Abstract:
Hnadling, supporting, and hauling are indispenable operations in the production, storage, transportation, and installation of prestressed concrete piling. . .The merits of the equal-moment theory as compared with the equal-reaction approach are presented.

The paper summarizes an investigation of the behavior of circular concrete hinges under the following load combinations: (i) pure axial compression (ii) axial compression and pure bending (iii) axial compression and pure twisting (iv) axial compression with bending and twisting. Ultimate load conditions of the hinge are investigated, and particular attention is paid to the initiation of cracking at the throat of the hinge. Theoretical approaches to the ultimate and cracking load behavior are proposed and verified by test results. A design procedure for the circular hinges is outlined.

In the introduction, the significance of the various concrete strengths, such as compressive, flexural, tensile, shearing, torsion, impact, bond, combined and fatigue strengths, is discussed. The two prinicpal reasons for determining the strength of a bridge concrete are as follows in the rest of the report.

On the basis of the author's research carried on since 1957, he defines strength limits of reinforced concrete beams, and strength in inclined cracking in particular. It appears that inclined cracking due to shear does not terminate the work of the beam.

Part I: Significant Attributes and Mix-Design Methods - A study is made of high-quality high-strength concrete, its significant attributes, mix-design methods, and application of economic-strength designs to bridge members and piles. This Part I first treats of such attributes as consistent density, compressive strength, high-early compressive strength, modulus of elasticity, shrinkage, creep, impermeability, and durability.
