Integral Bridge Supports
I have a few questions regarding the boundary supports for integral bridges:
1. When selecting the 'Pile Spring' soil spring type, a ground level input is required. Does this mean the ground level behind the abutment (at deck/road level) or the ground level in front of the abutment (underpass road level)?
2. Is there a recommended value for the 'Coeff. of Subgrade Reaction'?
3. If an abutment has an L shape, is the height taken from the top of the abutment to the very bottom of the section or would it be taken to the top of the horizontal section?
