Hey I have something similar I'm trying to solve, would you mind heling me out. i have a circular flange connected to a base, im trying to determine the layout and anchor bolt size.
Very good video....I have a question...when you say 3 anchor bolts....you actually means 6 anchor bolts ? ...A set of 3 anchor bolts at each side of the base plate ? ...Hence the total bending moment is actually distributed around 6 bolts ? ....Please clarify. I did a total calculation for 4 bolts (total)...and it looks like this .... 40,000 -800*5 - 2*F1*8.5 - 2*F1*1.5/8.5*1.5 ... For this the force F1 is the tensile force at the left side of the column over the bolts...If you solve for F1 = 2,053 lbs ...which is ok for the chosen bolt of 10 kips.
Since my background is in chemical engineering ... it took me a few minutes to understand that the force in the bolts that are on the right hand side of the bending moments were not included according to the formula shown in Excel: Ft = (Mc - Fa * N / 2) / (N - edge) ... So I am assuming that the bolts on the right side contributes very little to keep the column from tipping as shown in the force diagram. If the bolts on the left side of the column break ... then we have a disaster!!! Have you done any work about how to avoid the bolts peeling off from the concrete base ? Thanks.
You bet!!!! If the bolt don't grab the concrete structure properly...you have a problem. The tensile strength of the bolt might not even reach the design force since the anchor bolt peeled off from the concrete base and that will be catastrophic. There are table that clearly indicate how deep an anchor bolts need to be buried within the concrete for a given force.
Thanks so mucho, excellent explanation! , Can you share your spread sheet or how can i get it?
Well explained, I'll have to set up my own excel sheet. How does this change if the column and anchor bolt layout is circular?

Well Done!!
You did good job. I think in your calcs ASD method is used, why did you compare with the LRFD value from AISC table?

Well played bro.Kindly share the excel sheet
Good. Will try to develop one of my own.
can you explain why you calculated Moment of inertia by b=width ok but Height = Length (why considered height as length)
Hi, I like your video as I am trying to get into sizing base plate for my own projects, would you consider sharing your excel file ?
nice very interested concepts.keept up
could you share the template please
You too good at explanation....could you please share your spreadsheet or inbox me for a project?
Nice video, can you please share the excel fike
Can you share the file ? Video is awesome.
would you consider sharing your excel file ?
Excellant
excelente planilha....uma pena que voçê nao usa o sistema internacional "SI".....voçê usa polegada.....fica complicado pra maioria ...dificulta tudo
@TopDogEngineer Is there a miniimum code requirement about the distance of the edge of the baseplate to the edge of the concrete pedestals?
How can I get a copy of this spread sheet. Please let me know
Do the equations change if the column is circular?
just one equation
can you please share excel file
Very useful. Thank you
Your Welcome!
Hello, how do i get this calculator, can you share it please?

Hello, how do i get this calculator, can you share it please?
How to calculate the length of anchor(the embedment length of anchor into concrete) ?
Do you have the source material based on which the excel is produced?
I found an issue designing non symmetric beam base plate connection can you help me out
Is there any way to know how deep the anchor rods need to go ?

Loved it !! Thanks a lot.. :)
Glad you liked it!
@@topdogengineer8440 how I get this template
Can i have a copy of your excel? Hoping :)
how we can download this program?
How do u get copy of the template?
how much is you excel form?
Sir, why some design have stiffeners in base plate?
1. To lessen the bending stress on base plate.
2. To increase joint connection of post to plate.
@@yududoy5429 thank you
Hi Sir please sent me this excel sheet...
Please share these file
Hi dear do you have spread sheet with metric unit
