1 4 Live Load Reduction and Tributary Area

[@bradvincent2586]

Wow. Very good explanation. I feel like I'm learning from someone that cares about connecting the textbook to the real world

[@1963rzr]

Glad you liked it!

[@jamalnaser1933]

Thank you so much for the wonderful videos. It feels like I'm learning from a GOOD mentor at work place, which I never had, unfortunately. Looking forward for more videos. Best wishes!

Happy you liked them :)

[@ibrahimalbaz2595]

thank you very much you made me able to understand it very well through that example.

Great explanation 👏

Good Explanation Sir. Can you mention the textbook for reference

[@missyajg]

The last column you are calculating the live load for ... you have the roof load plus 2 * At (L floor). The At you use here is 960 sf, which is really only true for the ground floor column (below first floor). The col above that only carries half the trib area. However what I really want to ask is I have seen several examples worked out on line where the At is only from the floor level that you are evaluating (therefore the cols at each floor level do have the same influence area, here they would be Ai = 4*480). Your example has the influence area increase as each floor level is added on. I can see an argument for either case based on how the code reads, but the answers come out differently especially for taller buildings. Thoughts?

[@betaleducation6060]

What about the concentrated loads in the table? Don't we take those for our calcs?

[@MOATHALSHIBLIvfx]

thank for the great course I noticed that you are using both imperial and metric units. But, my lecture said the metric unit better and accurate.! Is that correct?

[@1963rzr]

units don't matter. Both are included in the spec

[@MOATHALSHIBLIvfx]

@@1963rzr thank you

[@mahnoorfatima5761]

At 18:05 , I believe, the formula for influence area should use At instead of 2At. Please correct me if I am wrong.

This has always confused me. How come the width of the tributary area for girder is 16 feet? I understand that you take half the distance from one girder to the next. But how do you determine the other length of the girder? Thankyou

[@1963rzr]

I don't understand the question. could you please be more specific?

[@osuwatchdog7154]

tHANKS sIR THIS IS WELL EXPLAINED

Is it 8x20 or 8x40 in beam 1?

[@maetheresebatusin8866]

If the given is a 3 story building, will you automatically 0.4 for column reduction? thank you!

[@1963rzr]

not necessarily

[@matthewarnold4948]

I realized there is a 12-20 range for Lr what does it refer to? especially since our calculated Lr would exceed that?

[@matthewarnold4948]

This is in regards to the LoR1R2 formula in the ASCE manual

[@1963rzr]

I don't understand the question

[@islemekrani597]

Can you share me long information at 5.23 minutes ? :)

[@1963rzr]

Hi, you just have to google for ASCE 7 chapter 4 minimum load design live loads
