hello, bakit po after ko icheck kung srb or drb after comapring AsMax to AsActual ang lumabas ayy isa lng po syang SRB, mas mababa po si AsAct kay AsMax, pa correct naman po ako salamat pooo

@davecristianconejos870 2 месяца назад

same po.

Isn't tension bars needs to yield first before compression bars can?.... I thought the creteria should to be to assume; tension bars yield and compression bars don't yield and to obtain strains of compression steel from strain-similarity diagram

@torresoliverlander4546 2 года назад

Yeah. I guess this is for investigation or solving purposes only. In reality, Tension steel must yield in DRB. as it is in principle that as As+=a+ and (a) has limit that is why we need Cs.. puting many steel in tension is useless as it will become compression controlled.. x for economy x for Strength

@J4GDaily_jes Год назад

Not always tension bar yields. Compression bars sometimes need due to concrete is not enough to resist compression force.

Hello po, I know this is late pero meron akung question regarding sa pagdetermine if ang paganalysis natin is either DRB o SRB. Paanu namin malaman if ever yung question ay i analyze namin is DRB o SRB ???

@pigmaluchnnl8765 4 месяца назад

Kapag Analysis if As>Asmax, DRB Kapag Design if Mu>Mumax, DRB

Lods, always ba na nasa baba ang tension

@bellebeau6273 Год назад

Hi po how to Calculate the balanced steel ratio if the beam is singly reinforced.?

@al-rhajeedjawatan4681 2 года назад

posible po ba na magyield ang T1 and di magyield ang T2?o di kaya di magyield ang T1 and magyield ang T2? or kung dapat ba sabay sila pareho na once magyield ang Tension bar(T1+T2) yield sila pareho (T1 and T2) or kung hindi magyiled ay di rin sila magyield pareho(T1 and T2).

@al-rhajeedjawatan4681 2 года назад

dapat po ba na once magyield sa tension bars yung T1 and T2 ay sabay din magyield?o di kaya kung di magyield sa tension bars ay sabay din sila di magyield pareho.?or posible na magyield isa sa kanila (T1 or T2)at di magyield ang isa(T1 or T2)

@J4GDaily_jes Год назад

Possible na di magsabay mag yield ang Tension Bars. Of thats the case, una mag yield si T2 (yong extreme bars). Makikita mo kung mag summation of Moment kasi mahaba ang moment arm ni T2, kasi mas stress siya kesa kay T1.

Thank you sir❤️

Thank you for watching! Please check upcoming tutorials :)

@edbo9119 2 года назад

Sir, i would just like to clarify that the beam is designed or analyzed as doubly reinforced if/when the actual steel ratio exceeds the maximum, am I right? In your solution, I didn't see you compare the steel ratios. Just asking. Thanks

@edbo9119 2 года назад

In your 2nd example, how can you fit 10-28mm (1 layer) in a 320 mm width of beam?

@edbo9119 2 года назад

@ time stamp 11:28, you mentioned fs' does not yield when it it greater than fy, then @ 13:42 where fs' is the same, you mentioned it is ok. Please clarify.

@J4GDaily_jes Год назад

@@edbo9119 Tignan mo po mabuti ang figure, 2 layers nga eh. Bat mo pa pagkasyahin sa 1layer ang 10pcs?

@J4GDaily_jes Год назад

@@edbo9119 Okay naman ang explanation niya. Iba ang value ng fs' @ 11:28 and 13:42.
