Document: 

SP20-09

Date: 

January 1, 1968

Author(s):

J. Douglas Lindsay

Publication:

Symposium Papers

Volume:

20

Abstract:

Cracking in portland cement concrete pavement is a problem in conventional pavements, both plain and reinforced. Efforts to control cracking involve the use of transverse joints. In effect, natural transverse cracks are replaced by man-made crack. But joints also have undesirable characteristics.

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.

Publication:

Symposium Papers

Volume:

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.

SP20-12

Date: 

January 1, 1968

Author(s):

Edward G. Nawy

Publication:

Symposium Papers

Volume:

20

Abstract:

Most existing research deals with crack width studies in beams and one-way members. This investigation covers the effect of two-way action on crack width development, crack pattern evaluation and crack width control.

Document: 

SP20-06

Date: 

January 1, 1968

Author(s):

Peter Gergely and Leroy A. Lutz

Publication:

Symposium Papers

Volume:

20

Abstract:

Information from six experimental investigations for the side and bottom crack width of flexural members were analyzed statistically with the aid of a computer. A large number of equations and variables were examined. Two equations were proposed that best fit all the experiemental data to predict the most probable maximum crack width in reinforced concrete flexural members.
