Intshayelelo yemveliso
Ibhulorho yetruss kaloliwe ibhekisa kwibhulorho enetruss njengeyona nxalenye iphambili yokuthwala umthwalo we superstructure.Ibhulorho yetruss ngokuqhelekileyo yenziwe ngesakhelo sebhulorho engundoqo, iisistim zoqhagamshelo eziphezulu nezisezantsi ezithe tyaba kunye nezinde, isakhelo se-portal yebhulorho kunye ne-intermediate brace, kunye nenkqubo yedekhi yebhulorho.
Isicelo semveliso
Ngokuqhelekileyo isetyenziselwa iibhulorho zikaloliwe okanye ii-viaducts zikaloliwe kunye neepaseji ezinobubanzi obuncinci.
Ulwakhiwo lweMveliso
1. Ibhulorho yeTruss luhlobo lwebhulorho.
2. Iibhulorho zeTruss ziqhele ukubonwa koololiwe kunye neendlela ezikhawulezayo;Yahlulwe yaba ziindidi ezimbini zamandla echord aphezulu kunye ne-low chord force.
3. I-truss yenziwe nge-chord ephezulu, i-chord ephantsi kunye nentonga yesisu;Ifomu yentonga yesisu ihlulwe ibe yintonga ye-oblique yesisu, intonga yesisu esithe ngqo;Ngenxa yobude obuncinane kunye nokubhitya kwentonga ngokwayo, nangona uxhulumaniso phakathi kweentonga lunokuthi "lulungiswe", umzuzu wokugoba wokwenene wentonga uncinci kakhulu, ngoko uyilo kunye nohlalutyo lunokwenziwa lula njenge "hinged".
I-4.Kwi-truss, i-chord ngamalungu enza i-periphery ye-truss, kuquka i-chord ephezulu kunye ne-chord ephantsi.Amalungu adibanisa iichords eziphezulu nezisezantsi zibizwa ngokuba ngamalungu ewebhu.Ngokweendlela ezahlukeneyo zamalungu ewebhu, zihlulwe zibe ziintonga ze-diagonal kunye neentonga ezithe nkqo.
Inqwelomoya apho iichords kunye neeweb zikhoyo ibizwa ngokuba yinqwelomoya engundoqo.Ukuphakama kwebhulorho yebhulorho ebanzi-ebanzi iyatshintsha ecaleni kwendlela yokwenza i-truss yentambo egobileyo;i-spans medium and small span zisebenzisa i-truss height engaguqukiyo, ebizwa ngokuba yi-flat string truss okanye i-strat truss.Isakhiwo se-truss sinokuqulunqwa sibe yintsimbi okanye ibhuloho ye-arch, kwaye ingasetyenziselwa njengentsimbi eyintloko (okanye i-stiffening beam) kwibhulorho yenkxaso yentambo.Uninzi lweebhulorho zetruss zenziwe ngentsimbi.Ibhulorho ye-truss yisakhiwo esingenanto, ngoko ke inokulungelelaniswa kakuhle kwidekhi ephindwe kabini.
