Thank you rapt for your explanation, this is what I need to kick some butts :)
Regarding your last pair of lines, we got around this issue by applying more stress to the 14-strand tendon, so instead of jacking the tendon to 75%Fpu as the design requires, we jacked it to 79.5%Fpu, which reduces...
Dear fellow bridge engineers,
I'm currently working on a local bridge project which employs precast, post-tensioned girders, and the other day I had an argument with the consultant and my prestressing sub-contractor (Dywidag) about the permissible stresses in stressing strands and it turned out...
Hi Bridgebuster:
I just checked the rest of the details of the submitted girder and I found what you talked about; there is a sufficient number of shear connectors coming out of the girder into the concrete topping and sufficient longitudinal bars coming of the precast panels to develop with...
Hi all!
I'm a bridge engineer at a local company and my boss assigned me a task to check the design of one of our projects and I'm confused a little bit about the type of girders we have here.
The girder section is a non-standard Precast post tensioned girder which has a shape nearly as an I...
Hi all!
Last time I provided shop-drawings the Consultant of my project (which is a concrete pre-stressed girder bridge) he argued about the location of the approach slab with reference to the abutment mirror (the abutment vertical stem which has a lesser thickness than the abutment main load...
Hi All....
Right now I'm preparing shop drawings for a new bridge and I'm having some trouble with the quality of the original drawings made by the designer and I have to figure out a lot of stuff from these poor-low-quality-somehow-useless drawings.
As of now, I'm reconstructing the lost...
