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

[@Lopz-d4k]

parang gusto kung makita mag publish yung kippap ng rcd book😌🔥

[@Ikacakes]

Seconding this sana may book na NSCP 2015 with past boards 😭 puro 2010 nahahanap ko

Hello, bat po 3/7 ginamit sa rho max instead na 3/8 since TC?

[@ribencarating6783]

I tried c po in substituting for finding fs', in calculating it, it still did not exceed 420. why is this po?

[@ribencarating6783]

tas if gamitin nating c=95.41 po, nagyield naman po siya sa tension side po at hindi nag yield sa compression side po

[@bimini8425]

hoping you make episodes 4-11 of es 101 series available again!!! very helpful po for someone taking es 101 right now hehe

[@mewsicman9541]

32:16 Sir pag ni round up sa 2 bars yyng comp steel, hindi ba magiging over-reinforced yung beam?

[@chesterjapson1744]

Salamat idol gawa ka pa Po more tutorial Pa sa RCD . T-beams , slab , foundation ,

[@_aysak]

hindi po ba ang C sa Problem 1 (analysis) is 154.5214?

[@KippapEducation]

May we know saang step naiba solution niyo?

[@nhojcapili8735]

@@KippapEducation sir 154.521 po nalabas for C. Yung step po after ma check if steel yields Cc + Cs = T. Hindi po nalabas 128.6727

[@KippapEducation]

⁠@@nhojcapili8735 i tried it again, my full equation was
0.85(28)(0.85x)(350)+512pi*600((x-70)/x) = 1024pi*420
Ang lumabas sa calcu ay 128.67

[@nhojcapili8735]

@@KippapEducation ahhh okay na po sir salamat

[@michaelpedrito9837]

yung sa example 1 po, bakit po ang phi ay 0.9 kung ang tension bars ay nag yield pero ang compression bars ay hindi nag yield? Always po ba naka base sa tension bars ang reduction factor sa DRB?

[@KippapEducation]

Yes, sa tension bars nakadepende ang phi

[@confeccti7100]

hello, di po ba opposite yung answers sa number 2 and 3 sa design?

[@KippapEducation]

Hello! Can you elaborate?

[@confeccti7100]

@@KippapEducation sa 28:50 po, di po ba yan yung sagot sa steel area sa tension? sabi niyo po kasi yan yung sagot sa 2nd question, wherein yung tanong is steel area for compression. nalito lang po ako

[@KippapEducation]

@@confeccti7100 ah yup. Nalito lang ako sa order ng questions haha, pero the compression and tension steel area are indicated naman sa pagsolve ko

[@juancho_ru]

Nays 1 sir 😇

[@UzumakiNaruto-d6b]

Hindi po ba kasama sa pag compute ng moment capacity ang reduction factor (phi)?

[@KippapEducation]

Mentioned na sa both problems na tension-controlled (phi = 0.9)

[@datukingmandi4858]

Boss, kung ang gamitin pong rho-max is pang T.C? Pwede po?

[@KippapEducation]

For board exam mas maganda gamitin ang Rho Max na 3/8 para ma-ensure na tension controlled

[@pablojuan8896]

Saan niyo po nakuha yunhlg value ng w=10?

[@JoshuaCedilla]

Nasa problem po, Yan Yung uniform deadload

[@pablojuan8896]

@@JoshuaCedilla salamat po Engr pag actual designing po ba lalo po pag may contract project 10kn/m po kadalasan ang value ng w? salamat po sa sagot sir🤗

[@Grade11STEM-zs8vc]

Hi Grade 11 student here, learning this para matop ko board in the future 🤩

[@thecompanypolicy3934]

😂

[@Ikacakes]

I think G11 is the perfect time to master the foundational courses rather than design agad haha. Very impt ang basics sa engineering, mas nagiging intuitive ang formulas sayo in the long-term,, maybe look for statics muna before reinforced concrete design?

[@zackfair2]

Nasaan ang mga answr sa question number 1 at 2 sa first situation?

[@KippapEducation]

Depth of compression block is 0.85(128.67). Moment capacity is at 15:20

[@markkellybalgos7398]

Sir. What if negative po Yung excess moment?

[@KippapEducation]

That means hindi siya excess and baka singly reinforced beam lang ang analysis

[@Man-wh1pq]

tension controlled po lahat sa board exam?

[@KippapEducation]

For design problems, yes tension controlled dapat. If analysis naman, you can do checks (strain of steel > 0.005) para malaman if tension controlled yung section.
