Tus Qauv Tsim Thiab Kev Ntsuam Xyuas Ntawm 8-Story Multifunctional Prefab Tsev Rau Cov Neeg Siv Khoom Philippine

Tus Qauv Tsim thiab Kev Ntsuam Xyuas ntawm 8-Story Multifunctional Building rau Philippine Client

 

 

Qhov project no yog 8-zaj dab neeg multifunctional lub tsev nyob hauv Manila, Philippines, nrog rau tag nrho qhov ntev ntawm 20m × 20m. Qhov siab ntawm txhua lub tsev yog tsim raws li hauv qab no: pem teb 1 (chaw nres tsheb) ntxiv rau mezzanine tag nrho hauv 6m; pem teb 2 (warehouse) siab yog 6m; lub 3rd thiab 4th pem teb (chaw ua hauj lwm cheeb tsam) yog nyob rau hauv 4.5m thiab 3.4m feem; lub 5th mus rau 7th pem teb (qhov chaw nyob) yog txhua 3.4m siab; pem teb 8 (ru tsev pej xeem chaw) ntxiv rau lub ru tsev qhov siab yog 2.8m. Rau qhov chaw optimization, tsuas yog 3 kab ntawm cov kab ke ntawm cov txheej txheem: Axis A muaj 4 kab tag nrho, qhov sib nrug ntawm Axis A thiab Axis B yog 13.2m, thiab qhov sib nrug ntawm Axis B thiab Axis C yog 6.8m. Qhov sib nrug ntawm 4 kab ntawm Axis A yog 5.9m (1-2 axis), 8.2m (2-3 axis), thiab 5.9m (3-4 axis) feem.

 

 

 

National Structural Code of the Philippines (NSCP) 2015: Tswj tag nrho cov qauv tsim, suav suav, khoom siv, thiab kev nyab xeeb.

Philippine Building Code (PBC) 2004: Tswj kev siv lub tsev, kev nyab xeeb hluav taws, thiab kev ua haujlwm ruaj khov uas cuam tshuam rau ntau lub tsev (chaw nres tsheb, warehouse, chaw ua haujlwm, thaj chaw, pej xeem chaw).

Seismic Design Criteria: Manila nyob rau thaj tsam nruab nrab seismic nrog Peak Ground Acceleration (PGA) ntawm 0.15g; tus qauv tsim siv seismic siv 7 (0.15g) rau kev tiv thaiv -seismic check.

Cua Load Criteria: Basic cua ceev hauv Manila yog 45 m/s (Qeb 3); cua load xam raws li NSCP 2015 Tshooj 28, xav txog cua siab faib thiab cov qauv cua coefficient.

 

 

Tuag Load (DL): Raws li NSCP 2015, ua ke nrog lub tsev muaj nuj nqi: lub ru tsev (2.5 kN / m²), nyob pem teb (2.0 kN / m²), chaw ua hauj lwm pem teb (2.5 kN / m²), warehouse floor (5.0 kN / m²), chaw nres tsheb (4.0 kN / m²), mezzanine (3.0 kN / m²); tus kheej- hnyav ntawm steel qauv cov tswv cuab yog xam raws li qhov tseeb seem loj.

Nyob Load (LL): Chaw nyob (2.5 kN/m²), chaw ua hauj lwm cheeb tsam (3.0 kN/m²), warehouse (10.0 kN/m²), chaw nres tsheb (2.5 kN/m² rau ib lub tsheb, ntxiv rau 1.0 kN/m² rau cov neeg taug kev), ru tsev public space (2.0 kN/m²).

Seismic Load (EL): suav nrog cov lus teb spectrum txoj kev, xav txog kev faib khoom loj, cov yam ntxwv nruj, thiab qhov sib piv (0.05 rau cov qauv hlau).

Cua Load (WL): xam raws li cua siab (w=0.613 × V², V=45 } m / s) thiab faib rau txhua pem teb raws li qhov siab thiab cov qauv duab; cua-induced vibration yog kuaj xyuas qhov siab- nce siab (5-8 pem teb).

Lwm yam Loads: Daus load tsis suav hais tias (Manila yog ib cheeb tsam kub); av qeeg-induced Secondary loads (xws li P-Δ effect) thiab kub ntxhov siab yog suav nrog hauv kev kuaj xyuas.

 

 

Xav txog kev ua haujlwm hauv lub tsev, qhov xav tau ntawm qhov chaw, thiab cov cai hauv zos, cov qauv steel ncej tau txais yuav, uas muaj qhov zoo ntawm lub teeb yuag, siab zog, zoo ductility, thiab kev tsim kho ceev. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:

Kem: Steel H-beams yog siv; cov kab ke yog txiav txim siab raws li cov load-cov kabmob muaj peev xwm ntawm txhua pem teb. Lub 1st-2nd pem teb (chaw nres tsheb + warehouse) txais yuav H600 × 250 × 8 × 12 hli vim muaj kev thauj khoom loj; 3rd-4th pem teb (chaw ua haujlwm) txais H500 × 200 × 7 × 10 mm; lub 5th-8th pem teb (chaw nyob + ru tsev) txais H400 × 200 × 6 × 8 mm.

Beams: Steel H-beams yog siv rau hauv pem teb kab teeb thiab ru tsev kab teeb. Cov kab teeb ntawm Axis A thiab Axis B (13.2m ncua) txais H500 × 200 × 7 × 10 mm (1st-2nd pem teb) thiab H450 × 180 × 6 × 9 mm (3rd-8th pem teb); cov kab teeb ntawm Axis B thiab Axis C (6.8m ncua) txais H400 × 180 × 6 × 8 mm (tag nrho cov plag tsev); lub mezzanine beams txais H300 × 150 × 6 × 8 mm.

Pem teb Slab: Composite pem teb slab (steel lawj + pob zeb) yog saws, nrog ib tug pob zeb thickness ntawm 120 hli (chaw nyob / chaw ua hauj lwm), 150 hli (warehouse / chaw nres tsheb), thiab 100 hli (mezzanine / ru tsev); steel lawj qauv yog B-120, nrog lub thickness ntawm 1.2 hli.

Lateral Resistance System: Cov ncej steel nws tus kheej muab lateral tawv; Nyob rau hauv tas li ntawd, kab pheeb ces kaum braces yog teem nyob rau hauv lub ces kaum ntawm lub tsev (Axis A-1, A-4, C-1, C-4) los txhim kho lateral tsis kam tiv thaiv cua thiab seismic loads.

 

 

Cov khoom siv hlau suav nrog tag nrho cov tswv cuab tseem ceeb: txhua kab, kab teeb, pem teb steel decks, kab pheeb ces kaum, thiab cov khoom sib txuas (bolts, vuam cov ntaub ntawv, thiab lwm yam). Ib qho nyiaj 10% yog ntxiv rau cov khoom sib txuas (bolts, vuam, thiab lwm yam) raws li qhov hnyav ntawm cov tswv cuab tseem ceeb, uas yog nyob rau hauv txoj kab nrog cov qauv kev suav ntawm cov qauv steel.

Ntawm qhov chaw ntawm lub rooj sib tham Manila cov cai hauv zos thiab ua kom muaj kev nyab xeeb ntawm cov qauv, cov kev ntsuas kev txhim kho hauv qab no tuaj yeem siv los txo cov kev siv steel, txhim kho cov qauv kev ua haujlwm, thiab txo cov nqi ntawm qhov project, tsis cuam tshuam rau lub tsev ua haujlwm thiab qhov chaw yuav tsum tau ua.

 

 

Kem: Rau 5th- 8th pem teb (chaw nyob, chaw thau khoom me me), cov kab ke tuaj yeem ua kom zoo dua los ntawm H400 × 200 × 6 × 8 mm rau H350 × 180 × 6 × 8 mm. Kev ntsuam xyuas qhov kev ntxhov siab qhia tau hais tias qhov kev ua kom zoo tshaj plaws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom thauj khoom, txo cov hlau siv li ntawm 8% rau cov kab no.

Beams: Rau cov kab teeb ntawm Axis B thiab Axis C (6.8m ncua, me me), ntu tuaj yeem ua kom zoo dua los ntawm H400 × 180 × 6 × 8 hli mus rau H350 × 180 × 6 × 8 hli, txo cov steel noj li ntawm 6% rau cov kab teeb no.

 

 

Tam sim no kab pheeb ces kaum yog teem rau tag nrho 8 pem teb; lawv tuaj yeem ua kom zoo dua los npaj rau lub sijhawm (txhua 2 plag tsev) rau 5th-8th pem teb (chaw nyob, me me lateral load). Qhov kev hloov kho no tuaj yeem txo tus naj npawb ntawm cov braces los ntawm 50% rau cov plag tsev sab saud, thaum ua kom lub ntsej muag nruj ua tau raws li qhov yuav tsum tau ua, txo qis steel noj li ntawm 5% rau cov txheej txheem bracing.

 

 

Tus tsim tam sim no txais yuav Q235B thiab Q355B steel; nws tuaj yeem hloov tau nrog tag nrho Q355B lossis siab - lub zog steel rau cov kab loj thiab kab teeb (1st- 4th pem teb, cov khoom loj). yog li qhov loj me tuaj yeem raug txo kom tsim nyog thaum tuav tib lub peev xwm thauj khoom. Qhov kev ua kom zoo no tuaj yeem txo cov kev siv steel li ntawm 10-12% rau cov tswv cuab tseem ceeb.

 

 

Rau 5th - 7th pem teb (chaw nyob hauv cheeb tsam), qhov sib xyaw hauv pem teb slab pob zeb yuav raug txo los ntawm 120mm mus rau 100mm, thiab steel lawj thickness yuav khaws cia ntawm 1.2mm. Qhov kev hloov kho no tuaj yeem txo cov neeg tuag hauv pem teb, yog li txo cov kev xav tau ntawm cov kab thiab kab teeb, thiab txo qis kev siv hlau los ntawm kwv yees li 3-4%.

 

 

Tom qab kev txhim kho kom zoo, tag nrho cov khoom siv hlau tuaj yeem raug txo los ntawm 15-20%, los ntawm thawj 200.65 tons rau 160.52-170.55 tons. Chav tsev steel noj yuav raug txo mus rau 50.16-53.30 kg / m², uas tseem nyob hauv qhov tsim nyog thiab tuaj yeem txo cov nqi tsim nyog thaum ua kom muaj kev nyab xeeb thiab ua tau raws li cov cai hauv zos.

 

Cov qauv tsim ntawm 8- zaj dab neeg ntau lub tsev ua tau raws li Manila cov cai hauv zos (NSCP 2015, PBC 2004) thiab cov kev cai thauj khoom, nrog rau tag nrho cov steel noj ntawm kwv yees li 200.65 tons thiab ib chav tsev steel noj ntawm 62.7 kg / m². Rau lwm thaj chaw: nws muaj feem xyuam rau hauv Manila; yuav tsum tau hloov kho nyob rau hauv New Caledonia, Papua New Guinea, thiab Peru (nrog rau cov khoom siv hlau txuas ntxiv); thiab tsis pom zoo hauv Tonga thiab Chile (vim yog ultra-siab seismic / cua load yuav tsum). Los ntawm kev ua kom zoo tshaj plaws, kev hloov khoom siv, thiab kev hloov kho, kev siv hlau tuaj yeem raug txo los ntawm 15-20% yam tsis muaj kev cuam tshuam rau cov qauv kev nyab xeeb, uas muaj txiaj ntsig zoo rau kev lag luam.
