Qhov Chaw Truss Structure: Qhov Kev Xaiv Zoo Tshaj Plaws rau Cov Tsev Loj Loj

Raws li ib feem tseem ceeb ntawm spatial grid qauv, qhov chaw truss qauv nta superior mechanical kev ua tau zoo, lub teeb yuag, siab rigidity, zoo heev seismic tsis kam, tsis tshua muaj nqi thiab yooj yim shaping. Nws tau dhau los ua cov txheej txheem zoo tshaj plaws rau lub ru tsev ntawm cov tsev loj loj xws li tshav dav hlau terminals, chaw ntau pob, chaw ua yeeb yam thiab chaw nres tsheb.

Qhov chaw truss qauv yog ib hom loj ntawm spatial grid system. Nws yog ib tug spatial bar qauv tsim los ntawm cov tswv cuab tau teem tsis tu ncua thiab kev cob cog rua ntawm cov pob qij txha. Nws yog tsuas yog tsim los ua ob txheej lossis ntau txheej tiaj tiaj, sib txawv ntawm ib txheej latticed shells.

Qhov chaw truss cov qauv feem ntau yog siv rau cov qauv ru tsev, feem ntau nyob rau hauv ib txheej thiab cov duab tiaj tus. Lawv tau siv dav hauv cov tsev pej xeem suav nroggymnasiums, exhibition halls, chaw nres tsheb tosthiabtshav dav hlau terminals. Nyob rau hauv xyoo tas los no, lawv kuj tau siv rau cov tsev lag luam xws licov tsev khaws khoom, hangars thiab Hoobkas rhiav. Kev khav theeb muaj ntau yam zoo, lawv sawv tawm raws li qhov kev xaiv tseem ceeb rau cov tsev loj loj.

Loj-span-dawb qhov chaw.

Qhov chaw truss qauv yooj yim ua tiav cov kab ntawv tsis pub dawb xws li ntawm 60 txog 150 meters, tsim kom muaj kev qhib siab thiab dav sab hauv. Beijing Capital Gymnasium txais qhov chaw truss qauv nrog qhov ntev ntawm 99 meters los ntawm 112.2 meters. Qhov kom zoo dua no ua rau qhov chaw truss lub ntsiab kev xaiv rau tshav dav hlau davhlau ya nyob twg ru tsev.

Zoo kawg nkaus economic efficiency.

Cov qauv nta qis steel noj thiab tswj tau tag nrho cov nqi. Cov hlau tso ntawm Hangzhou Renhe Grain Reserve Terminal siv ob txheej txheej square pyramid qhov chaw truss, nrog qhov siab tshaj plaws ntawm 95 meters, xa cov nqi tsim kho.

Zoo heev seismic kev ua tau zoo.

Ua tsaug rau qhov siab spatial stress redundancy, zoo ductility thiab lub teeb nws tus kheej-qhov hnyav, qhov chaw truss lug outperform ib txwm ua vaj tse nyob rau hauv av qeeg kuj. Raws li lub tsev loj loj hauv cheeb tsam seismic, Beijing Daxing International Tshav Dav Hlau Terminal yog nruab nrog 1152 cais bearings thiab 160 dampers kom muaj kev tiv thaiv zoo tiv thaiv av qeeg.

Flexible architectural styling.

Cov qauv tuaj yeem paub cov duab nyuaj xws li hyperboloid, dawb-dawb nto thiab nruam nthwv dej saum npoo, ua tau raws li qhov xav tau ntawm thaj chaw tsim qauv ntawm cov tsev pej xeem niaj hnub. Lub ru tsev loj ntawm Zhuhai Tshav Dav Hlau T2 Terminal txais yuav ntev-ntev sib txawv-curvature hyperboloid hollowed steel truss. Shenzhen Bay Sports Center muab ib txheej txheej latticed plhaub thiab ob txheej txheej nkhaus truss, ob qho tib si ua haujlwm zoo li cov qauv tsim qauv.

Tsis tas li ntawd, qhov chaw truss qauv tuaj nyob rau hauv ntau yam ntaub ntawv nrog rau lub ntsiab kev faib raws li nram no:

Qhov ob-txheej qhov chaw truss, tsim los ntawm cov chords saum toj kawg nkaus, hauv qab chords thiab cov tswv cuab hauv lub vev xaib, yog daim ntawv pom zoo tshaj plaws.

Kev xaiv ntawm qhov chaw truss qauv yog txiav txim siab los ntawm ntau yam xws li lub tsev tsim qauv, kev tsim vaj tsev, kev thauj khoom, ncua sijhawm, kev txhawb nqa thiab kev tsim kho tus nqi.

Zuag qhia tag nrho, kev siv qhov chaw truss qauv ua rau tsim kom muaj qhov chaw loj dua nrog cov khoom siv tsawg dua. Tawm tsam keeb kwm yav dhau los ntawm kev txhim kho zoo thiab kev tsim kho ntsuab, qhov chaw truss ua haujlwm raws li lub hauv paus ntsiab lus ntawm cov vaj tse loj loj.
