L100m * W20m * H8m Steel Structure Warehouse rau siab cua Loading Area

 

 

Project Parameters: Lub Tsev Cheeb Tsam: 2000㎡

Qhov siab: 8m

Cua Siab: 250km / h

Seismic Resistance: Qib 8

Cov cheeb tsam hloov tau: Philippines, New Credonia, Tonga, Virgin Islands, Reunion Island ...

 

 

Rau cov phiaj xwm kev cob qhia steel thav duab (W20m x L100m x H8m, cua kub ceev, siab seismic fortification, tsis muaj daus), qhov no yog ib qho kev tsim scenario yam ntxwv los ntawm "siab cua siab, siab seismic tsis kam, thiab tsawg ru tsev load."

Vim yog cov cua load tshwj xeeb (250km / h, sib npaug rau Typhoon Theem 14), qhov no yuav yog tus tswj kev thauj khoom rau tag nrho cov qauv tsim. Feem ntau, steel noj ntawm lub teeb rhiav yog tswj los ntawm cua suction rau stability. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv no, lub zog cua siab heev thiab seismic rog yuav dominate seem tsim ntawm steel beams thiab steel kab.

Hauv qab no yog qhov tsim nyog tshaj plaws, kev lag luam, thiab kev nyab xeeb kev tsim qauv peb xav, nrog rau kev kwv yees siv steel.

 

 

Txhawm rau tiv thaiv 8-degree seismic fortification thiab 250km / h cua ceev, thiab xav txog 8m qhov siab tsis xav tau cov kab teeb crane, cov tswv yim yuav tsum tsom mus rau "cov kab muaj zog, kab teeb tsis muaj zog" thiab "txhim kho kev sib txuas."

 

1. Main Structural System (Lateral Force Core)

Frame Hom:Customized H-section Steel Ncej.

Yog vim li cas:Txawm hais tias huab cua thauj khoom siab thiab xav tau cov webs tuab dua, ib ntu tapered tuaj yeem siv cov khoom siv zog zoo. Nws ua kom cov ntu qhov siab ntawm kab teeb -Kem pob qij txha (qhov twg quab yuam loj tshaj) thiab txo nws ntawm nruab nrab - ncua, ua rau nws cov hlau ntau dua -ntau tshaj qhov seem.

Hom kev sib txuas:Rigid Connection (Moment Connection) ntawm kab teeb thiab kab.

Yog vim li cas:8-degree seismic fortification xav tau cov qauv kom muaj lub zog zoo dissipation muaj peev xwm thiab kev ncaj ncees. Cov pob qij txha zoo tiv thaiv lub sijhawm khoov los ntawm av qeeg, txo qis kev hloov pauv mus rau sab nraud, thiab muaj kev nyab xeeb dua li kev sib txuas sib txuas (sway kem schemes). Lawv kuj ua rau tsawg deformation nyob rau hauv cov cua siab.

Kem Base Hom:Rigid Kem Base.

Yog vim li cas:Txhawm rau tiv thaiv lub sijhawm hloov pauv loj heev (los ntawm cua thiab av qeeg), kab hauv paus yuav tsum tau txuas nrog lub hauv paus kom hloov lub sijhawm khoov.

 

2. Secondary Structure thiab Bracing System (Stability Key)

Lub Tsev Purlins:Nruam Z-section Steel Purlins (nrog rau cov pas nrig).

Yog vim li cas:250km / h cua nrawm tsim cov cua nqus cua loj heev (lifting ru tsev). Nruam Z-section steel muaj qhov tsim nyog quab yuam ntau dua li C-section steel thiab yuav tsum tau nruab nrog ob npaug- txheej nro rods lossis struts kom ruaj ntseg ntawm compression flange.

Phab ntsa Girts:C-section Steel Girts (nrog rau kab pheeb ces kaum nro).

Yog vim li cas:Phab ntsa feem ntau dais cua siab thiab nqus. C-section steel yog txaus. Txawm li cas los xij, nyob rau hauv 250km / h cua ceev, qhov sib nrug ntawm phab ntsa girts yuav tsum tau densified (pom zoo @1.0m - 1.2m), thiab kab pheeb ces kaum nro rods yuav tsum tau ntsia kom tiv thaiv kab rov tav rog.

Bracing System:

Roof Horizontal Bracing:Nruab transverse kab rov tav bracing nyob rau hauv lub gable bays thiab nruab nrab los tsim ib tug ruaj khov kab rov tav truss, hloov cua zog mus rau inter-kem bracing.

Inter-kem Bracing:Nruab rau hauv cov phab ntsa gable thiab nruab nrab. Nws yuav tsum siv seem steel bracing (tsis yog ib puag ncig steel) kom ua tau raws li qhov yuav tsum tau ua ntawm 8-degree seismic fortification.

 

3. Cov txheej txheem kaw

Roof Cladding:Customized 900 hom lossis 750 hom corrugated xim hlau vaj huam sib luag.

Yog vim li cas:Nyob rau hauv 250km / h cua ceev, zoo tib yam ntsia hlau- tsau vaj huam sib luag hom yog yooj yim tshem tawm. Nkaum-snap xauv vaj huam sib luag yuav tsum tau siv, tso siab rau cov khoom siv sib txuas los xauv cov vaj huam sib luag rau hauv qhov chaw. Qhov no muaj qhov muaj zog tshaj cua uplift kuj.

Phab ntsa Cladding:Customized 900-type lossis 750 hom corrugated Xim Hlau Panels.

Yog vim li cas:Cov vaj huam sib luag nrog cov nthwv dej siab dua muaj qhov nruj dua thiab tsim nyog rau qhov chaw siab cua.

 

 

Qhov no yog qhov taw qhia tseem ceeb. Vim tias qhov yuav tsum tau muaj cua txias heev (250km / h) thiab xoom daus load, qhov no yuav ua rau cov nqaj loj thiab kab ke ntau dua li cov kev cob qhia zoo tib yam, thaum cov khoom siv thib ob xws li purlins yuav muaj kev ntxhov siab.

 

1. Kev kwv yees hauv paus

Cua Load Conversion:Cua ceev ntawm 250km / h hloov mus rau qhov cua siab heev tus nqi (ntau tshaj li cov pa 0.35-0.55kN / m²). Qhov no yuav tsum tau lub webs ntawm kab teeb thiab kab tsis txhob nyias dhau thiab cov seem kom txaus siab.

8-degree Seismic Resistance:Yuav tsum muaj kev sib koom ua ke tsim kom muaj zog, ua rau cov hlau sib txuas tuab dua thiab loj dua.

Tsis muaj Snow Load:Qhov no tsuas yog qhov "yuag poob" qhov tseem ceeb, lub ntsiab lus ntawm lub ru tsev tuag load yog lub teeb, thiab kev ruaj ntseg yuav tsum tau rau compression flange ntawm kab teeb yog qis dua.

 

2. Kev kwv yees siv hlau ib qho khoom siv

 

Cov Qauv Txheej Txheem	Kwv yees Index (kg/㎡)	Kev piav qhia
Main Ncej (Beams + Kab)	20 - 25 kg/㎡	Txawm hais tias lub eaves qhov siab ntawm 8m tsis siab, vim yog cua siab, cov kab thiab kab -kawg yuav tsum tau thickened (piv txwv li, web thickness nce ntawm 4mm mus rau 6-8mm).
Crane Beams / Nyuj Ob txhais ceg	0 kg / ㎡	Feem ntau, tsis muaj crane yuav tsum tau ntawm qhov siab 8m, yog li cov khoom no yog 0.
Ru tsev Purlins + Tension Rods	7 - 9 kg/㎡	Vim muaj cua loj nqus, purlin specifications yuav tsum tau nce (xws li, C200 los yog Z200) thiab nro pas nrig ceev nce.
Phab ntsa Girts + Tension Rods	4 - 5 kg/㎡	Cov cua kub siab yuav tsum tau denser girt spacing thiab thicker phab ntsa thickness.
Bracing System (Inter-kem + Roof)	3 - 4 kg/㎡	8-degree seismic yuav tsum tau xav kom muaj zog bracing system.
Lwm yam (Gutters, Canopies, thiab lwm yam)	2 - 3 kg/㎡	Xws li cov phaj txuas, bolts, thiab cov khoom poob.
Tag Nrho Cov Khoom Siv Hlau	36 - 46 kg/㎡	Qhov tseem ceeb siv ntau yam

 

3. Tag nrho cov khoom siv hlau suav suav

Rhiav Projected Area: 20m×100m=2000㎡

Conservative Total Steel Consumption:2000㎡ × 45kg /㎡ =90,000kg.

Nco tseg:Yog hais tias huab cua load xam yog nruj heev, nws yuav dhau 48 ~ 50kg / ㎡, ua rau tag nrho qhov hnyav ntawm ib ncig ntawm 100 tons.

 

 

Rau qhov tshwj xeeb "siab cua, siab seismic" project, los xyuas kom meej lub rationality ntawm lub tswv yim, CBC hais kom koj tsom rau cov ntsiab lus hauv qab no thaum tsim thiab tsim:

Foundation Design yog qhov tseem ceeb:

Ntawm 250km / h cua ceev, lub zog txhawb nqa loj heev (txhawb lub ru tsev) thiab thawb lub zog (lub tsev) raug tsim tawm. Koj cov hauv paus kev sib cais yuav tsum ua kom loj heev, lossis koj yuav tsum xav txog cov hauv paus hauv paus. Tsis tas li ntawd, lub thauj tog rau nkoj bolts yuav tsum yog tuab txaus, ntev txaus, thiab sib sib zog nqus anchored.

Cov ntsiab lus ntawm kev sib txuas ntawm vaj huam sib luag:

Nyob rau hauv 250km / h cua ceev, "cov ntsiab lus txiav txim lub neej thiab kev tuag." Cov vaj huam sib luag ru tsev yuav tsum siv cov tuab tuab aluminium alloy clips (T-clip), thiab cov ntsia hlau txuas ntawm cov clips thiab purlins yuav tsum tau densified. Nws yog txwv tsis pub siv cov ntsia hlau- kho lub ru tsev panels hauv ntug cheeb tsam.

Kev siv "No Snow Load":

Txawm hais tias tsis muaj daus daus, thaum xam lub ru tsev nyob load, nws tsis tuaj yeem qis dua qhov tsawg kawg nkaus tus nqi teev los ntawm cov cai (feem ntau yog 0.5kN / m²). Txawm li cas los xij, koj tuaj yeem siv cov ntsiab lus no los so me ntsis rau kev tsim qauv ntawm kev txhawb nqa sab nraud rau compression flange ntawm kab teeb, uas tuaj yeem pab txuag tau me ntsis steel noj.

 

Cov ntsiab lus:Rau hom khoom lag luam no, cov tswv yim tsim nyog tshaj plaws yog kev kho H-section steel rigid thav duab + snap-lock ru tsev panels. Qhov kwv yees tsim nyog steel noj yog nyob nruab nrab36-46 kg / ㎡. Thov nco ntsoov kom muaj tus kws tshaj lij kev tsim qauv tshuaj xyuas cov cua thauj khoom kom ntxaws, vim tias 250km / h yog qhov xwm txheej hnyav uas yuav xav tau cov ntawv ceeb toom tshwj xeeb cua uplift rau kev txhawb nqa.

 

 

Sau ntawv: Cov luj uas tau teev tseg hauv qab no yog theoretical net weights. A3–5%nyiaj pub rau pov tseg yuav tsum tau ntxiv thaum lub sij hawm yuav khoom.
