How to calculate the diameter of anchor bolts that can resist tensile and shear force

[@sothattheng8624]

Thanks for your sharing! hope to see more with steel beam design in AISC.

[@joelmaim8925]

Thank you very much sir for the detailed explanation....Keep do what you do best...God bless

[@pinoyce]

Thank you

[@krnloveee]

can i ask if what part of the nscp book can I see the tension area of the bolt diameter? thank you so much

[@pamela3005]

Same question po, I wonder if you have the answer already?

[@dominiquelouisecorpuz2107]

san po galing yung 120kn?

Where is table 510.3.2 from? Also thank you very helpful video.

[@pinoyce]

It is from NSCP 2015 which is also derived from AISC 360-16 Table J3.2.

can you have an example for shear strength? is it 0.45(0.45)(248)?

[@pinoyce]

For shear strength, the solution would be like this: ΦVn = Φ*Fnv*Ab = 0.75*(0.45*400)*Ab

[@SkipToMyLouuuu]

@@pinoyce so sir 0.75(30,000) = 0.75(0.45)(400)(Ab) tama po sir?

[@pinoyce]

you need to get first the Shear Force from the structural analysis...Let's say if you have an ultimate shear force Vu = 80,000 N / 4bolts = 20,000 N = 0.75*(0.45*400)*Ab. Ab = 148.15sqm. hence, use 16mm diameter bolt.

[@arihandoko6680]

@@pinoyce the unit must be mm2 or m2, sir ?

[@querieson8534]

Pano po pag may shear at tensile force?

[@pinoyce]

For combined Tension & Shear in bearing type connections, Rn = F'nt*Ab, where F'nt = 1.3Fnt - Fnt*fv/ΦFnv ≤ Fnt. F'nt is the nominal tensile stress modified to include the effects of shearing stress. Please refer to section 510.3.7 of the NSCP 2015. Soon, I will create another video for this one.
