I am load rating what is basically an elevated slab structure, which consists of 1) a grid of columns, 2) in one direction, a "pile cap" beam spans the columns, 3) precast panels connected by shear keys and concrete overlay sit on top of that. I am assuming that the panels act together, similar...
KootK - Thanks. That method does seem like the best way I can think of to do it. But my results give the worst case when the shorter cantilever brace end is pinned, because the longer end with more force is causing a higher compression force.
Yes, my model is incomplete in its current state and I'm curious if anyone knows the best way to complete it (i.e. what to restrain). As I said in my original post, in its current state, the waler system obviously just rotates about the corner because of the force imbalance. Also, the sheeting...
I am designing an unusual waler system for an L shaped sheet pile wall. The waler system consists of two beams welded along the sheet piles near the top, one on each leg of the "L". There is a corner brace that spans between the two beams, making each beam what I would call "simply supported...
Eric,
My company uses MIDAS, which works great for figuring out the stiffness of the bent, but I don't want to have to do that for every bent on every bridge I design... I have a great Excel sheet that does everything just the way I want it using 3EI/L3 to calculate the stiffness of each bent...
I'm trying to calculate the relative stiffnesses of pile bents for longitudinal load distribution on a railroad bridge.
I know of two ways to do it: [ol 1]
Modeling in an FEA program. (tedious and time consuming to do this for every bent on every bridge)Using n*3EI/L3 or n*12EI/L3 for each...
