Qhov zoo: Nws yog qhov tseem ceeb vim muaj zog heev. Lub tensile thiab compressive lub zog ntawm cov hlau yog loj dua li ntawm cov ntaub ntawv xws li pob zeb, thiab cov khoom yuav muaj me me cross-section rau tib lub load; tus kheej qhov hnyav ntawm cov hlau tsuas yog 1/3 mus rau 1/5 ib feem ntawm cov pob zeb ua vaj tse, uas tuaj yeem txo qhov kev xav tau ntawm lub hauv paus bearing peev xwm, yog li nws yog tshwj xeeb tshaj yog haum rau tej yaam num ntawm cov av mos foundations. Thiab qhov thib ob, nws yog kev tsim kho siab. Ntau tshaj 80% ntawm cov khoom tuaj yeem ua tiav hauv cov chaw tsim khoom los ntawm cov qauv txheej txheem thiab muab sib sau ua ke ntawm qhov chaw ntawm bolts lossis vuam, uas tuaj yeem nqa lub voj voog kev tsim kho rau 30% ~ 50% ntawm cov qauv pob zeb. Thiab qhov thib peb, nws yog qhov zoo dua hauv kev tiv thaiv av qeeg thiab Green Building. Zoo toughness ntawm cov hlau txhais tau hais tias nws tuaj yeem deformed thiab nqus lub zog thaum muaj av qeeg kom nws qib seismic tsis kam siab dua; Tsis tas li ntawd, ntau tshaj 90% ntawm cov hlau yog rov ua dua tshiab, uas txo cov khoom siv pov tseg.
Qhov tsis zoo: Qhov teeb meem tseem ceeb yog tsis zoo corrosion kuj. Qhov chaw ntub dej, xws li tshuaj tsuag ntsev rau ntawm ntug dej hiav txwv ib txwm ua rau xeb, feem ntau ua raws li kev tiv thaiv corrosion txheej txhua txhua 5-10 xyoo, uas ua rau cov nqi mus sij hawm ntev. Qhov thib ob, nws qhov hluav taws kub tsis txaus; Lub zog ntawm cov hlau txo qis heev thaum kub ntau tshaj 600 ℃, hluav taws kub retardant txheej los yog hluav taws kub tiv thaiv cladding yuav tsum tau siv los ua kom tau raws li cov kev xav tau ntawm cov hluav taws kub sib txawv. Tsis tas li ntawd, tus nqi pib yog siab dua; tus nqi ntawm cov khoom siv hlau thiab kev ua haujlwm rau lub tsev loj lossis cov tsev siab siab yog 10% -20% siab dua uas cov qauv ua vaj tse zoo tib yam, tab sis tag nrho cov nqi ntawm lub neej tuaj yeem ua kom tiav los ntawm kev tsim nyog thiab kev saib xyuas mus sij hawm ntev.
