Thank you so much for watching this video. Please share this video so we can make our column design be seismic resistance, so we can be ready for the big one!! Kudos to all structural engineers of the Philippines 🇵🇭
Hello you can check this Facebook page. I wast able to make a video hehehe but my presentation is ready m.facebook.com/stffness/?tsid=0.6479908061907906&source=result
Yes I will, thanks for watching. But in advance summation of Mcol should be greater than or equal to 6/5 Sum. Mbeam at Joint for strong column weak beam.
Yung 600mm distance ng splices sa 50% na Yun? Sample 8pc-16mm rebars, 4pc yung isplice dapat Di pantay yang 4pcs? Pano kung 4m height of col. Mid-half 2m, 50d= 800, bale 4*800 +3*600space=5m sobrasobra. Or Yung 2 lang pantay alternate, bale 2*800+600= 2.2m sobra parin sa mid-half na 2m. Pwede bang ignore nalang yang 600spacing.
Hindi po, you can splice the other half dun sa susunod na floor. If not, otherwise use Class B Tension Lap Splice with, 600mm distance pa din ng dalawang na splice. Ayaw kasi natin magkaroon ng weak section
@@allyce06 no, please check table of Lap Splices given in the plans. If not provided yes 40d is enough but please take not only us thus for 3000psi ONLY
So the spacing requirement that it should be the smallest of the following: 48db 16db least dimension of column ... are only for axially loaded column only?
Hello, as for the joint tie zones, ACI and Industry standard limits to 100mm spacing on JOINT tie zone (see example Seismic Design of Reinforced Concrete Special Moment Frames, section 5.3) and we should check its joint shear capacity.
@@janlhesternavasca3160 thanks for reply po! may mga napapanoud kasi ako ang use nila sa special confining zone is 50mm spacing, then sa staad tutorials naman na napapanoud ko ang minimum allowed ng program is 75mm hehe
Oo yun binibigay nila pero for construction issues as much as possible idesign natin sa 100mm lang mahirap kasi lalo na pag sa may joint hirap ilagay ang rebar ng beam
@@janlhesternavasca3160 sir may rule po ba na beam depth should be greater than 1/4 of clear span? what happens po if beam depth exceeds 1/4 of clear span?
@@janlhesternavasca3160 under ACI 418 sec 9.9 "Deep beams are members that are loaded on one face and supported on the opposite face such that strut-like compression elements can develop between the loads.."

Great Tutorial far beaten ang mga Indian tutorials :D Waiting For Beam SMRF
nice vid sir, i watched so many vid about this but this is the best one, keep up the good work sir and thank you!
It's been a while I'll try to upload Requirements for SMRF Beams this week. Please follow stiffness structural engineers on Facebook thank you

Excellent! very informative, keep up and continue the good work, expecting more from you, thank you very much sir.
Looking forward for the seismic analysis and detailing videos po sir. Godbless po
Hintayin ko ung seismic detailing for RC Beams sir! Sana makagawa po kayo ng video tungkol doon.
Salamat Engr. Sa video
Great discussion sir. Can you discuss also the provision for strong column-weak beam and beam-column joint? Thanks in advance.
Yes I will, thanks for watching. But in advance summation of Mcol should be greater than or equal to 6/5 Sum. Mbeam at Joint for strong column weak beam.
Beam SMRF naman po Master. Thank you po. More videos pa po
Thank you po Sir sa presentation, meron din po ba kayong file sa beams at slabs for SMRF?
Thanks engr.
What if nagawa na po yung first floor pero yung iniwan pong abang ay kaunti lang, di na po kaya magsplice sa center half, ano po kaya gagawin

@@allyce06 no, please check table of Lap Splices given in the plans. If not provided yes 40d is enough but please take not only us thus for 3000psi ONLY
saan Po sa code Yung 600mm from end to end na requirement sa splice zone?
Thank you so much po sir. Ask lang po sana if pwede po makahingi copy ng presentation nyo po? Thanks again.
Thanks for watching and subscribing to my channel engr. I'll be uploading the presentation here in the description below maybe tomorrow :)
hello engr. i've already uploaded the file in the description below.
thanks engineer
Thanks sir, happy to share sir :) I hope it helps. Please subscribe to my channel for more structural engineering guides thank you :)
So the spacing requirement that it should be the smallest of the following:
48db
16db
least dimension of column
... are only for axially loaded column only?
That is for non seismic detailing. The spacing requirement are based from the required shear Vs carried by the ties.
That is maximum spacing for Non seismic detail column
What about Joint Tie Zones what are the specified spacing of Ties
Hello, as for the joint tie zones, ACI and Industry standard limits to 100mm spacing on JOINT tie zone (see example Seismic Design of Reinforced
Concrete Special Moment Frames, section 5.3) and we should check its joint shear capacity.
pero ginagamit ng archi. 200mm column shortest dimen. hirap ipasa s seismic joint shear/flexure..sir yan b ung book n kulay green ata yun?
Yung green is for wind calculations. Haha challenge yung 200 mm na column pero kaya naman 😅
@@janlhesternavasca3160 sir my reference k b jan regarding sa FEA ?
Di na pasado sa SMRF yang 200mm
what's the lowest possible tie spacing allowed? 50mm or 75mm po ba?
As much as possible 4 inches or 100mm lang
