    Slab Load Distribution

    Thanks, that thread was helpful.

    Slab Load Distribution

    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...

    Sheet piling waler system design

    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.

    Sheet piling waler system design

    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...

    Sheet piling waler system design

    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...

    Stiffness of Bridge Piers

    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...

    Stiffness of Bridge Piers

    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...
