How to Calculate the Capacity of a Steel Beam

[@alphamale8138]

Such a great channel . I wish I paid you instead of my prep class .

[@maiwandmomand9989]

This was my first video of Kestava, liked and subscribed. I will be learning from your content, so thank you so much!

[@Kestava_Engineering]

Welcome aboard, grab a seat in the auditorium and grab some popcorn from the back! Don't let Jose bother you to much.

[@aztecamechanicalelectrical2103]

THANK YOU VERY MUCH FOR SUCH A GREAT LESSON !!!!!

[@Kestava_Engineering]

Glad you liked it!

[@katiedietz8471]

What would this look like if the left end was a moment connection? they don't have a table for this one in the trusty ole steel manual.

[@DrissaOuattara-t4r]

very nice explanation and easy to follow Thank you so much

[@Kestava_Engineering]

You are welcome!

[@scottyausman1931]

Really well done in showing the step by step process of solving the problem. I do have a question, however. When solving for shear you got 112.5 K. That's .9*Fy*Aw*Cv1, but my understanding was you're supposed to use the 0.6 to make it 0.6*1.0(you corrected this)*Fy*Aw*Cv1 which would be 75 kips. Obviously it still passes, but I'm wondering if I'm missing something here. Thanks!

[@Kestava_Engineering]

Scotty ausman your absolutely correct! nice catch. I have shown the equation properly but did not multiply by the 0.6. 75k is the correct shear capacity

[@ngimatashi]

Very minor correction: In the (Aw= d*tw) you chose tw as .250 inch which would be for W10*19. W10*15's tw is .230 in which ultimately gives shear capacity at 62 kips. Thank you for doing this. I am trying to get back into steel design and I really appreciate what you're doing.

Perfectly done Keep the good work Thanks

thank you will do!

trying to teach myself engineering. this is a great video been wrapping my brain around steel calculations and I have a steel manual aswell so it works out really well u teaching me like this i can flip threw mine and do the same as you compared to most videos... I start to get confused by all the variables in the equations is there anywhere in the steel manual that tells me what the variables stand for? subscribed!

[@Kestava_Engineering]

in the red steel manual check out the symbols section! 16.1-xxvii thanks for joining the team Tom! pumped you're here

[@edgarteran8939]

Hey I just found your channel and I love your videos keep them up. You should do a video series on you designing a building from top to bottom.

[@Kestava_Engineering]

ambitious idea, and I absolutely love it. Im working on a better office setup right now and when thats done i think i could pull off recording something like that. stay tuned

[@Bobgavana]

Question - Why Lb is 15 feet if the flange in compression is braced by support and doesn't move out of plane?

[@S5Nasty]

I enjoyed watching your videos! Happy that i found your channel! Quick question, for flexural members, in what instances do we design using Plastic modulus(Z) versus Section modulus(S)?

[@Kestava_Engineering]

Ken that's a really great question that I'll admit I don't have the best answer to so I don't want to blatantly say something incorrect. Let me dive in and get back to you. make sure to remind me!

[@intelligentcreations2848]

@@Kestava_Engineering you never answered this question and I also would like to know your answer.

[@DmechDesign]

@@intelligentcreations2848 In Canada we have Class 1,2,3,4 sections dictated by the b/2t criteria (at the 7:27 mark, where he talks about compactness...same idea). We use Z for class 1 and 2, S for class 3 (and sometimes for 4). Rich, thanks for the videos!

[@muhammad8378]

Refer to Structural Steel Design by Jack McCormac - Chapter 9.

[@sambot4547]

Why we need to use ASD method for WOOD, is there is any particular reason??

[@Kestava_Engineering]

got me there! not sure

[@Structure-Dubai]

Sir today i have to design a 6 meter cantilever I section for scaffold structure nearly have to take 10 KN at the free end. But the section i got is much bigger, like 457x19... if i tie it with rope at a distance of 1 m from free end, what you will think, it will be a good choice?

[@Kestava_Engineering]

Any know how much 10KN is in LBS? (silly American over here)

[@Structure-Dubai]

@@Kestava_Engineering I HAVE DESIGNED IT BY TAKING A UNI I SECTION OF 251.4X146.1X31, ATTACHING A STEEL CABLE OF 24MM AT A DISTANCE OF 1.5 M FROM THE FREE END. THE ANGLE IS VERY FLATE LIKE 24 DEGREE, THATS WHY TENSION IN THE CABLE IS MUCH HIGH. THATS WHY I HAVE TO TAKE A CABLE OF MUCH HIGHER STRENGTH. DEFLECTION IS NOW BELOW 10 MM. 10 KN = 2248 LBS

Awesome... Thanks and many blessings

You are so welcome JR!

[@majidsaednia3991]

Hi, how can I find the area of the steel beams in AISC manual and also how can I find the self weight of I beams in AISC? Thanks

[@Kestava_Engineering]

property tables in the front of the manual - also the second number for a steel WF is the weight per foot of the member!

[@andyeash1730]

Thanks! Weird question. What kind of pen are you using that erases so cleanly?

[@Kestava_Engineering]

Frixion erasable pens! they are the only thing I use anymore

[@andyeash1730]

@@Kestava_Engineering thanks!

[@chappyaugusto]

is there any chance to get that book i would apresciate any info tanks,

[@Kestava_Engineering]

Hi Carlos, unfortunately I cant send the code to you as it would breach the AISC's policy. sorry about that!

[@OmarSophi10]

Hi, how can I get the manual book online for free? Thank you

[@Kestava_Engineering]

not sure unfortunately :(

[@countrylover3169]

sir how much load can a *16mm TMT Bar* can hold safely? My weight is 75 KGs, can I hang safely in it? I wanna make a bar for *pull-up* exercise, plz reply...

[@Kestava_Engineering]

country lover - if the bar is made of 36ksi grade steel and it is a solid bar (not a pipe) the bar is sufficient for you to use as a pull up bar. I recommend the bar not be more than 1.2m long and that you properly secure the bar at the ends into a strong support system or walls.

[@33cmane]

Hi, can you make a Video on Joist Girder Design?

[@ajmecacumu]

Hey Rich, I noticed bf/2tf is 7.41 for w10x15 in the property tables. Just wondering why the length to thickness ratio from table B4.1b calls for b/t and not bf/2tf? You are correct since I have it scratched into my steel manual from coolage, but no idea why b/t is assumed bf/2tf. I also have a scratched in note saying lambda = bf/2tf = b/t in the margins of table B4.1b in case that offers any insight. I just found eqn F3-2 on pg 16.1-49 defines lambda as bf/2tf but nothing further linking lambda to b/t in table B4.1b... wildly unclear to me! Cool job on your videos my man! You have my support, Team Kestava woot woot! -JD

[@Kestava_Engineering]

HI! - if you look at the definition of b in tables B4.1 - b is actually 1/2 of bf. thats why they show bf/2tf in the properties section

[@mayqassim6241]

will you please add videos about how to design connections

[@Kestava_Engineering]

yes MAY!

[@kazisayem7882]

I NEED THAT STEEL MANUAL. CAN ANYONE HELP ME TO GET IT ? I AM FROM BANGLADESH.

great video

[@Kestava_Engineering]

Thanks!

[@brodeesmith]

How would you design a beam that has a cantilevered slab attached to it? The beam in question would act has a header in a wall and have a pergola cantilevered from it. thank you in advance..!!!@@Kestava_Engineering

[@robertd6925]

Are you for hire to do calculations? I have a project that I'd like to have a 16' clear span for.

Hi Robert, feel free anytime to reach out via email that i provide in my page details / on my descriptions in my newer videos. Lets discuss!

[@jesusmillot1726]

Great video sir, You should get into continuous and isolated footings design

[@Kestava_Engineering]

Hi Jesus - great idea, i do have a 2 part isolated footing example in my concrete playlist! I should update and do a continuous footing design. thanks for your suggestion!

[@geotechniq]

Really good, but it is more convenient if you can use the Metric system :), Btw, thanks for sharing.

[@Kestava_Engineering]

GASE - I will get a few videos up using the metric system! I've done work overseas before so ive had to use the metric system but im no pro!
