03 Wind Load

sir, quick question lang, sa windward portion po ng wall, diba pwedeng gawing triangular load yung pressure jan? zero sa base ng wall tas 1.074 kPa sa 4.5m, and so on and so forth? or dapat ganyan talaga na nakabloke?

Sir, after that e check pa din yung wind pressure parallel sa roof ridge?

hay sana ikaw na lang naging prof ko sa struc theory HAHA thank you sa explanation!

kaso di ko ma gets bakit 4.5 m huhu

Sir tanong ko lang po kung magcocompute pa rin ba ng windward at leeward sa roof kahit naka roof slab ang structure?

thank you sir sobrang detailed ng pagkakaexplain mo sinalba mo ako sa aking structural theory!!!

Sir,sa roof pressure coefficient, paano po kung 11.34° ang roof angle at di po exact 10°?

Sir what if open roof deck? saan mag bbase para makuha yung Cp ng roof?. Thank you

Salamat sa effort. Helped a lot. Hoping you can come up with a clearer presentation tool. But all in all its a thumbs up sir. Kudos to you & your future tutorial videos.

Sir, paano po if sa Windward roof refers to table 207 B.4-1 yong nacompute na h/L=0.825. Ang nandon lang sa table ay; <0.25, 0.5 at >10, ano po pipiliin na condition po?

Yung suction condition po susundin b yung sign ng mkukuhang pressure? Like kung (+) is towards the surface at if (- )is away from the surface? Which means possible na same ang direction ng burst at suction sa isang surface? Thanks po.

thank you sir!!!!!!!! -RESPECT from -Iloilo

Hello po sir, pwedi ba mag tanong kung ano po ang gamitin na formula para makuha yung fixed end moments/forces sa bawat member?

Sir yung 8 storey ba considered as rigid building ?

pwede po ba mahingi ang powerpoint mo, sir?

Ano Yung h/2 sa roof angle below 10deg

Liliit po yung force pataas? 55kN ,then gamit area na (1.5*11.5) may makukuha na 29.6kN o (6*11.5) gagamitin para lumaki?

Pwede bang roof wind load nitong mwfrs na gamitin sa pag-design Ng purlin, truss? Medyo hassle na Kasi pag another computation for Component& cladding

Paano naman po kapag North-to-South direction ng gable roof din?

I just would like to comment on the use of Kh & Kz...Kz is used in determining the qz (velocity pressure) which is variable with height(z). Whereas Kh is used in determining qh (constant velocity pressure) calculated using mean height. Normally, the windward pressure varies with height while the leeward is constant.

Hi, sir! Can I ask po kung pano malalaman yung Concentrated Load kapag monoslope roof?

Sir, paano po yung sa roof pressure coefficient pag flat ang roof.. specifically slab lang po siya, thank you.

Hi sir, ano pong gagamitin na total wind load sa pagcompute ng factored loads. Thank you po.

sir paano po kaya pag curved roof?

Thank you sir for this video. Sir what if hindi po sya flat terrain, pano po makukuha yung topographic factor. Thank you po

Hello po sir, hindi po ba 12.056 yung value ng h? Don sa 8+23tan10? Thank you po.

Salamat sir

sir ask ko lang po ano na po next step after po makuha both burst and suction condition pressures? ano po ang pipiliin sa dalawa? gagamitin po ba yung dalawang yon for member analysis po kung sakali?

eave height shall be used for roof angle less than or equal to 10 degrees. therefore h= eave height. Sabi ng teacher ko. hahahah!

thanks

Sir pwde ba malaman yung truss analysis kasi yung sa explanation nyo puro leeward yung sa roof. Nasanay kasi ako na windward lang yung kinoconsider sa analysis ng truss at yung leeward walang value.

Hello po ask ko lang po paano po ulit naging 9.5 yung alpha and naging 274.32 yung zg? thank you po

sir pano po pag ganito,
ang structure ko po kasi is 2 story
completely open po sya sa first floor, as in wala po talagang walls
then sa second floor po ang kalahati is roof deck and other half is composed of room units

Sir Gab, possible din po ba na maghold ng wind pressure ang roof deck? Wala po kasi ako mahanap na refernce sana masagot niyo agad. NOTIICE

possible po ba na it's either sunction or bursting condition lang ang mareceive ng bldg?

Sir Gab good afternoon po, pano po pag yung ratio ng L/B sa leeward side is 1.67 round up po ba para yung Cp /coefficient is maging 2. wala po kase sa table. thank you po Sir GAB!

sir what if 0.46 yung h/L need pa po ba interpolate?

mayron po ba kayo seismic load.

sa h value na nakuha ko 12.0555

thank you sir!!!

Nice

height = 16 units

This Gil Bermejo, P.E.

The Formula for the Kzt = (1+K1+K2+k3)^2 is wrong see attached screen shot.

I believe the correct formula should be: Kzt = (1 + K1xK2xK3)^2, see Eq. 207A.8-1

I think there are topographical errors in plus (+) sign and the multiplication (x) sign.

Hello po, sir. What if yung h/L is equal to 0.97?

Evening po Sir
Ask ko lang po sana kung ano po yung basic wind speed sa palawan? Wala po kasing nakalagay sa figure ng category 3, 4 at 5 po para po sa palawan.

Good afternoon po sir
Paano po malalaman yung roof pressure coefficient C_p kung ang h/L is 3.140 at ang roof ay merong 8°?
