SP20-03

Date: 

January 1, 1968

Author(s):

Torben C. Hansen

Publication:

Symposium Papers

Volume:

20

Abstract:

Crack formation and propagation were studied experimentally and theoretically for concrete submitted to static compressive load, to sustained load, and to pulsating load. . .Fracture mechanism of hardened cement paste is discussed.

SP20-11

Date: 

January 1, 1968

Author(s):

Amos Atlas, Chester P. Siess, and Clyde E. Kesler

Publication:

Symposium Papers

Volume:

20

Abstract:

The extent of cracking in slabs reinforced with smooth welded wire fabric is determined by the bond and achorage properties of fabric as well as by the magnitude of the steel stress. Test results show that the crack spacing is controlled primarily by the transverse wire spacing and by the size and spacing of the longitudinal wires.

Abstract:

SP20 Virtually all aspects of the causes, mechanism, and control of cracking in concrete are covered. Contracts are presented to show that in some plain concrete structures, cracking is to be avoided. In mass concrete, elaborate precautions are taken to insure that during the early life of the structure, thermal stresses, remain less than the tensile strength of the concrete. However, in reinforced concrete, cracking is inevitable . . . At times cracking is induced.

SP20-10

Date: 

January 1, 1968

Author(s):

James P. Romualdi, Melvin Ramey, and Santiago C. Sanday

Publication:

Symposium Papers

Volume:

20

Abstract:

The concepts of crack arrest in concrete and the effect of closely spaced fiber reinforcement upon fracture toughness is reviewed in order to provide a basis for the description of the specific properties of fiber reinforced concrete.

Document: 

SP20-08

Date: 

January 1, 1968

Author(s):

Paul H. Kaar

Publication:

Symposium Papers

Volume:

20

Abstract:

A brief review of past research concerning crack control is presented and a recent investigation of similitude of top surface T-beam cracking under negative moment is described in detail. Similitude of cracking is evaluated in relation to the results of tests of quarter, half, and full-scale specimens. The reliability of expressions for computation of crack width is discussed.
