Doubly Reinforced Beam USD (NSCP 2015) TAGALOG - Problem No. 1 (Part 1 of 2) 

0.004 and 0.005 rin ang gamit ko nung college. Actually marami ring usapan dyan kung ano ang gagamitin e. Sinunod ko na lang yung inistate mismo sa NSCP

@@CivilEngineerMachan Nakita ko din sa Vid ni Jaydee Lucero ehh, magmatter ba master?

According to NSCP

Kung iintindihin natin yung sinabi sa structural code: Pu is the axial capacity of the member (beam) and if it is less than 0.10f'cAg, pwede natin sabihin na ina-analyze natin yung beam na mas maliit pa sa 10% ng axial force ng concrete yung expected na kaya nyang buhatin. And since walang sinabi sa problem na subjected ung beam natin sa axial force, na-satisfy na nya yung condition na yan. Kumbaga ang gusto sabihin ni NSCP, yan ang analysis sa beams na nineneglect na ang axial force. PS: The main and common purpose of beams is to carry flexural bending stress of a structure; and columns are to carry axial loads. Thank you for the question! :)

@@CivilEngineerMachan Thank you sa explanation Sir..ang gamit kasi namin noong review ay 0.005 para makuha As max for singly.

@@markadduru5011 actually nung college ako 0.005 and 0.004 namin chinecheck pero hindi ko pa nabasa nun ung actual statement ni NSCP.

@@CivilEngineerMachanThank you po Sir.

Ang pwedeng mga ibigay sayo na given pag walang snabi na effective depth: total depth, steel cover, concrete cover, clear concrete, diameter of stirrups. Pag meron yan macocompute na eff depth

@@CivilEngineerMachan salamat po. Parang singly lang pala. Pag hindi naman uniform ang distribution ng bars? Like 1st layer is 4 and 2nd layer is 2. Then I'll use the Varignon's theorem centroid.

Given dapat sya. Try to check baka grade ung pagkasabi sa problem
