.

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.

Recommendations for the design of prestressed concrete flat slabs being prodcuced by the FIP, although taking into account the Recommendations of ACI Committee 423, must also be in accord with the limit state design philosophies on which the new CEB/FIP Model Code will be based. Alternative methods of calculating the ultimate flexural and shear strengths are considered. Cable distribution and progressive collapse after accident damage are examined. The paper describes also the structure of the FIP Working Party, which would welcome technical contribution from designers with experience in this field.
