CE Board Exam Review: Singly-Reinforced Concrete Beams (NSCP 2015)

[@jasminerae5154]

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!

[@carltolentino2044]

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.

[@boxandshades412]

Just to clarify lang po, sa cantilever ba ibig mo sabihin? Thanks.

[@allyce06]

Magaling talaga magturo yung nasa board exam review compare sa school, baguhin na dapat sistema Ng pagtuturo sa school

[@karljohnhelbiro9205]

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😊

[@karljohnhelbiro9205]

Sana po Engr. Villafuerte maka post kayo ng video on how to analyze and design for Doubly Reinforced Concrete Beam😊 Tiyak malaking tulong po.

[@geraldagas4494]

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)?

[@KippapEducation]

Hello! It's a correction. Pero it doesn't matter naman since hindi umabot yung rho sa rho max.

[@pablojuan8896]

Sir pano niyo po nakuha yung value na rho max=0.0247 bali po kasi ang napapalabas ko is 0.018? salamat po sa sagot

[@kimberlynneuera8427]

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?

[@Hezekiah7777zjckfka]

They will add strength

[@mr.d3916]

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.

[@peejaycalunsag6716]

Pwede po ba na iassume ko ang phi= 0.65 sa pagkuha nang Rn? Tapos saan po malalaman na mali yung assumption na yun?

[@thinkaboutrainbow]

Hi po ask po . Pano po nakuha yong a na 133.14 sa 14:47 po? Yong sa C=T ? Paki sagot po

[@tamarionchettymae4497]

Sir, yung ginamit ko po is pmax = ( 0.85 fc'/fy) B1(4/7)(dt/d) at yung answer ko po is = 0.0239

[@tamarionchettymae4497]

Kasi diba po yung given fc' is 24 MPa minus 28 MPa then divide it to 7MPa.

hello help. nag calcu po kasi ako sa pmax. (.85(24)/415)(.85)(3/7) bakit equals 0.0179 naman nalabas

[@KippapEducation]

Yup it’s a minor correction pero it doesn’t affect the final answer naman since pang-compare lang siya 🙂

[@tinaursua5158]

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

[@KippapEducation]

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

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.

[@villapusa4825]

Kapag mag-aanalyze ka, 3/7 gamitin mo Kapag mag-dedesign ka, 3/8 gamitin mo

@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

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)?

[@derickjeremyramos3104]

Sir sa Pmax (analysis), bakit 3/7 hindi 3/8?

[@KippapEducation]

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.

[@derickjeremyramos3104]

@@KippapEducation Bale sa design gagamitin yung 3/8 sir no? Hindi po sa analysis.
