1. Cov yam ntxwv geometric ntawm ntu ntu ntawm cov yeeb nkab yog qhov zoo, lub raj phab ntsa feem ntau nyias nyias, cov khoom seem yog faib nyob ib ncig ntawm cov duab, qhov cross-sectional rotation radius muaj lub vojvoog loj, thiab nws muaj lub zog sib tw-resistant. tawv. Lub zog siab, thiab theem ntawm qhov ncaj thiab qhov loj me ntawm cov kav dej txias-forming yog zoo dua li cov seem ntawm qhov kub-dov qhib.
2. Los ntawm qhov kev xav ntawm kev tiv thaiv-kwj dynamic yam ntxwv, tus ntoo khaub lig ntawm lub raj yog qhov zoo tshaj plaws, thiab cov nyhuv ntawm cov cua thiab dej ntws tau txo qis heev. Cov ntu ntu ntawm lub raj plaub yog zoo ib yam li lwm qhov qhib seem hauv qhov no.
3. Cov yeeb nkab steel yog ib feem kaw; Thaum qhov nruab nrab thickness thiab cross-sectional cheeb tsam yog tib yam, qhov chaw ntawm qhov chaw raug yog li ntawm 50% mus rau 60% ntawm qhov qhib seem, uas yog qhov zoo rau corrosion corrosion thiab txuag cov ntaub ntawv txheej.
4. Qhov kev sib txuas ntawm node yog tsim rau kev sib txuas ncaj qha, tab sis nws tsis dhau ntawm cov node board lossis lwm cov khoom sib txuas, uas yog ob qho tib si ua haujlwm-txuag thiab cov khoom xyaw.
5. Cov duab zoo nkauj dua, tshwj xeeb tshaj yog lub raj truss muaj li ntawm cov yeeb nkab steel. Tsis muaj qhov sib txuas ntau dhau thiab muaj kev nkag siab zoo ntawm kev niaj hnub.
6. Yog tias tsim nyog, pob zeb tseem tuaj yeem muab nchuav rau hauv lub raj los tsim cov khoom sib xyaw ua ke.
Vim qhov zoo li saum toj no, cov qauv steel yeeb nkab muaj cov qauv ntawm li 20% ntawm cov hlau hauv cov tsev lag luam piv nrog cov qauv tsim los ntawm qhov qhib seem, thiab cov nyiaj txuag tuaj yeem ncav cuag 50% hauv cov qauv ntauwd. Cov qauv steel yeeb nkab tuaj yeem siv cov qauv raj raj lossis lub raj lub voj voog raws li lub siab ntawm cov khoom siv, cov khoom siv, kev tsim khoom thiab kev ua haujlwm, thiab tus nqi, thiab tuaj yeem sib xyaw nrog ob lub yeeb nkab steel. Thaum sib tov, txoj hlua hlua feem ntau yog lub raj raj, thiab lub plab mog yog siv rau hauv ib lub raj puag ncig; Qee zaum, txoj hlua hlua kuj tuaj yeem siv rau hauv ib lub raj raj lossis ib lub raj puag ncig rau lub plab pas nrig.
Thaum lub sij hawm kho tshuab kev ua tau zoo, qhov kev ruaj ntseg yog qhov zoo tshaj plaws los ua rau hauv zos flexion thaum nws yog compressed. Hluav taws kub tsis kam thiab cov khoom siv tiv thaiv corrosion yog qhov kev cawmdim tshaj plaws.
