Widianto, Patel, and Owen's paper titled "Design of Anchor Reinforcement in Concrete Pedestals" is another good reading on the subject. The PDF is available through a quick google search.
Typically the footing and pedestal are poured separately with the pedestal reinforcement developed into the footing. The anchor rod embedment should only be considered from below the transition not from the top of the pedestal. What height of pedestal are you considering that would make...
The force I'm worried about is the result of the pipe wanting to expand but cannot due to being anchored at this location. I wasn't assuming that the channel and wide flange were expanding due to a delta t, the pipe will be insulated and sitting off of the beam. I think I misunderstood what you...
KootK: This is one of the anchor points along the line so the pipe is not meant to move at this location and will be limited to how much the steel is displaced by the expansion force.
There are clip angles connecting the wide flange web to the column flange. I figured it would need a separate connection for the channel to ensure the load path stays out of the wide flange. Would another clip angle welded to the channel accomplish this or does this need to be a moment...
Does anyone have any good resources on designing pipe supports as anchor points in hot run of pipe? The sketch I have attached is something I've heard works for redirecting the torsion created from the pipe's expansion and the offset of the pipe center line and center of the wide flange beam...
Yes the existing slab is part of an unloading building for the coal truck. I'm not sure why the slab was shaped that way, even at the moment that edge is covered by gravel to the top of concrete.
Ron: The load is being provided by a coal truck weighing 837kips, four wheels per axle, so about 100kips per 3'x3' tire contact area. Can you explain the thrust block a little more or point me somewhere to look? The only references I could find for thrust blocks were all in reference to piping...
The difference is that we are trying to tie into an existing slab rather than pouring new construction. Also I don't think smooth dowels would do anything to help hold the slabs together besides what little the epoxy can offer. One thing I failed to mention earlier is that this area can get...
The only part I worry about it assuring the concrete remains in contact with each other. If the two slabs were to pull away from each when the concrete cures then the load is going to be supported mainly by the dowels.
I've got a new concrete ramp that needs to be tied into an existing building slab. The problem is this vehicle produces wheel loads of 100kips on a 3'x3' contact area. Can any reasonable amount of dowels be sufficient to transfer these massive wheel loads into the existing slab? We considered...
