But isn't the moment coming from the joint to column CW? Therefore, the induced moment on column's ends would be CCW.
But If I follow the diagram I encircled in the picture and draw the figure vertically, the moments drawn in the picture are CW. Is it wrong?
I was watching a video about Introduction to Earthquake Engineering and got stuck in this frame. If my memory serves me right, the moment resulting from that beam displacement would be clockwise and not counter clockwise as shown in the screenshot. Can anybody shed light on this for me. Thanks.
A noob question right here:
To analyze the reinforced concrete capacity via computation method: First, I have to know if all steel (compression and tension) yields or just some. The acquired load capacity is then compared to the required load. It's tedious work.
If I utilize the interaction...
So basically, the codes AISC & ACI which contains ASD/LRFD & WSD/USD are all elastic design with plastic methodologies to allow for plastic capacity, is that right?
I have so much to learn, but thank you for the input!
I'm talking about the range that the steel/concrete member can carry if designed on ASD/LRFD or USD, that's why I keep on defining them. I also kept reading terms like "Plastic Design" and "Elastic Design." Does "Plastic Design" means designing a member based on plastic analysis, and "Elastic...
From the responses above, I conclude the ff:
In structural analysis, we have:
(1) linear elastic (MDM, Stiffness Method)
(2) non-linear elastic (P-delta)
(3) non-linear plastic (Push-over)
In member design:
RC:
Elastic: WSD
Plastic: Ultimate Strength Design
Steel:
Elastic: ASD/ LRFD
Plastic...
Hello!
Can anybody confirm if my understanding of RC and steel's elastic/inelastic analysis and design are correct. I never found a straightforward answer from Google so maybe these are wrong. Can someone please help me, i'm trying to learn the basics.

For the given values of : ρ = 1.3, SDS = 1.10, the seismic load combinations are:
1.2D + 1.3QE + (0.2)(1.1)D + 0.5L = 1.42D + 1.3QE + 0.5L (Comb. 5)
when the signs of QE and D are the same, and...
