Super thank you for this po. Super hirap po ng ol class and di ko sya gets sa turo ng instructor namin dahil madalas lag dahil internet, so glad nakita ko po videos mo, nakatulong. More videos po! ❤️ Aspiring future engineers here!
simply at parang naka summary lahat ng sinaaabih nyo Sir, bawat bigkas nyo noted ko po, Maraming salamat po kung may time po sana kayo coverage nyo narin po yung topic DOUBLE R.C at T - Beam
Grabe ka Engr. Villafuerte, ang galing ng pagka explain mo sa SRB. Napaka daling intindihan, na explain mo talaga ng maayos yung concepts behind it and ang mga process sa pag analyze at pag design ng SRB. Thank you so much po, Engr. Villafuerte😊
d is measured from extreme compression fiber to the centroid of tension bar. In case the beam will be subjected to a clockwise bending or a sad beam, then the topmost will be subjected to tension. So, not all the time d is from the topmost of beam.
Sir thank you dito, napaka galing po ng explanation. Yung sa una may pa intro muna para ma imagined ng viewer yung tatalakayin mo tapos may steps para susundan na lang ng student yung process. More videos pa po sir sa RCD. Ty😘
Hi Sir, tanong ko lang po. Paano po nakuha yung sa (RHO)maximum na 0.0247? ginamit ko po yung formula at substitute lang po pero yung sa calculator ko is 0.01791 ang dt/d po di ba ay (1)?
If additional reinforcing bars are placed only in the compression side of a reinforced concrete beam, will they add significantly to the beam's flexural strength?
It depends on the ductility of the beam which is based on the provided reinforcement. If the beam is ductile enough, let us say the rho actual is between rho min and 50% of rho max - the compression reinforcement has no significant effect on the nominal capacity. Otherwise, you will just see the significant effect when your rho actual is near equal to rho max.
Tanong lang sa problem 2 diba Yung Mu ata na nagamit mali uniform load palang yun. So need pa mahanap Yung max moment given Yung uniform load na galing sa load combo. Pero Yung di given if Yung beam is simply supported or ano. Kaya di masosolve ano yung Mu
Sir about po sa analysis, aside from comparing p and pmax, may other way pa po ba to determine if singly or doubly rein.? If ever po kasi na p>pbal (steel do not yield), sympre po p>pmax din po. Analyze as doubly po ba or analyze as singly (steel do not yield)?
Sir. Sana mag add po kayo ng vid like this prob po for SRB. "Design a rectangular beam for a 6m simple span to support a deadload of 29kN/m (including its estimated beam weight) and live load of 44kN/m. Use rho max, fc'=27.6 MPa and fy=276 MPa. Or can anybody help me w/this prob. Coz i saw one, but with touch of NSCP 2001😔 (need NSCP 2015)
Good day Sir, ano po ba talaga ang dapat gamitin pag kukuha ng rho max kasi may 0.004 ang imumultiple ay (3/7) tapos may 0.005 ang imumultiple ay (3/8)... May specific na rason po ba kung kailan sila dapat gamitin?
sa problem 2 nman sir yung factor na gamit mo sa Rn is 0.9. pero nung kinuha mo yung rho max, 3/7 (0.004) yung ginamit mo, nasa transition naman yun sir. sir d ko macompose ng maayos yung tanong ko, pero malabo kasi sakin kung alin sa dalawa ang gagamitin, 3/7 o 3/8 ba.
Hello! I definitely recommend na you enroll in a review center kasi investment mo rin yun sa sarili mo :) may review program kami for May 2021 if gusto mo makahabol.
Same lang ang makukuha, iba lang ang order ng operations. I prefer na icompute muna ang design load using 1.2DL and 1.6LL then compute yung ultimate moment
@@KippapEducation yes sir, since i,resolve your examples just to compare..i got pmax is equal to 0.0179..d koh alam kong tama bah or kulang yong formula na n,input koh..salamat sir..Godbless
Because 3/7 would give a steel strain of 0.004, which is the minimum acceptable strain. If 3/8 ang gagamitin mo, ang corresponding steel strain would be 0.005, which is tension controlled na.

Hello sir, Gillesania po ba nanggaling yung mga example problems na nasolved?
Hello po, what to do if Wsdl and Pdl only ang given?
Thank you sir! pano po pag doubly reinforced beam ??
Napakahusay ng paliwanag
Idol ano po name ng books sa structural design (concrete)
Power!
Yong Pmin po ba na formula pinakita niyo is iba rin pag sa ENGLISH UNIT? Kasi SI yong mga values sa problem.
Sir pano po nakuha yung rho max na 0.024? Thanks
May doubly reinforced ba kayung. Video sir?
Sir pag nscp 2001 nman gimamit sa design mag aasume parin ba ng tension controlled?

Hello! It's a correction. Pero it doesn't matter naman since hindi umabot yung rho sa rho max.
If additional reinforcing bars are placed only in the compression side of a reinforced concrete beam, will they add significantly to the beam's flexural strength?
They will add strength
It depends on the ductility of the beam which is based on the provided reinforcement. If the beam is ductile enough, let us say the rho actual is between rho min and 50% of rho max - the compression reinforcement has no significant effect on the nominal capacity. Otherwise, you will just see the significant effect when your rho actual is near equal to rho max.
Pwede po ba na iassume ko ang phi= 0.65 sa pagkuha nang Rn? Tapos saan po malalaman na mali yung assumption na yun?
Hoping for more vids regarding RCD and Steel Design.🙏💖

Hi sir. Is your virtual classes still open like on july to october?
We are about to open enrollment for the November 2021 board exam. Please wait for announcements.
I like your presentation. But I had a lot to back to.
SIR SIR SIR bakit 0.004 gamit mo sa pagsolve ng rho max, tapos yung nakuha mong strain na 0.00753 kinompare mo naman sa 0.005
Sir ang value ng pmax ay 0.017 correction lang po
Sir, ano pong nakuha nyong value sa p?
Same po tayo nakuha value ng pmax 0.017
Same po tayo ng nakuha 0.017.
Same

Up
make a video about doubly reinforced :D please huehue
Sir doubly naman po
@Kippap Education Sir, paano po kung ang value ng f'c ay mataas pa sa 28. Anu po ang magiging outcome ng value ng B1??
You will use linear interpolation for fc’ greater than 28. Pag greater then 56 naman, fc’ is always 0.65
Engr. statistics naman po😁
normal distribution po..
Sir 0.0179 ang lumabas na rho max sa computation ko hindi po 0.0247, paki check ng formula or computation. Thanks!

The given values (20 and 35 are already moments kasi kN-m ang units nila) distributed loads have a unit of kN/m

Analyzed as doubly reinforced na pag ganyan.

Hello! I definitely recommend na you enroll in a review center kasi investment mo rin yun sa sarili mo :) may review program kami for May 2021 if gusto mo makahabol.
Sir, yung ginamit ko po is pmax = ( 0.85 fc'/fy) B1(4/7)(dt/d)
at yung answer ko po is = 0.0239
Kasi diba po yung given fc' is 24 MPa minus 28 MPa then divide it to 7MPa.
@@tamarionchettymae4497 isosolve lang po ang B if ang fc' is greater than 28 MPa.
new subscriber po galing niyo po magturo baka DRB din po ituro niyo din thankyou
hello help. nag calcu po kasi ako sa pmax. (.85(24)/415)(.85)(3/7) bakit equals 0.0179 naman nalabas
Yup it’s a minor correction pero it doesn’t affect the final answer naman since pang-compare lang siya 🙂
ahh okay thank you
@@KippapEducation pero bakit po 3/7 diba po dapat 4/7?
Masasabi ko..ito yung katuro na hindi madamot sa concepts. I think i will enroll sa kipapp.
Thank you for this! It means a lot 😀
Sir bat po hindi muna niconvert yung DL at LL sa MD at ML para makuha yung Mu?
Same lang ang makukuha, iba lang ang order ng operations. I prefer na icompute muna ang design load using 1.2DL and 1.6LL then compute yung ultimate moment
@@KippapEducation ah okay po. Salamat sir 😊
Pwede pa po ba humabol for review para sa May 2021 board exam?
Yes pwede pa, please message our page for details.

Sir ask lng po saan nanggaling yung 600 sa video @15:25 fs=600(d-c)/c
Thanks in advance sir.
Modulus of elasticity ng steel * useful strain ng concrete
200,000 MPa * 0.003
Thanks sir! God bless.
sir paano niyo po nakuha yung a= 133.14 ?
from equation C=T, a yung missing kaya shift solve lang
Parehas po ba talaga sir laman ng nscp 2010 at 2015?
May ilang parts na magkaiba. Pero sa singly reinforced beams, halos parehas lang
sir paano po malalaman kung ano pong diameter of bars po gagamitin sa no. of bars?
Given na dapat yung diameter if pinapahanap yung number of bars. Usually ang pagkakatanong is “How many 20 mm diameter bars are needed?”
salamat po
@@KippapEducation
Engr, paano po ma determine if ang problem is Analysis or Design po?
If ang tinatanong ay maximum moment, analysis siya.
If ang tinatanong ay number of bars, design
@@KippapEducation Thank you po
Paano malaman po kung singly siya or doubly?
Goodvening sir..bakit 0.0247 yong pmax? Prob 1..
Slight error lang sa pagcompute ko, pero it shouldn’t affect the solution, ginamit lang ang p max to compare
@@KippapEducation yes sir, since i,resolve your examples just to compare..i got pmax is equal to 0.0179..d koh alam kong tama bah or kulang yong formula na n,input koh..salamat sir..Godbless
Sir sa Pmax (analysis), bakit 3/7 hindi 3/8?
Because 3/7 would give a steel strain of 0.004, which is the minimum acceptable strain.
If 3/8 ang gagamitin mo, ang corresponding steel strain would be 0.005, which is tension controlled na.
@@KippapEducation Bale sa design gagamitin yung 3/8 sir no? Hindi po sa analysis.
@@derickjeremyramos3104 yes. 3/8 ang gagamitin mo if you want to ensure na tension-controlled ang section.
@@KippapEducation thank you sir
@@KippapEducation kung minimum po yung 0.004 na strain bakit di po gamitin yung 0.005 na ideal strain para sa Pmax?
