11-02 - Example 2 - Moment-Axial Load Interaction Diagram for Reinforced Concrete Column
ฝัง
- เผยแพร่เมื่อ 19 ต.ค. 2017
- This example goes through how to create a moment-axial load interaction diagram for a reinforced concrete column. The points found in this example are (A) pure compression, (B) balance point, (C) pure flexure, (D) pure tension, and (E) tension-controlled.
Doctor u are so much great.
I never saw before like these accurate explanations.
Thank you so much for your help.
Greaaat work excellent. It was so useful for my structural fire safety homework thank you so much again.
Good Lecture. It is explained clearly and step by step.
Thanks for the detailed example. Really helpful.
Thank you sir very helpful to my study.
At 8:44, shouldn't the lever arms be measured from c, rather than the PNA?
At 14:16 you have C_s1 = .003(29000)*((3.4-2.5)/3.5) = 92.1 but those numbers equal 23.029? Or is there step in there I'm missing?
Just forgot the As1=4 sqr in
.003As1Es(c-d’)/c= 92.1
Great explanation and Awesome job. Thank You!
Is this analysis true for both short and long columns?
Life saver❤️
I think measurements are referred to aci code.
Am I true?
I wanna be sure to program it on excel sheet
well done
At Start of video you mention PNA is at mid height. Really so for RC?
Sir what is plastic neutral axis? Is there a elastic neutral axis too?
Thank you
Sir, when doing load-moment interaction I should make my own column section?
Shouldnt the comp. Force in the steel be
4(60)-4(0.85)(4)
I agree, I see that on all text books Cs1=As1(fs1-0.85 f'c)
How do you calculate for moment and axial load between point A and B?
You can select a "c" that is greater than the c we found for point B. Another common point found on the diagram is where there is zero tension in the tension steel (c = d). If you set up a spreadsheet, you can find the points associated with many different c values.
@@davidgarber1664 sir please reply, the zero strain can be higher than d? and how do I input c for the value between point A and B.
How did you find Ecu ?
is that according to euro code ???
