Symposium Papers

Volume:

Abstract:

This article describes a theoretical investigation of the contribution of bent-up bars to the shear strength of reinforced concrete beams, which shows that the contribution is independent of the inclination of the bent-up bars and the angle of the diagonal crack. This is at variance with the traditional Truss Analogy and means that the contribution calculated according to this theory is overestimated by about 41%. The present theory has been compared with tests and is in exact agreement with these.

Volume:

Abstract:

The proposals given in ACI 318-71 and SAA CA2-72 (Australian Code for Concrete Structures) for the calculation of shear force carried by concrete, Vc, in beams subjected in the light of test results as well as in relation to the results given by some of the recent theories.

SP42-14

Date: 

January 1, 1974

Author(s):

Man-Chung Tang

Publication:

Symposium Papers

Volume:

42

Abstract:

Tests have shown that shear capacity of a beam decreases as the absolute depth or the b/bw ration increases. Because almost all available shear tests have been performed using small beams with low b/bw ratios, it is questionable whether their results can be applied to design large and thin box girders which are becoming popular in long span prestressed concrete bridges.

Publication:

Symposium Papers

Volume:

Abstract:

This paper explains the punching shear provisions of the new British Code CP110 and compares themn and their counterparts in ACI 318-71 with test data.
