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.

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.

Abstract:

Concrete Sea Structures have recently undergone rapid development, especially in the North Sea. Experience with these has shown that a number of aspects require special consideration, due to the character of the environmental forces and magnitude and combinations of loading associated with use in the sea.

Symposium Papers

Volume:

59

Abstract:

The paper summarises the current knowledge of the behaviour of concrete structures in fire. It reviews briefly the relationship between safety and economy. It recommends the acceptance of partial factors of safety covering the nature of the structure and the consquences of failure in addition to those covering materials and loads.

Author(s):

J.G. MacGregor

Publication:

Symposium Papers

Volume:

59

Abstract:

This paper reviews the philosophy of the 1971 ACI Building Code Sections on Shear and the revisions recently proposed by ACI Committee 426. The design of reinforced and prestressed beams for shear is discussed. In addition, the use of shear friction and the design of deep beams and corbels is discussed.
