Symposium Papers

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:

Compares ACI Building Code design procedure with Comite Europeen du Beton (CEB) procedure and other more elaborate methods of predicting the behavior of tied and spirally reinforced columns. The factors of safety in the material specifications, in the load and capacity reduction factors, and in the design equations for short columns are analyzed separately. The ACI and CEB design equations for slender columns are compared with a theoretical method of analysis.

Abstract:

An effort is made to bring into focus the knowns and unknowns relevant to the design of reinforced concrete columns. Both theoretical and practical concerns are covered in an effort to distinguish immediate problems which must be solved to make the reinforced column more economical and versatile.

Abstract:

Sixty-four concrete columns were loaded to destruction to investigate the effects of tie spacing on ultimate strength. Variables included in the tests were column size, spacing of ties, strength of concrete, size of tie, percentage of longitudinal reinforcement, and position of load. Principal data obtained were failure loads, modes of failure, and strains.

Publication:

Symposium Papers

Volume:

13

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.
