Hello.
I have a truck loading slab that is susceptible to frost heave (3'-6" frost depth). One engineer is recommending the following to mitigate potential frost heave, but I have my reservations:
1. Place 2 ft of CLSM (flowable concrete fill) below the slab. The intent is this fill acts as a...
Hello,
Can someone please direct me to where I can find the section sizes used to great standard Open Web Steel Joists? For example - in the standard joist tables, they list multiple section designation (ie. 16K3, 16K4, 16K5, etc.) but what are the different sections that make up the K3 vs K5...
Hello,
I have a heavily loaded column with 8 anchor bolts. The foundation and anchor design was done by others (prior to me on the project) and is already IFC. I am tasked with finalizing the steel structure only. So regarding why the anchors were laid out a certain way - I am not able to...
Hi All,
I have a question for calculation weak story shear in an OMF.
Assuming we have strong-column, weak-beam scenario, the story shear capacity = Mb / story height.
If we have two different beam sizes at top and bottom of the column, do we then do (Mb,top /2 + Mb,bot / 2) / story height...

Hi All,
My Client has an existing concrete slab that he wants to cut back by approximately 2 feet. The slab is 12" thick and 48" wide, with a single layer for rebar at the top and bottom.
Cutting back the slab poses no structural concerns. I am just wondering how we should finish the cut end -...
I have a situation where we have a buried concrete tank. During the construction season winter months, this concrete tank will be open to atmosphere, can collect water, and then that water will freeze.
Does the freezing of a couple feet of water at the bottom of the tank pose any risk? The tank...
Hello,
I am currently working on an oil and gas project, and the contractor wants to use engineered shims under the steel column base plates prior to grouting. My question is: is there a maximum area of shim allowed, as a percentage of base plate area, beneath base plates? My concern is that is...
Hello,
Can someone provide a physical interpretation of what stress intensity describes? Also, how does stress intensity differ from stress concentration?
Hi,
I am currently modelling a 3-point bending problem of a pipe. The pipe is supported on either end by a saddle with a load saddle in the middle to apply displacement constrained loading until failure. Both the support and load saddles are modeled as rigid bodies. My issue is that the support...
