Ola, sou fabricante de pinos STUD-BOLT no Brasil como faço para passar uma apresentação para o senhor ??

Great sir. Sir have you made model of bond strength of concrete. ie pull out test of concrete.

Basically, this is a new way to use locktite. Cool.

Thank you, Dr., really learning a lot from your channel, please do you have any lecture on the design of retaining wall?

Thankstm kind for yr information Sir

Interesting content, thank you sir.

Is there any literature for shear connectors? I've seen in books angulars, spiral bars, and the studs, but I haven't seen how to calculate special cases or if there's any condition for those.

Thanks.

An interesting problem with a very interesting idea for the solution. Have you done any tests with the bolts off center in their holes or holes in the plates being joined off center with each other? As soon as anyone starts assembling these in the field, the nice alignment in your experiments won't happen - if you have building contractors doing the assembly, there's a fair chance everything will be tightened with an impact wrench too 😞. Using fasteners with similar stiffness and thermal expansion properties to the materials they join would be a more likely way forward for using these materials in structural applications, as for an assembly with hundreds or thousands of bolted joints, I can't see anyone agreeing to injecting resin into every one of them unless there's literally no other possible way. A design code which makes allowances to account for the fastener properties being so different to the material they fasten but using conventional steel bolts is also more likely.

Dr Qureshi, this was an interesting video! A few questions from a mechanical designer (but not a degreed engineer): Using steel fasteners with FRP materials results in large mismatches of modulus of elasticity and coefficient of thermal expansion. With the sample fasteners and tightening torque used (M16 @ 88Nm), I got an estimated clamping force of 27.5kN, spread over a relatively small area from the bolt/washer to the FRP. This is a low initial strain for this size bolt, in a typical steel structure fabrication the clamping load might be four times as much or more. This presumes a static temperature, when in reality most environments could see a swing of say, 50C over a year. I would guess that this can lead to significant changes in clamping force even without factoring in relaxation of the FRP. Would this indicate that mechanically clamped joints in FRP would be better served with more, smaller steel fasteners with larger bearing surfaces that could have greater strain applied during installation? Perhaps including more "spring" effect, such as using Belleville-style washers? Perhaps development of reliable FRP or monolithic plastic fasteners might be more appropriate. I do think that a polymer injection as you present could still be beneficial in either case.

They made a song about this. I remember singing it when I was a kid.😂😂😂london bridges😂😂😂

You know, I am honoured the algorithm thought even a moment of this would be relevant to my interests 😂

Thanks!

For structures like canopies with corrugated sheets connected to purlins, it seems that bolt spacing requirements aren't strictly followed. Does the Eurocode's bolt spacing rule apply only to critical connections like beam-column and beam-to-beam joints? What is the rationale behind this rule?

Why is a thread check for bolts not required in Eurocode for bolt connections? How can the appropriate screw thread size be determined, and does the screw thread size matter if all other checks, such as bearing, shear, torsion, block shear, and combined actions, are satisfied?

Sri Lanka available more examples

Thanks sir, hope continue to explain eurocode -2 ( column, slab, wall). 😊

Thanks, Sir. For a fixed moment beam, it will be wL^2/12? right?

Hi, is partially threaded bolt better than fully threaded bolts as far as design strength of connection is considered, as the area of fully threaded bolts will be less than the shank of partially threaded bolts

Kind sir Can you brie Super Dead

In the provided example, you have assumed a theta value of 21.8 degrees. When designing, how to decide which theta value to adopt, whether it should be 21.8 degrees, 45 degrees, or a value in between. I think people prefer using 45 degree in design since it would give the greatest Vrd,max.

I have a simple question for you all. Democrats tout the benefits of DEI and make arguments that DEI is good for our society, and yet when a DEI hire is mentioned, Susan Rice and many Democrats find it offensive. The question is, why? Why Democrats do not want to own DEI as the preach. This is coming from a lifelong Democrat.

Reminded me of my dissertation. Thank you for sharing the information

Thanks!

Excellent insightful content Dr. Very detail.💯

I have a problem to connect a rigid wire to 3D wire beam element. I find many tutorial about how to constraint a rigid body to 3D solid. However it seems the prcedure diffrent in 3D wire? I wish if you could just give me some hint or refer me to another vedio?? Thank you so much for shearing!
