Very helpful…especially for someone like me who is an intern and currently undergoing undergrad degree trying to reconcile all the concepts I learnt in class with the field❤

I'm looking to replace hardwood bed frame nonsense roof beams in my garage, and doing some back-of-the-envelope structural analysis with your guide was really helpful. It's remarkable how strong 80x80mm hardwood beams are, I seem to need 120mm section i beam to match the strength!

That was terrific! I remember it Iook several tutorials to get to grips with the BS equivalent, isn't the internet wonderful!! Definitely subscribed......thanks

great video, very informative👍

Hi Dazz, this is really helpful, thanks. But I was wondering if it's normal not to consider the beam's self weight in the calculation? Or you'd reiterate again with the beam's weight?

Hi! I was referring Design of Structural Elements by Chanakya arya to brush up my basics. In this book, steel design section, they did designing some different way. They did not use the blue book like you did. Can you please tell me where should I start to learn from the basics. Thanks in advance.

Hi there, in which document did you get the deflection limits for the combined load, dead load and live load? Could you specifically direct me? Thanks

Great stuff, looking for a calc to build a small gym with 150mm H beams

Do you have an example of two beams supporting an external wall? One resisting the brickwork, one resisting the blockwork and roof weight. Should the beams be tied together, if so, how?

Great videos, keep up the good work is really helpful, thank you. A wee question, why did you take the deflection limit as 200mm and not 20mm when calculating the second moment of area?

its 20mm, just my handwriting looks like 200 😛

This is so helpful! Thank you. Please do more examples of column and beam design for steel and concrete. Do you have any textbook recommendations where they give a lot of examples? It's so time consuming trying to find examples that use EC2 and EC3 :( our uni doesnt provide as with much examples or solutions so half the time I dont know if Im doing my beam and column designs correctly or not.

I’ve done a video on books so worth checking out. Concrete centre or concrete society does lots of examples for concrete design. SCI has plenty of documents with good examples for steel.

Can you design a cantilever beam connection with one support example with a pinned or and a moment connection? Also a wood column subject to overturning from wind. There is much confusion on holding column down on open porches. Thx

Sure. Just fyi, you can’t have a cantilever beam with a pin connection.

Hi Daz, I think with the moment of inertia required, the deflection required should be 20mm not 200mm. Or am I wrong in this. Thank you for the great video. Keep it up as always.

It would be great to see how you would design this same beam if the masonry above was existing. Would you increase the size of the section to minimize cracking in the existing masonry or would you pack out the beam? If so, how do you calculate the size of your beam packers and at what spacing do the spacers decrease in size as they approach the support ends? This is something I’ve always struggled with, thanks.

Good,,, I didn't see BS 5950 applications??

In your example you've used the combine deflection limit of 200 yet your calculation was for the live loading of 24kn, is there a reason for this?

Hello, the weight is 5.5 tons per meter. Which type of iron can bear this weight? Thank you

Hi Dazz, Why is it that you and others use (wL^2)/8 as the formula for moments in a simply supported beam with a UDL but the red book (page 70) and other sources suggest using (WL)/8. Are these the same formulas? if so what how does (w) relate to (W)? And which one should I be using? Hope my query makes sense, cheers.

So small w is kN/m and W is total load in kN. So to get W you do w multiplied by L.

That was confusing me! Who knew that there was a difference between W and w. Never seen that mentioned in any of the books I’ve read. It’s one formula or the other leaving me baffled.

Can you explain why deflection is 20*10^4 please? Around 7 mins in?

I was wondering where you got the "I required" formula?

@ImranZakhaev9

Жыл бұрын

It’s the formula for deflection rearranged to solve for the “I” given the deflection limit. The deflection of a beam under uniform load is: d = (5 * w * L^4) / (384 * E * I) Where: d = deflection (m) w = uniform load (kN/m) L = length of span (m) E = Young’s modulus (aka modulus of elasticity) (Pa) I = second moment of area (aka moment of inertia) (m^4) Some use units of mm, MPa, etc., but I always use base units of m, N, Pa

Hi, if length of steel beam is 5000 mm including 200 mm bearing in each side. This means length of clear span is 4600 mm.which length will use in design. Clear span length or full length of the beam? Please advice. Thanks.

@EverydayDazz

I would take the bearing centre length. So 4800mm.

Hi, please I had been asked to design a perimeter beam of a two-way-slab How do I go about this?

@EverydayDazz

Жыл бұрын

Attribute the load correctly to the edge beam, it depends on the dimensions of the slab but typically you can attribute a quarter of the area to the edge beam.

I reg formula is wrong. he is using 5000lenght in mm and then gets the result in cm? The 200*10^4 should be 200*10^3 i think to make it work

w= PSF load. W = total tributary load/ : PSF x area

So basically if the deflection is okay, I can choose the beam right?
