Understanding Interaction Diagram of RC Column - Tagalog tutorial

This video shows step by step plotting of Interaction Diagram graph. The intension is to help Designers in figuring out the resistance of RC column against the result from structural analysis.

I just would to make a comment regarding the compression force due to concrete where in your video @15:06 you have bd(0.85f'cβc). but actually is not d that you should multiply with the width of the column, b. Its actually the value of "a" only to make your compression force equal to 0.85f'c(a)b and since a=βc, the resulting compression force due to concrete will become only equal to 0.85f'c(βc)b. and another thing, from the ACI318-14 and NSCP2015, its already 0.65 reduction factor for tied rectangular column and not 0.70.

very well explained sir sana ma view rin ito sa mga student , ang laki tulong..

[@borisjoshuateodoro969]

Hi sir JSDesign_EngineeringTV, maraming salamat po dito ang laki po ng tulong niyo. Sir tanong ko lang dun sa computation ng Pn, sa formula po ninyo is bxdx0.85f'cxa. Bakit pa po minultiply sa d? di po ba bx0.85f'cxa lang? magiging cubic na po kasi yung bxdxa. Salamat po sir kung masagot..

Code important guide pero pag dating sa actual si client n gusto Ka ipitin gusto mo din makuha ung project s hirap Ng buhay ngayun irereduce mo factor of safety depending on experience and lakas Ng loob depending on many factors in life haha

Please discuss how to design composite column. Thanks and more power.

Sige po isasama natin sa list yan

Sir anong webcam po ang gamit nyo at mike.

[@enricoescobar8234]

Well explained sir. I'm trying to formulate the exact graph for the interaction diagram regardless how many bars are present, but it's very very complex. It all comes back to these basic points of consideration for the simplicity of solution.
Tanong ko lang sir for point C - pure moment. Should that be c & a = 0? The stress/strain diagram will be a triangle with pure tension only moment about the outermost fiber of concrete. Iniisip ko po kasi sir yung condition to get that c & a value. Tyia sir

[@AL-fy2oc]

I think yung pure moment means, Pn=0. Hence, there should be resisting force against tension steel so a and c has a value po. Ang di ko lang maalala is kung bakit dinisregard yung compression steel, as if designing a singly reinforced beam, altho this is conservative naman. :) Sana nakatulong

Nice sir ,,,,Thank u ..

galing nyo sir,thanks po

Gudpm po boss.ttanung k lng po ung poste k ung dogtungan po s beam po..kc ung lagpas lng ako ng 50cm po s slab k..safe po b ung s s ppuntang second floor po..bli pang 3story po un.

Ayw k kc magputol n bakal s gitna ng ground floor k kc ang dami nassayng n bakal.tpos gusto muna snang matapos ung first floor k.sna matulongaun nio po ako.slmat po

[@jsdesign_engineeringtv3633]

I suggest gamitan nyo ng chemical bolt drill at least 200mm for each vertical bar. Thanks

[@joselitocancino3758]

Tali tali lng wires po at 1m ung pang splice k po sir safe lng po b un?

@@joselitocancino3758 kung may perimeter walls naman, sa tingin ko hindi na mag vibrate ang column pipigilin sya ng walls
