Document: 

SP13-09

Date: 

January 1, 1966

Author(s):

E. Ben-Zvi, G. Muller, and I. Rosenthal

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.

Abstract:

Reports the results of tests on 30 eccentrically loaded prestressed concrete columns with an I/t ratio of 33. The degree of prestress varied from zero to 0.6 f'c. This paper examines the effect of prestressing on the loadcarrying capacity of slender columns and questions whether an optimum degree of prestress occurs.

Volume:

Abstract:

A computer analysis of rectangular, symmetrically reinforced unrestrained prestressed concrete columns in terms of a given uniquely defined stress-strain relationship is presented. The analytical results are compared with a test series. The accuracy and the range of validity of the better known approximate analyses are discussed.

SP13-10

Date: 

January 1, 1966

Author(s):

Fred M. Hudson

Publication:

Symposium Papers

Volume:

13

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.

Symposium Papers

Volume:

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.
