Symposium Papers

Abstract:

Experience and some damages in the last 30 years teach that full prestressing is often not the best solution for prestressed concrete structures. Better service performance can be obtained with partial prestressing. Serviceability criteria are proposed to meet performance requirements. Cracks with limited crack width are harmless, but crack width control must be improved and this can be done by partial prestressing. Rules are given for a reasonable choice of the degree of prestressing.

Symposium Papers

Volume:

Abstract:

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.

Abstract:

The term "code" as used in the construction industry is not applicable in the same sense to the shipbuilding industry. . .This paper reviews the history of codes for concrete ships and discusses the Federation Internationale de la Precontrainte (FIP) report, "Considerations for Design of Prestressed Concrete Ships." Design of the Arco-Pertamina liquid petroleum gas facility is described briefly.

Symposium Papers

Volume:

59

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:

Besides a "Standard Method" derived from semi-empirical considerations for the new CEB model code proposes a "Refined Method" for the design of reinforced and prestressed concrete members subjected to bending and shear. It is compatiable with the design method for torsion and combined cases of bending, shear and torsion.
