Agreed with the use of high load polystyrene. As JAE suggested, due to petrochemical exposure, I can propose the use of a vapour barrier to protect.

Thank you for your input! I will suggest the use of a vapor barrier for protection as you proposed.

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...

Thank you both for the valuable information! Greatly appreciated :)

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...

@gusmurr - I used RisaBase for the plate design.

@dik You bet! Again - I just got handed this and first thing I saw is "how are you going to access those bolts... ". I spent an hour on a quick analysis to get a feasible baseplate that met the anchorage design. Now that I agree we can tighten, I can burn a couple more hours sharpening the...

Hi All, Thank you all for the input. I am in complete agreement that the anchor arrangement is wrong (or not efficient let's say) - but again the foundations and anchor bolts are complete and I am unable to change this. I was not part of the project when the foundations were designed as such...

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 -...

Thank you all for your inputs. These were my initial thoughts, but the client is adamant that there is no issue. I will look into options of covering / preventing ingress was water.

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...
