@MinthJulep Respectfully, I addressed @HTURKAK in my comment. Still your point is somehow valid, if you have their membership, can you please send the query on my behalf? I don't have the membership. And this forum is a place to discuss issues with experienced engineers, if someone already know...
Thank you @HTURKAK and @MintJulep
@HTURKAK I don't understand why code committee has introduced point 1,2 and 3 when result solely depends on point 4 (Expansion index). In UBC 97, there was only one criteria for a soil to be expansive that is expansion index only.
Hello everyone,
Please have a look at the attached image of IBC 2021 clause.
I have the following doubts:
It says all four criteria need to be fulfilled for a soil to be expansive whereas it also says if test mentioned in point 4 is conducted then points 1,2 & 3 not required to be fulfilled...
Hello,
Please refer to the attached image of storm water drain section.

Hello,
I have to design a connection of steel beam (wide flange) to a existing RCC column, refer attached photo to get the idea of what I am trying to do. For the design of end plate, I am thinking of designing it like a simple base plate of a column subjected to moment and horizontal force. Is...
I am so disappointed that how this issue is left unattended by ACI and other American codes (as I am only aware of them).
@jjl317 and EngDM The designer (vendor) is using "Rawlplug" bolts so I tried their software but there is no block masonry option available there. They are only dealing with...

HELLO,
I am looking into this ground + 1 floor building's ETABS model. I want to ask your opinion on what should be the floor height considered here in ETABS? Please refer the following image
What I am thinking is it should be 9'6" (5'6"+4') since it would be the design length of the column...
Hello,
I have to provide a plain concrete mass to make a trench for cables. Length of this trench is 15'. Sectional dimensions can be seen below.
What I am concerned about is whether there be enough shrinkage in this 15' long mass of concrete to develop cracks?
How can I check it? What would...
I have 2 different soil investigation reports for the same site. One done 3 years ago and one recently. One of them provided gross allowable bearing capacity while other provided net allowable bearing capacity. The structure doesn't have any basement, just simple isolated foundation.
If I use...
@DoubleStud In case of scenario "2", what is the approach behind putting the base slab directly on the existing soil instead of a competent strata deep down? Did you do any soil improvement? usually on internet I have seen base slab resting directly on natural ground level (with zero or minimal...
Hello,
I have a question regarding box culvert. Please have a look at the attached image.
I have to design a box culvert for the condition shown in "1". This is the natural ground condition (not excavated). Basically it is an existing path of water flow.
The issue is where should I place my...
A propped cantilever element (fixed at one end and pinned at the other) loaded with triangular load should produce the bending diagram as following:
Now I have an ETABS model of an underground septic tank. Since walls are connected to foundation at the bottom (fixed), with slab at the top...
