Cov khoom lag luam

Cov roj hmab roj hmab ua (LRB) yog ib qho ntawm feem ntau dav siv cov seismic rho tawm hauv teb kev ua se kev sib cais tsim kho vaj tsev nyob rau tam sim no. Cov kev coj ua cov roj hmab tseem ceeb yog cov tshuaj uas cov seism uas muaj kev sib txuas nrog roj hmab muaj zog thiab siv hluav taws xob zoo. Los ntawm ob lub tshuab sib cais dua qub ntawm kev sib cais thiab lub zog tsis zoo, txo cov kev puas tsuaj tsim los ntawm kev siv hluav taws xob ua rau muaj kev phom sij xws li cua hlob heev. Nws cov tswv yim thev naus laus zis yog raws li:
• Txheej roj hmab lossis roj hmab shim: nws muab cov kab rov tav thiab kev txhawb nqa ntsug.
• Cov Khoom Siv Coj: Nws siv cov tshuaj tiv thaiv yas kom nqus tau seismic lub zog (lub zog Dissipation cov nqi yuav mus txog ntau dua 70%).
• Ntau txheej txheej hlau daim hlau: lawv txhim kho cov ntsug ntsug thiab tiv thaiv cov kabmob ntawm buckling thiab poob ruaj khov.
Cov khoom no ua raws li cov qauv thoob ntiaj teb ISO 22762 thiab haum rau kev siv Seismic thiab cov chaw tseem ceeb uas rhiab rau kev co. Nws yog dav thov hauv txuas hniav, cov tuam tsev, thiab vaj tse tseem ceeb.

1, theem pib ua haujlwm:

1.1, lub zog nqus tau muaj peev xwm ntawm cov txhuas ua damper

Roj hmab yog cov khoom siv uas tuaj yeem ua kom muaj zog yooj yim thiab compressed, thiab nws yuav yauv tsis muaj deformation loj thaum quab yuam yog thov tom qab tau txais kev coj tus kabmob. Cov roj hmab cov kabmob siv rau seismic rho tawm yog tsim ntawm nyias steel phiaj thiab nyias roj hmab shit pawg thiab nias. Cov phiaj hlau hlau muaj cov nyhuv hlau muaj cov txiaj ntsig tau zoo ntawm cov roj hmab deformation ntawm cov roj hmab, thiab cov roj av nrawm yog heev. Txawm li cas los xij, raws li cov roj hmab muaj cov roj hmab muaj sia, lub tensile txhav ntawm LRB cov kabmob yog qhov tsawg, uas yog kwv yees li 1/7 txog 1/10 ntawm lub compression.

1.2, deformation kab rov tav muaj peev xwm ntawm LRB

Cov phiaj hlau hlau txwv txoj cai ntsug ntawm cov roj hmab, tab sis nws tsis muaj kev cuam tshuam rau nws txoj kev deformation. Nyob rau tib lub sijhawm, cov thawj coj ua tau ua raws li qhov deformation ntawm cov kabmob ntawm cov kabmob zoo thiab nqus seismic lub zog. Txoj kab rov tav ntawm cov txhuas cov kabmob roj hmab yog ruaj khov. Vim tias muaj lub neej ntawm txoj kev coj ua, nws tuaj yeem txwv txoj kab rov tav ntawm cov kabmob. Tus qauv kab rov tav ntawm LRB seismic sib cais yog qhov me dua uas ntawm cov nyhuv cov nyhuv ntawm damping ntxiv).

1.3, ua haujlwm yam ntxwv ntawm LRB

Cov roj hmab ua cov roj hmab muab kho cov damping qhov ntau los ntawm qhov loj ntawm cov thawj coj ua. Tom qab txoj kab uas hla ntawm kev coj ua, cov txiaj ntsig tau ua rau loj dua thiab cov nqi damping nce. Txawm li cas los xij, ib lub qhov loj tshaj plaws loj loj loj yuav muaj kev cuam tshuam zoo rau kev ua tau zoo ntawm cov kabmob ntawm cov kabmob.

1.4, lub siab ntev ntawm LRB cov kabmob

Kev tshawb nrhiav kev ua haujlwm hauv cov tebchaws xws li Nyij Pooj tau pom tias LRB cov kabmob yog ib qho zoo ib yam li cov roj hmab cov roj hmab. Txawm tias tom qab 100 xyoo ntawm kev siv, cov roj hmab hauv cov kabmob nyob tsis tau. Qee qhov kev tshawb nrhiav tau pom tias tom qab siv cov kabmob LRB, nws cov yam ntxwv tseem tsis tau hloov pauv, thiab nws yog kwv yees tias nws txoj kev ua tau tsuas yog txo qis los ntawm 60 xyoo siv.

1.5, yooj yim cov neeg kho tshuab ntawm LRB cov kabmob

1.5, yooj yim cov neeg kho tshuab ntawm LRB cov kabmob
Qhov kev ua tau zoo ntawm cov roj hmab ua kua roj hmab tuaj yeem sawv cev los ntawm tus qauv bilinear. Cov yam ntxwv kab rov tav ntawm LRB cov kabmob yog cov superposition ntawm cov kev kawm kab rov tav ntawm cov roj hmab feem thiab cov kev coj ua. Cov roj hmab ua cov ris tsho roj hmab tuaj yeem nthuav tawm cov yam ntxwv ruaj khov thaum lub ntsej muag tsis txaus ntseeg yog 250%.
