Abstract:
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.

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 present series of tests comprises about 100 tests specimens all of which had formerly been subjected to pulsating loads. The investigation is a direct continuation of the tests in (1) as the material left over from these tests was used in the present ones. The factors studied in (1) have become parameters also in this investigation together with those factors which are measured in normal static tests, i.e. yield point, breaking point and elongation. These measuring results have been compared with the static strength values of the reinforcing bar when unaffected by earlier load applications.

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.

A study is made of high-quality high-strength concrete, its significant attributes, mix-design, and application of economic-strength designs to bridge members and piles, Part I was devoted to significant attributes and mix-design methods. This Part II first treats of cost comparison of concrete mixes for different strengths.
