salamat po sir sa mga videos mo. malaking tulong po lalo na sa pag refresh sa amin na may konting kalawang na sa pag dedesign.
Dadami ang subscribers nyo Sir dahil maganda at magaling kayong magpaliwanag!
Panalo sir yung explanation mo po. ❤️❤️❤️ Bug help. Wishing u more blessings and good health. Thank u po
I really appreciate your content, very helpful po. More videos like this po.
27:46 Looking forward to this topic also, about T-beams. 🙂
Engr nakaka refresh ang video mo. Salamat
Maraming salamat po. Laking tulong nito ngayon sa aming mga estudyante. Di gaano nagtuturo mga prof dahil onli r class pa rin.
Your welcome, I'll make more design related videos to come. Please share it to your classmates. Thanks
Madaming Learnings sir, Salamat sa Maliwanag na Explanation sir.
Sir May simplified Books na Po Kayo sa lahat ng Content nyo na pwedeng Bilhin..Na Pwdeng Pag aralan.....Exciting Pag aralan mga content nyo sir. Subcriber nyo ako sir.
Very clear and precise explanation. Thank u
Salamat po sa paliwanag. Ang galing.
Thank you po sir. Galing niyo po. God bless
Thanks po muli...more power po....
Malinaw pa sa liwanag thankyou engr :)
sana po Sir, sample din how to compute the shear and moment acting on the beam.
More power po and thanks for your unselfish sharing of knowledge.
4:00 I am also hoping for a separate topic for Structural Analysis, I'm sure it will be very useful to tie up the content in this video with Load Calculations.
Sure, I will try to make a video about analysis of continuous beam, please stay tune to this channel. Thanks
Sana po meron ding double reinforced beam na explanation sir, mas naiintindihan yung explanation nyo
Sir thank you so much po sobrang laking tulong. 🤗
Great lecture... More power..
Maganda yong structural analysis topic Sir.
Very informative Sir! Thank you!
sana po kayo ang Prof ko nung college
ang galing nu sir...
Tnx sa lecture sir.
Thank you sir
Baka po pwedeng load analysis, 3span na frame, paano po kumuha ng design moment and shear ng roof beams and 2nd floor beams
nice explanation sir!
Sir san po galing yung d= cube root of 130.62?
Sir can make complete sample calculation for thin walled vessel. Thank you
Complete presentation calculation of thin-walled pressure vessel.
🎉good day sir! Requesting po for catch-up plan if granted. Thanks a lot.
Sure. For the mean time, I suggest to visit my channel's playlist "Project Management". It might help a bit.
Thanks
Sir, ang T = Asfs. Ginawa niyong T = Asfy dahil ang fs naging equals fy due to balanced design? Sa balanced design, steel and concrete yields at the same time?
Sir gusto ko po sana makita mga values na ginamit mo sa DL and LL sa first part po ng video, thank you po! God bless!
We'll make one soon. Thanks
❤️
Good day sir, tanong kulang po sana if pwede po ba magamit yung mga internal forces na nakuha gamit ang portal method sa pag design ng beam?
If you can perform analysis considering the whole frame, that will give you the cheapest design result instead of treating individually.
I suggest use any 3D model analysis software then pick-up stress results for sizing of members. Thanks
Good day sir . Asked ko lang ganyan po ba kataas balue ng moment sa computation ko ng moment sa beam is 17kn/m2 lang sa dinedesign ko na 2 storey residential house
No, follow your assumptions,
mine is just an example in order to explain design procedures. Thanks
16:28 Sir I watched the video, on this part can I ask if this is also applicable to NSCP 2015?
May least minimum dimension din po ba ang beam size tulad ng sa column.?
Normally we pattern to least column dimension. Thanks
Ano po ba talaga ginagamit sa nscp 2015, 1.2DL + 1.6LL or ung sainyo po?
Yes the one you mentioned is the right one. Thanks
Good day, sir sa load calculation, pwede po b nmen I-apply yung sa tributary, same approach sa column at footing design. .. SALAMAT sir, God Bless po.
Yes for sure, try it that will make your calculation faster. Thanks
Sir bakit po sa factored load ang ginamit niyo po is 1.4DL+1.7LL?
Di po ba 1.2DL+1.6LL?
Thank you po.
Yes you can use 1.2DL+1.6LL
Sir bka po pwede mag request ng design computation sa steel column
Sure it will come soon. Thanks
sir do you have an excel template for singly reinforced beam
Sir tanong ko lang po sa isang frame ng multi storey building pwede po ba gamitin yung pinaka mataas na loads sa structural analysis para sa design ng beams kung typical lengths and section naman po para hindi ko na idesign individually kada beam. thanks po in advance.
Yes especially kung isang type lang ng occupancy. Except dancing hall ang storage rooms, but kung offices, residential, multi purpose with fixed partitions you can assume similar loadings. Liveload lang naman ang variable.
Pag nagde design ako ng multi storey building..let say 20 storey even though same loading..mas malaking size ginagamit ko sa lower level dahil malaki ang stress sa lower level compare sa higher level..gradual lang ang reduced ng dimensions..IMHO
Pwede naman but it would be expensive. Besides, I doubt that it will give you the same result per floor because of the lateral loads. If you want to save time in designing you can group the result like establish a typical zone say; all basement floors, L1-4, L5-8 and so on. It is up to the designer, diskarte mo yan, there is no right or wrong as long as you complied with the prevailing code and assign the proper loadings you are good. Thanks
Sir JS, pano po lumabas ung 65.31 sa formula nyo ng Mu=0.9*0.009*400+(1-0.59*0.009*400/(21))? iba po kasi lumalabas sa akin using excel spreadsheet formula eh. Thanks!
Your first expression should be multiplied to (not add) to the enclosed numbers. thanks
bakit po 1.4udl+1.7ull ginamit nyo? sanay po ako na 1.2DL+1.6LL ang ginagamit ko pag nagaanalysis
It's up to the designer kung saan kayo comfortable. Thanks
1:28 sir linawin ko lang po. Pag 1 story po ba na roof deck, Palagi po pala Pinned ang boundary condition ng 4 na beams?
Discretion ng designer yan, some may have treated it as fixed-ended but to me it is safer to let them(beams) free-ended to get the maximum moment at the center. Besides, I don't think column has a complete bending resistance on its free-end. Mag provide ka nalang ng extra top bar on both ends if you wish, use L/5
@@jsdesign_engineeringtv3633 ok sir. Share ko lang din po sa inyo, pag ang 1 story concrete structure nyo ay nasa seismic or typhoon prone areas, Malakas ang Lateral load at kailangan kontrolin ang Drift. Kung pinned ang boundary conditions ng lahat ng beam hindi po kaya unstable ang structure?
Thanks
@@kebzkebz6437 in theory.😆Hindi Yan sa totoong buhay.
@@generalengineerph3574 🤣🤣 Hindi Talaga totoong nangyayari sa totoong buhay, bakit? Ilang porsyento ng Mga Structures sa Pilipinas ang Dinisenyo ng isang Structural Engineer?🤔 Dahil Hindi Daw kaya ng Nakararami ang Magbayad ng isang Structural Designer. Kaya Ang mga Contractor satin, kahit hindi capable at wala experience sa structural design ay "Katulad" ng Sinabi mo ang Sinasabi 😉
16:49 sir, anung ACI code po at anung section ng code? Hindi na po pala Magdedeflect pag nasatisfy na ang steel ratio.
Thank you for your comment sir.
I can't remember the exact section, you can google it. Hindi natin sinasabi na walang maging deflection, what I have said is we are in control of the deflection. Fyi
@@jsdesign_engineeringtv3633 ok sir. Ang alam ko po kasi kaya natin chinecheck ang steel ratio ay para madetermine natin ang Tamang requirement ng bakal para hindi magkaroon ng brittle failure ang concrete beams. Thank you sir for the new knowledge.
Kung ordinary reinforced concrete po..mag de- deflect po yan Wala po sa code nakalagay na hindi mag deflect ang beam.. except Prestressed/post tension beam pag sobra ang tendon..ang tendency ay mag camber..and that will affect ang floor finishing like tiles..marbles..etc..
Hindi po ba kasama ang seismic at wind load sa pagcompute ng ultimate load?
I just gave a basic example. That should be included, I will include in my future videos please stay tune. Thanks
@@jsdesign_engineeringtv3633 looking forward po sa video nyo about sa pagcompute ng ultimate load
Sir kailan Yung lecture niyo sa doubly reinforced?
I'll try to upload it maybe next week, thanks
Sir paano po makuha ang Beam Self Weight. Thanks po
You need to get the volume(in m3) first, then multiply it by concrete unit weight (2,446kg/m3)
Sir ano po ang implication kung ang beam mo ay continous beam pero denidesign mo siya as simply supported beam?
Posibleng maging malalim ang beam depth dahil yung max. moment nag concentrate sa midspan. Thanks
@@jsdesign_engineeringtv3633 salamat sir.
