I am a graduate engineer. I have a steel bridge of 20 spans that includes straight as well as curved girders. To perform a load rating of this bridge in BrR, I am thinking of separating them in different units of spans with straight girders and check the straight girders only in BrR. Is this a...
Hello,
Is there a way to change the HCL or Center Line of the Bridge in AASHTOWare BrR? The only skewed abutment is the first one in my bridge and BrR assumes the centerline as HCL. I could not find a way to change that as my Reference line or HCL is a bit below the actual centerline.
Thank...
Can anyone enlighten me with the concept and process on modeling the 3 span - Simple Made Continuous steel plate girder bridges with concrete diaphragms? Apparently, AASHTOWare does not have option to choose multi span analysis for steel bridges of this kind.
Thank you.
Hello,
Could someone please help me understand the concept of Lever Rule method for Live Load DF in the following case?
- Bridge: Rolled Steel Beam with corrugated metal deck (nearly no overhangs)
- Interested in Exterior Girder
- Girder Spacing 4.5'.
- While placing the left truck wheel load...
Does skin friction of the pad come into play increasing bearing capacity? Can we add the skin friction provided the sides of the pad to the bearing capacity of the foundation?
I have seven helical piles on grade beam. The lateral load from column is acting along the length of the grade beam. The soil 7 ft underneath has very stiff clay. Would assuming the localized bending of helical piles will not occur be appropriate in this case?
