Abstract:

Longitudinally and circumferentially prestressed cylinders and columns of varying slenderness were tested to destruction to determine what influence the amount and kind of prestress had on ultimate load and stability characteristics. Previous tests of triaxially prestressed elements were reviewed, and their findings compared with results of the present study.

Abstract:

Two equations are proposed to define approximately the shape of load contours in square and rectangular columns. A method for constructing the interaction diagram for any position of the load is explained. Loads predicted theoretically from such curves are compared with 50 test results. The method is restricted to columns containing eight or more bars evenly distributed among the column faces.

Abstract:

A theoretical analysis of the buckling of eccentrically loaded long reinforced concrete columns with abrupt change of the cross section. The solution is based on the plastic theory. An experimental program checked the computed ultimate capacity values of the theoretical analysis.

Abstract:

Reports a study of seven rectangular frames loaded symmetrically so that the columns were bent in single curvature. The object of the investigation was to study and evaluate the strength of the columns as integral parts of frames. For columns in single curvature, frame action permitted 5 to 15 percent more axial load capacity than that predicted without frame action.

Abstract:

Tests on eight columns bent in antisymmetrical double curvature with h/t = 27.3 are discussed. The columns with small end eccentricities approached a single curvature shape and an unstable condition at failure. The columns with large eccentricities remained in the double curvature shape until failure occurred in tension at the point of maximum applied moment.
