Nyob zoo, tuaj nrog peb cov khoom!
/projects/construction-of-steel-space-grid-museum-project/

Qhov project no yog qhov tshwj xeeb zoo li qhov sib txuas qhov chaw ncej / qhov siab yog 35 meters / tag nrho ntev 88 meters / tag nrho ncua 40 meters

Reinforced qhob ncej qauv.Siv thev naus laus zis cais tawm seismic, cov txheej txheem seismic cais ntawm lub tsev tseem ceeb nrog lub chaw nres tsheb hauv av yog nyob nruab nrab ntawm cov qauv kev nce siab, thiab cov txheej txheem seismic cais ntawm lub tsev suab nyob ntawm -1.800m thiab ± 0.000m.Lub thickness ntawm sab saum toj phaj ntawm seismic cais txheej yog ntau dua los yog sib npaug rau 160mm.

1. Raws li 2016 tsab ntawm "Code for Seismic Design of Building Structures" (GB50011-2010), tom qab tsim cov tshuab seismic cais tawm, cov qauv sab saud ntawm qhov project no tuaj yeem tsim raws li qhov siab tshaj plaws kab rov tav seismic influence coefficient αmax ntawm 0.16.Yog xav paub meej txog kev suav thiab kev txheeb xyuas, thov mus saib "Xaiv thiab Kev Tshawb Fawb Tshaj Tawm ntawm Seismic Isolation Design".

2. Cov roj hmab bearing yog teem rau hauv qab ntawm lub pier sab sauv thiab sab saum toj ntawm lub pier qis, LNR txhais tau hais tias ntuj roj hmab bearing, LRB txhais tau hais tias roj hmab bearing nrog txhuas core.

3. Seismic isolation design drawings yuav tsum tau siv tag nrho ua ke nrog rau cov qauv kev tsim kho vaj tse.

(1) Qhov kev hloov pauv ntawm 100% kab rov tav txhua yam khoom ntawm lub tsev tag nrho seismic cais roj hmab bearings los yog scaled qauv siv nyob rau hauv qhov project no yog tsawg dua ± 20% ua ntej thiab tom qab 8 zaug ntawm 250% kev xeem.

(2) Txhua qhov tshwj xeeb ntawm seismic cais cov roj hmab bearings siv nyob rau hauv txoj haujlwm no yuav tsum ua kom tau raws li qhov kev ntsuam xyuas loj deformation ua pov thawj: nyob rau hauv qhov ntsuas kev ntxhov siab, qhov kawg shear deformation yuav tsum tsis pub tsawg dua 450% ntawm tag nrho cov tuab ntawm cov roj hmab.

(3) Reciprocating 3 cycles ntawm cyclic loading, thiab yuav tsum tau xav txog nyob rau hauv cov ntaub ntawv txheeb xyuas hom.

(4) Thaum lub shear strain yog 0, qhov kawg tensile kev nyuaj siab yuav tsum tsis txhob tsawg tshaj li 4.0Mpa rau tag nrho cov specifications ntawm seismic cais bearings nyob rau hauv qhov project no, thiab ib tug xeem daim ntawv qhia yuav tsum tau muab.

(5) Txhua qhov tshwj xeeb ntawm lub tsev seismic cais cov roj hmab bearings siv nyob rau hauv qhov project no yog kuaj tom qab kev laus thiab qhov kawg deformation ntawm bearings tsis tsawg tshaj li 360%, thiab ntsug txhav hloov tus nqi ntawm cov bearings ua ntej thiab tom qab kev laus yog nyob rau hauv lub ± 20%.

(6) Lub 60-xyoo creep variable ntawm kev rho tawm roj hmab bearing yog tsawg dua los yog sib npaug li 5%.

4. Lub chaw soj ntsuam uas koom nrog hauv kev tshuaj xyuas cov seismic cais tawm thiab cov khoom siv poob siab hauv lub xeev no yuav tsum yog lub chaw haujlwm nruab nrab ntawm tus neeg muaj kev ywj pheej raws li txoj cai, thiab lub chaw kuaj xyuas yuav tsum tsis txhob tshaj tawm tsab ntawv tshaj tawm rau lwm tus neeg ua haujlwm rau cov tuam txhab tsim khoom.
