Thanks

Naging professor po sana kita during my undergrad.

Thanks

Salamat po

Agree!

Tama po, check lang natin kung hindi mabubutas kasi may mga Steeldeck na manipis ang gauge, pag nabutas huwag natin ituloy ilagay nyo nalang yung bars along bottom of flute kahit every other flute para hindi madyado magastos, use 10mm, hook and tie at one end (far-most side of beam). Also important din yung extra bars at every top of support yung sinabi ko sa video na extended at L/4 each side of interior beams. Thanks

Thanks

Rudy Fernando personally, i think spacer is required for the reason na binaggit po ninyo..

Thanks sir

hello po pwede po malaman kung san niyo po nabasa or nalaman yung recommendation nayan? for academic purposes lang po, salamat sir

Ang direction po ng steel deck kung bakit along the shorter dimension is because steel decking follows the principle of one way slab where main bars are placed along the shorter direction

@@fidelgolla7539 tama, kapag nasa shorter span yung main bar ay ang strength nito ay maganda na makapaghold ng other bars.

Agree thanks

Ang ma ipapayo ko po, bilhin ninyo yung kung saan kayo makakatipid. Ang importante dyan kumausap kayo ng installer who has long years of experience in installing steel decks, dapat alam nila kung paano ilalagay yung mga extra bars na hindi masyadong marami pero nasa tamang location

Mas maganda kung may 20mm gap from steeldeck

Check po ninyo sa mga brochures ng steeldeck meron sila ready-made na table model and design gauge for a given spacing and loads. You dont need to design. Yan advise po natin sa video is to guide those who are using it improperly but if anyone who will follow the brochures from the supplier you dont have to provide those bars that I mentioned in the video. Also advisable lang po yan sa mga span more than 3meters. Thanks

@@jsdesign_engineeringtv3633 Engr. Sana po nabanggit nyo to sa video nuh. I thought applicable sa lahat ng span. Namention rin lang naman ang mga L/3 to L/8, sa RCC din po ba di na inaapplu ang L/3 to L/8 pag less than 2m span ng beam?

Yes I suggest to hook at least 50mm and reach the farthest side of the beam. Thanks

Hindi na po need yung bakal sa baba kung meron ng bar na patayo, enough na yan para kumapit yung steeldeck sa concrete (option 1 and 2 yan), but yung extra bar sa top support kailangan talaga. Make sure lang po na applyan nyo ng epoxy primer yung mga welding "spots" pati dun sa ilalim ng deck para hindi mag simula ang rust. Salamat

Kung napili nyo naman yung bakal sa baba, itali lang ng tie wire no need to weld, kahit every other flute para hindi masyado magastos, 10mm lang yung size. Advisable po yan for a span of 3meters or more. Kung may question pa tanong lang po kayo. Salamat

Videos lang meron ako sir. Thanks

May mga designer hindi naglalagay sa discontinuous-end, but ako nag lalagay, L/5 space at 300 same size sa intermediate support. Thanks

Practical computation nyan, dapat alam nyo kung ilan ang tao na gagawa, how many days gagawin especially yung steeldeck installation. Then times rate per day. Roughly mag karoon kayo ng idea, syempre yung rate ng tao varies depende sa skill, at kalakaran sa lugar ninyo. Thanks

Sa tingin ko midspan pwede hindi na for 3m or less, but top bar at support mag provide kayo at least 30cm o.c. spacing

Monolithic pouring naman I suggest sa ilalim ng beam top bars yung slab rebars. Thanks

ganto din yung idea na naiisp ko ang shear studs ai for Steel Beam hindi mismo sa steel deck

Minimum of 1 bar every deck flute, thickness minimum of 4 inches.

@@jsdesign_engineeringtv3633 salamat po sa reply engr.

Normally tack weld or spot weld lang po, then pour na ng concrete slab. Thanks

@@jsdesign_engineeringtv3633 pwede po bang ipatong lang at hindi na iweld? thank you!

Wala akong makitang problem dyan, pwede naman

Parehas din po ng conventional concrete slab, after 1week pwede na mag bawas ng support mga 50percent, iwasan lang natin mag lagay ng stockpile especially sa midspan for at least 3weeks

Yes, that is absolutely the purpose of it. However, there are no clear consensus about the effectivity of such features especially on generic or unbranded products. As a designer we always treat every condition in a worst -case scenario, and my video explains it in general about "how to properly reinforce" in case those things happen. FYI

In my experience pag residential type ang loadings wala pa ako nakita nag collapse. Thanks

Kung steeldeck, hindi kailangang maging both ways ang bakal, normally one way lang ang application nyan.

@@jsdesign_engineeringtv3633 ganun po b.pero matibay po b?wla kc ako alm jn boss hehe

Matibay po yan

@@jsdesign_engineeringtv3633 slamat po engr..ngaun panatag n loob k ..

As far as I know steeldeck are normally treat as one-way slab because of its corrugation, I cant figureout how some are treating it as two-way, except they dont know how to use it properly

@@jsdesign_engineeringtv3633 in that case, they used perforated steel deck.

I suggest skip mo nalang ang bakal sa lahat ng may electrical conduit para hindi congested walang kaso yan mas importante kasi yung extra top bar sa support

@@jsdesign_engineeringtv3633 ok po engineer. salamat

Wala naman issue kahit naka dikit kasi permanent structure ang steeldeck, ok din naman kung lagyan ng spacer but not more than 25mm. Thanks

Minimum 100mm from top of flute, so it depends on deck profile, ex. If flute depth is 20mm total depth will be 120mm. I hope that answers your question. Thanks

Maliit naman ang chances ng corrosion especially kung interior slab (not directly expose to weather). Kasi ganun din naman gingawa ng marami sa regular rebar / meshwire they place directly on top the steeldeck flute( naka dikit din). But pwede rin naman maglagay ng concrete spacer to avoid physical contact. Sa welding spots, normally we apply epoxy primer only on weld points. Thanks

One practical option, is provide intermediate beam then cast conventional rc slab. Thanks

Correct po, dual function ang steeldeck kaya naging popular sa floor construction, but ang sinasabi po natin sa video kung masisiguro natin yung adhesion between concrete and steeldeck walang problema, kaya isa sa mga paraan nag lalagay tayo ng shear studs like we mentioned in our video. But pwede rin nama every other flute ang dowels para may room for utilities. Salamat po sa comment

Yes, but carefull on locations especially where bending is maximum. However, it is better if you anticipate hole locations before pouring in order to provide adequate dowels around it. Thanks

@@jsdesign_engineeringtv3633 maraming salamat po

I suggest skip nyo na yung extra bar sa portion ng electrical junction box, that's fine

kalimitan expose na yon electrical, water line or yon tinatawag na mefps pagka steeldeck ang ginagamit. sa ilalim lang ng slab naka hanger.

pagka bahay lang naman pwde siya iabang at butasin na lang. yon usual nag pag install ng mga junction box na hindi pa uso ang steeldeck. naka abang lang sa porma ng floor.

Masasayang lang yung rebars mo sa other direction. Steeldeck is designed for oneway slab application

Yes, it should always treat it as one-way because of its flute. Thanks

@@jsdesign_engineeringtv3633 salamat den sir~ nag subscribe na pala ako sa channel mo, nice content po, more blessing po ulet Papanuorin ko ulet ibang video niyo po, Hope you'll answer some of my questions next time (maraming thank you)

Hindi po need ang welding sa straight bars. Thanks

@@jsdesign_engineeringtv3633 ok lang po ba design na: bottom bars, 10 mm per pan. Top bars, 10 mm 300mm oc transverse bars. 12mm 900mm oc, 225 mm oc on L/4 along the deck span

@@rapskidooo saan mo gagamitin yung 900mm OC? Yung 225mm oc na top bars ok lang

@@jsdesign_engineeringtv3633 bali yung 225mm top bars eh yun yung extra bar na nasa L/4. tapos yung 900mm oc yung continuous na bar

I suggest at least 300mm oc 10mm dia

Pwede, marami gumagawa nyan. Monolithic din yung buhos ng deck slab sa concrete beam. Thanks

Pero sir yung tapos na nabuhosan lahat o buong beam bali ,pinatong nalang yong steel deck after pwede po ba yon? Parang kahoy pinatong nalang sa, isang dahoy na beam, pwede ba yon sa steel deck?

@@clifordlanojan953 Still possible, just roughen top surface no need to expose rebar, then place your decking on top existing beam (at least 2" sitting). I suggest provide stud(16mm dowel) drilled @ 600mm apart epoxied for proper adhesion between old and new concrete. I hope that helps. Thanks

Thanks engr. Salamats talaga, kahit 2 am na sinagot mo parin ako, another kaalaman po sir, 🙏🙏🙏 still watching sa mga videos mo Sir, mas maganda ang pagka explain mo, maraming salamats po ❤

Halo engr. Hopefully ma sagot nyo ako ulit, for rebar mattingbsa steel deck, pwede po bah, 0.30m sa ilalim 12mm dia. x 0.15 mm dia. sa itaas ? Matibay po bah to?

Heat transfer cannot be prevented whatever material we use especially in tropical countries like Philippines. The solution is to place an insulation underneath if it really needed. Thanks

@@jsdesign_engineeringtv3633 dba pwde sa ibabaw ng steel deck ilagay ang heat insulation bago buhusan sir?

@@mrroy2187 Meron gumagawa sa ibabaw but it would be very expensive and I doubt few contractors know how to do it, its a special technology. I suggest, mag lagay ka nalang ng ceiling with enough room between ceiling and steeldeck para may air-circulation. Then kung gusto mo mag lagay ka pa din ng insulation sa ibabaw ng ceiling I'm sure it will make a difference. thanks

@@jsdesign_engineeringtv3633 thank you sir

Sorry sir, I'll try to improve my audio next time. Thanks

Most of the time monolithic

Depende sa profile ng metaldeck, but normally 75mm excluding flute. If flute is shallow, say less than 20mm use 100mm concrete thickness. Thanks

Ang steeldeck po advisable lang sa oneway slab because of those corrugations. Thanks

@@jsdesign_engineeringtv3633 so kung two way slab ang mas maraming slab sa building. Better po ba na wag na mag steel deck?

Yes you are right. Thanks

Sir, bigla lang po ako naguluhan.. So, kapag based sa dimension ng slab is two-way slab po, hindi po ba pwede gamitin ang steel deck? Sana po masagot niyo ang gumugulo sa isip ko po kasi lahat ng nakikita ko nagco-construct is naka steel deck lahat kahit two-way.
