Document: 

SP26-24

Date: 

January 1, 1971

Author(s):

O. JA. Berg

Publication:

Symposium Papers

Volume:

26

Abstract:

The development of the theoretic interpretation of strength and deformation nature permits to outline two parameter points (stress levels), besides limit of strength. These objective criteria can be used while designing concrete and reinforced bridge constructions, as they influence many properties of concrete.

Date: 

January 1, 1971

Author(s):

Zenon A. Zielinski

Publication:

Symposium Papers

Volume:

26

Abstract:

On the basis of the author's research carried on since 1957, he defines strength limits of reinforced concrete beams, and strength in inclined cracking in particular. It appears that inclined cracking due to shear does not terminate the work of the beam.

SP26-39

Date: 

January 1, 1971

Author(s):

Nils-Ove Gronqvist

Publication:

Symposium Papers

Volume:

Abstract:

The present series of tests comprises about 100 tests specimens all of which had formerly been subjected to pulsating loads. The investigation is a direct continuation of the tests in (1) as the material left over from these tests was used in the present ones. The factors studied in (1) have become parameters also in this investigation together with those factors which are measured in normal static tests, i.e. yield point, breaking point and elongation. These measuring results have been compared with the static strength values of the reinforcing bar when unaffected by earlier load applications.
