Ngayon ko lng napanuod ito. Mas weak sa short side ng building sa lateral movement dahil sa posisyon ng shear wall. Dapat magkaroon din ng structural analysis ang short side for assurance.
Very clear explanation sir. Sana makapagdesign kayo ng pure shear wall para s residential bec ayaw tlga ng mga architect n may mga nosing due to columns and beams. Hehe. Thanks a lot sir
Sir thank you po sa na share nyo na tutorial regarding shear wall, may question lang po ako, pwede po ba sa isang building na Dina mag lagay ng column ang beams kung shear wall ang gagamitin sa buong building( exterior and interior walls)?
Columns and shearwalls are both considered vertical elements. They have different functions and purposes. For me it would be better if both of these two elements are present in a structural framing system. Thanks
Sir pwedeng share mo yung excel package, Thanks and God bless. Bale yung shear wall independent design sa structure ng building ( Columns, beams & slabs)
mga sir kapag po ba ang shearwall is core type pareho lang din po ng process dito yung lw po kabuuan na length lang core shear wall, may boundary element po kasi
Ang vertical bars po dapat ay ginagamit to resist axial force and bending moment while the horizontal bars are used to resist shear forces. Like sa column, di mo naman idedesign sir ang vertical bars base sa shear force. Bakit mo gagamitin sir ang vertical bars to resist Vnet?
You have a point. But columns are point vertical element, that is why vertical bars are solely designed to resist vertical and occasional bending loads. Shearwall is multi task plane element, it is vertical because it is designed to resist both horizontal and vertical forces. Therefore, both bar direction direction should be designed in shear and axial. Thank you for your comment
Applicable to concrete and steel: 1.2D+1.6L 1.2D+1.0W+0.5Lr 1.2D+1.0E+0.5Lr 0.9D+1.0W 0.9D+1.0E There is more it depends on your lateral condition such as presence of soil or water pressure. I hope that helps. Thanks
Yes ofcourse pwede yan sa resi. Although naging tradition yan sa high rise because of elevator and staircase. Wala naman minimum length depende yan sa diskarte ng designer. Thanks for watching!
Sir Good Day! Sobrang informative po ng videos ninyo. Thank you po. Question ko lang po sir bakit po ang orientation ng Shearwall at application ng Base Shear ay towards Strong Axis and not Weak Axis ng Structure? More power sir!
New subscriber. If my base concrete structure until Retail L3 is seismic, can I have my upper frame in steel frame designed as static only since my below structure is already seismic? Or should I still design it in dynamic? Thank you
@@cebutravels Whether Dynamic or Static analysys is depend on the designer. What is important is you assign design base shear on that level separating concrete and steel.
Sir saan po ba kayo naka base, gusto ko po sana mag consult sa inyo personally regarging construction of 5 - storey residential building, gusto po kasi shear wall lahat ang gagamitin ko sa construction.
Sir tanong ko lang sa structural design nieed ba talaga yung both wind load at earthquake load e combine sa buildings? Pwede rin ba earthquake load nalang at e neglect yung wind load?
As much as possible we need to plug-in both lateral loads so we can use all the load combination from the code. Kung minsan hindi naman nag go govern especially on low rise structure but that is ok. Thanks
Correct, but it still good to know the basic in case you are in doubt if the computer is giving us the right output That is why there is engineer, because they knew the theory and not fully dependent on softwares Anyone can use a computer even not engineers, but if we plug a wrong data we'll definitely get a wrong answer. Thanks

sir salamat.. marami akung natutunan sa video o ninyo... salamat.. kahit hindi ko pa natapos ang civil engineering ko.. pero marami ako natutunan..
Another knowledge to all practicing Engineers. Well done Sir.
Very clear explanation sir. Sana makapagdesign kayo ng pure shear wall para s residential bec ayaw tlga ng mga architect n may mga nosing due to columns and beams. Hehe. Thanks a lot sir
Good timing sir, sagot sa assignment.👍👍👍
Very informative!! Thanks for sharing your knowledge, Sir! God bless po.
Learned a lot for today again! Thank you very much!
Galing mo sir. Sana sir yung design calculation din po ng shearwall/elevator corewall footing design sir. Thank you po
Very educational and informative explanation. Keep it up sir!
sir why on the last part at SW3, you didn't divided the Vb3 by 6 just like Vb2?
galing tlga ni sir
Sa real-world, pinagsasama po ba ang effect ng wind at earthquake sa pagde-design ng shear walls? Although slim chance na magkasabay sila.
That is correct, that is why we need to use load combination from code to see which one shall govern. Thanks
Sir elevator footing design po sana maisama niyo maituro. Thank you po
👍

gOOD mORNING siR. Very Nice Interpretation...SIr ask ko lang po ano po ang ginagamit nyo na Load Combo pag nagdedesign kayo ng Steel Structure.
Applicable to concrete and steel:
1.2D+1.6L
1.2D+1.0W+0.5Lr
1.2D+1.0E+0.5Lr
0.9D+1.0W
0.9D+1.0E
There is more it depends on your lateral condition such as presence of soil or water pressure.
I hope that helps. Thanks
@@jsdesign_engineeringtv3633 Thank you po Sir...
Good day sir, how to get the values in the second to the last column, the design beam shear in the excel file? Thank you
Sir good day. Bakit sa weight na structure hindi sinali ang columns?? Tnx po
Applicable po ba sir ang shear wall sa residential? Ilan po ang minimum length ng shear wall pag sa residential? THANK YOU!
Yes ofcourse pwede yan sa resi. Although naging tradition yan sa high rise because of elevator and staircase.
Wala naman minimum length depende yan sa diskarte ng designer. Thanks for watching!
Sir Good Day! Sobrang informative po ng videos ninyo. Thank you po. Question ko lang po sir bakit po ang orientation ng Shearwall at application ng Base Shear ay towards Strong Axis and not Weak Axis ng Structure? More power sir!
Actually dapat check natin both axis, same approach din
Masyado na mahaba presentation sir kung ipapakita ko yung isang direction.
Thanks for watching
Hi sir, pa request naman po next topic, design of underground water tank with chambers. Para macountercheck ko lang sir result ng staad.
Salamat po
New subscriber. If my base concrete structure until Retail L3 is seismic, can I have my upper frame in steel frame designed as static only since my below structure is already seismic?
Or should I still design it in dynamic? Thank you
It is possible. But you need to treat your connection of steel to concrete as pinned. That means these connections dont resist moment. Thanks

What is important is you assign design base shear on that level separating concrete and steel.
Hello po sir, Sir ask ko lang po kung anung codes sa NSCP2015 kau nga base?
Sir saan po ba kayo naka base, gusto ko po sana mag consult sa inyo personally regarging construction of 5 - storey residential building, gusto po kasi shear wall lahat ang gagamitin ko sa construction.
Send me pm on jsdesign fb page. Thanks
Sir Yung thickness Ng shearwall paaano nakuha

@@jsdesign_engineeringtv3633 Maraming salamat sir .More power!
Need to check both load combination..mostly sa mga high rise 60 floor and up..wind load ma nag-go govern..
@@bienramos7587 thank you sir.Pero kung like 2 storey lang sir pwedeng earthquake load lang e consider kung mataas sya kaysa wind load?
Yes Kung 2 storey lang governing load ang Eqk..
Sir pano malaman kung di na need ng shearwall. Lalo kung 3-5storey lang. Or residential house lang. Tnx
Normally sa low rise building hindi kailangan, kung meron elevator core pwede mo gamitin as shearwall (dual function). Thanks
Sir good day! tanong ko lang po kung kailangan pa ba ng lateral ties sa shearwall to resist shear?
I actually provide horizontal bars in my presentation, please watch until the end of the video so you can see the complete rebar detailing. Thanks
sir paano po i analyze pag irregular shape ang building?
In that case, you will have different lateral force for each grid line because of the variable tributary area. Thanks
@@jsdesign_engineeringtv3633 ano po yung tinutukoy nyong grid line sir?
Pabalik na tayo nakalimutan na 1990 pa up grade na ngayon noon manual ngayon puro software.
Correct, but it still good to know the basic in case you are in doubt if the computer is giving us the right output
