It should not be “the block” but the number of shear areas and tensile areas that matter. But in case these blocks ate identical, then you may multiply it to the number of blocks.
Hello Sir, hindi po ba dapat ang Value ng "Effective Diameter" for 16mm Bolt is 20mm? as per NSCP 2015? Salamat po sir Bolt Diameter= 16mm Nominal Diameter= 16mm + 2mm= 18mm Effective Diameter = 18mm + 2mm = 20mm
Sa pagkaka alam ko according sa code 1/16 inch so around 1.6mm siya in SI unit. If diameter ng bolt ang given you have to add twice of 1/16 inch or 1.6mm so total of 1/8 inch or around 3.2mm. but if diameter of hole was given you have to add only once. From 1.6mm to 2mm rounded up lang ata para lang makuha yung most critical area, also para maging conservative yung makukuhang value ng stress and load. Sana po makatulong.
Yes, from the principle that block shear is combination of tension and shear and in tension, stagger is considered, then it is possible that the tension part in block is in staggered manner.
@@june-junesantos2308 Salamat sir! Laking tulong po. Okay lang po sir sobrang linaw naman po nang turo nyo lalo na po sa concepts. Thanks po talaga sir!
The problem asks for "Ultimate" strength, it means, Factored load ang gagamitin, hence, LRFD shall be used. If the problem asks for "service" or "allowable" then ASD shall be used.
sir bakit po mas mataas yung 2/3d pero ang ginamit yung 0.9? thank you po.
Pansin ko rin, 0.85 po ba dapat?
Good job po sir. Magtetake ako for nov 2022 CELE and napadali ang explanation mo for block shear.
Dba ang u=.85 sir?
Anlupet sir! Tapos ang ganda ng sulat nyo hehe salamat!
Ganda ng sulat sir! Idol.
ano po yung recommended books nyo, sa last part ng video, to practice tensile member problems?
Mataas yung 2/3 edi dapat po yung 0.85 gamitin
Bakit po i minus lagi sa 3.2?
Very clear explanation, Sir! Thank you po for this video. Any chance na may topics/examples po about built-up sections po?
Sir question lang po. Pano po pag staggered po yung bolts sa plates pano po yung icoconsider na block shear dun? Thank you po .
aside from you good delivery, i admire your penmanship,,aha
HINDI PO BA YUNG u DAPAT E 0.85?
sir kung sakali kukunin yung allowable strength based on blockshear mumultiply pa po ba kung ilang blocks..thankyou po

Bolt Diameter= 16mm
Nominal Diameter= 16mm + 2mm= 18mm
Effective Diameter = 18mm + 2mm = 20mm
Yun din nga na notice ko

sir applicable po ba ang block shear sa staggered bolts? especially kung lahat ng elements like angle bar, are all bolted?
Yes, from the principle that block shear is combination of tension and shear and in tension, stagger is considered, then it is possible that the tension part in block is in staggered manner.
@@june-junesantos2308ahhh noted sir. thank you so much po.
8:43 Sir hindi po ba 0.85 yung U?
sorry, yes, it's 0.85.
@@june-junesantos2308 Thanks sir sabi na po eh typo lang.
Yung column po ba sir mata-topic nyo rin po?
Scopper Gaban next video n yung column hehe. Salamat rin di ko napansin 😅

bakit po LRFD ung ginamit sa C

payat mo dyan sir
pa fs po lodi
First. haha
