Sib sau ua vaj tse | Kev qhia txog kev ua tau zoo tshaj plaws thiab muaj cov thev naus laus zis tshiab-sib sau ua ke cov qauv kev ua haujlwm truss

Cov kev zoo heev

Lub rooj sib sau ua ke Steel ncej Staggered stuss qauv system yog tsim ntawm cov ncej kab, transverse dav hlau trusses thiab pem teb. Cov kab tau npaj rau hauv lub tsev uas tsis muaj chaw nyob hauv cov tsev, thiab qhov kawg ntawm cov kab ke uas nyob ib sab ntawm cov chaw nyob ntawm lub tsev sab saud thiab qis dua. Ib qho kawg ntawm cov Slab yog txhawb nqa ntawm cov chord sauv ntawm truss, thiab lwm qhov kawg yog txhawb nqa ntawm cov chruss qis dua. Nws tuaj yeem ua qhov qhib loj nrog ob zaug sib nrug, tau txais loj dua qhib thiab qhov tob ntawm cov khoom lag luam ntawm cov khoom lag luam ua haujlwm thiab ua kom yooj yim. Nws tuaj yeem ua rau sab nrauv qhov rooj, teeb tsa txoj kev hauv tsev lossis cov chav nyob sib ze uas tsis muaj cov nqe nyob nruab nrab ntawm cov neeg nyob hauv lub siab. Nyob rau tam sim no, yuav luag txhua tus steel qauv khoom rau cov chav tsev tsim, thiab cov nqi hlau loj ntawm cov tsev ua haujlwm muaj kev sib raug zoo nrog cov kev xav tau ntawm cov tsev.

Daim duab 1 Lub teeb tsa Truss Aponometric

Vim yog cov yam ntxwv ntawm cov chaw ua haujlwm ntawm cov qauv sib xyaw ua ke thiab cov yam ntxwv ntawm cov kev ntsuas ntawm cov kev xav ntawm cov kev xav ntawm cov kev ntsuas ntawm cov kev ua yeeb yam ntawm cov khoom siv tsoos, thiab cov seismic Cov kev ntsuas kev teeb tsa thiab kev xam xyuas cov kev sib txuas ntawm hauv pem teb slab thiab lub dav hlua truss chord yuav tsum tau txiav txim siab tshwj xeeb tshaj yog. Tshwj xeeb, cov seismic-resistant qauv ntawm pem teb slab thiab dav hlau truss chord kev twb kev sib txuas yuav tsum tau raug tshuaj xyuas thiab kev suav.

Cov qauv ntawm staggered truss tsuas yog muaj cov steel txhua, dav hlau trusses thiab ncej kab teeb. Hauv cov theem ntau lawm, dhau li ntawm kev sib ntsib cov qauv hlau ua kom pom tseeb tias tsis muaj qhov sib txawv ntawm cov trusses sab nraud ntawm lub tsev trusses thaum lub sijhawm tsheb thauj mus los.

Thaum kev txhim kho kab, trusses, kev zawm hniav thiab lwm tus tswv cuab loj hauv kev tsim kho ntawm staggered stimilization system. Nyob rau hauv cov txheej txheem ntawm txhim kho pem teb slab, sandmetrical nqa yuav tsum tau saws tiv thaiv kom muaj kev ruaj khov ntawm trusses hauv cov txheej txheem ntawm sab nraud.
