Horizontal shear at the section between flange and web for T beam
Horizontal shear at the section between flange and web for T beam
(OP)
Please share your experience/view on the matter discussed below. I am interested in the requirements of the Australian Standard AS1500.5. I am also interested in the requirements of other standards realting to this.
I am load rating a T beam bridge, and am not sure whether I need to consider the longitudinal shear at the section between the flange and web for non-composite T sections.
My interpretion of AS5100.5 is that horizontal shear has to be considered for sections through flanges only for sections cast monolithically.
I have posted a similar query on the "AS/NZS Code Issues" forum for broader coverage . Please do not post the same response to both.

AASHTO Bridge Evaluation Manual (2nd Ed.) indicates this check is only necessary with a superstructure.

graybeach, the OP never said anything about composite or otherwise, but the flange and web of monolithically cast sections do act compositely.

I agree with Hokie66. We recently did a load rating for prestressed girders that are composite with the deck slab. The section (concrete plus shear reinforcement plus prestressing effects) was rated for vertical shear, but we did not include the horizontal shear at the interface in the rating.
