Kugwiritsa ntchito mankhwala
Nthawi zambiri amagwiritsidwa ntchito ngati milatho yapamsewu yokhala ndi milatho yaying'ono.
Kapangidwe kazinthu
Mucikozyanyo, cibeela eeci ncitondezyo cazikombelo zyobilo, kubikkilizya aciimo camujulu naa cikozyanyo cibotu. Mamembala omwe amalumikiza ma chords apamwamba ndi apansi amatchedwa mamembala a intaneti. Malingana ndi mayendedwe osiyanasiyana a mamembala a pa intaneti, amagawidwa kukhala ndodo za diagonal ndi ndodo zowongoka.
Ndege yomwe ma chords ndi maukonde amapezeka amatchedwa main girder plane. Kutalika kwa mlatho wa mlatho waukulu wa span kumasintha motsatira njira ya span kuti apange chingwe chopindika; zing'onozing'ono zapakatikati ndi zazing'ono zimagwiritsa ntchito kutalika kwa truss kosalekeza, zomwe zimatchedwa truss lathyathyathya kapena chingwe chowongoka. Mapangidwe a truss amatha kupangidwa kukhala mtengo kapena mlatho wa arch, ndipo angagwiritsidwenso ntchito ngati mtengo waukulu (kapena chitsulo chowumitsa) mu mlatho wothandizira chingwe. Milatho yambiri ya truss imapangidwa ndi chitsulo. Mlatho wa truss ndi wosanjikiza, kotero umatha kusinthika bwino pamasitima apawiri.
Ubwino wa mankhwala
Steel truss mlatho umaphatikiza zabwino zamapangidwe achitsulo ndi truss:
1. Kuwala kwapangidwe ndi luso lalikulu lotambasula
2. Zosavuta kukonza ndikusintha
3. Mtsinje wachitsulo uli ndi mamembala ambiri ndi mfundo, kapangidwe kake ndi kovuta kwambiri, ndipo kukhazikika kumakhala kolimba.
4.Kutsutsa mwamphamvu kukakamizidwa ndi kukhulupirika kwabwino
5. Ntchito zambiri
