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.

Symposium Papers

Volume:

Abstract:

The paper extends the application of A.L.L. Baker's ultimate load theory to the design of non-prismatic continuous girder and rigid frame bridges subjected to rolling loads. It deals mainly with two new aspects: (1) determination of influence lines for the rotation of 'plastic hinges' and (2) calculation of influence coeficients for non-prismatic members.

Document: 

SP26-38

Date: 

January 1, 1971

Author(s):

Nils-Ove Gronqvist

Publication:

Symposium Papers

Volume:

Abstract:

In the present investigation, the steel quality and the profile of the reinforcing bars have been studied. . .Four different steel qualities, three types of bar profiles and two different degrees of wear on the part of the rolls have been studied.
