parang gusto kung makita mag publish yung kippap ng rcd book😌🔥
Hello, bat po 3/7 ginamit sa rho max instead na 3/8 since TC?
32:16 Sir pag ni round up sa 2 bars yyng comp steel, hindi ba magiging over-reinforced yung beam?
Nays 1 sir 😇
I tried c po in substituting for finding fs', in calculating it, it still did not exceed 420. why is this po?

tas if gamitin nating c=95.41 po, nagyield naman po siya sa tension side po at hindi nag yield sa compression side po
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)
Boss, kung ang gamitin pong rho-max is pang T.C? Pwede po?

For board exam mas maganda gamitin ang Rho Max na 3/8 para ma-ensure na tension controlled
hoping you make episodes 4-11 of es 101 series available again!!! very helpful po for someone taking es 101 right now hehe
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?

Yes, sa tension bars nakadepende ang phi
tension controlled po lahat sa board exam?

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.

Salamat idol gawa ka pa Po more tutorial Pa sa RCD . T-beams , slab , foundation ,
Sir. What if negative po Yung excess moment?
@KippapEducation

That means hindi siya excess and baka singly reinforced beam lang ang analysis
Saan niyo po nakuha yunhlg value ng w=10?
