Net Frame, Heterosexual Structure Class

Zida zoyambira m'gululi ndizakona zazing'ono, matenthedwe atatu, kiyubiki, kanyumba kakang'ono kotere ndi zina zotero. Zinthu izi zimatha kuphatikizidwa kuti apange utatu, mbali zinayi, zozungulira, zozungulira, kapena mtundu wina uliwonse wamapulani. Ubwino wa mphamvu yamlengalenga, kulemera pang'ono, kuuma kwakukulu, magwiridwe antchito azisangalalo, etc. Itha kugwiritsidwa ntchito ngati denga la malo ochitira masewera olimbitsa thupi, bwalo lamasewera, holo yowonetserako, holo yodikirira, bwaloli loyimilira, hangar ya ndege, mbali ziwiri zazikulu ndi malo ogwirira ntchito ndi nyumba zina.

Gulu la gridi:

Kalasi yoyamba ili ndi makina oyendetsa ndege, omwe amaphatikizira mitundu inayi, yomwe ndi njira ziwiri zoyendetsera kolowera, mbali ziwiri zoyendetsera grid, mbali ziwiri zowonekera poyikapo gridi ndi mbali zitatu zokonda kuyika gridi.

Mtundu wachiwiri umapangidwa ndi ma quadrilateral pyramidal unit. Pali mitundu isanu: grid yoyenda bwino ya quadrilateral, grid yoyenda bwino ya quadrilateral, gridi ya oblique quadrilateral, grid ya checkerboard quadrilateral ndi grid ya star quadrilateral.

Mtundu wachitatu umapangidwa ndi mayunitsi amphona atatu a piramidi. Pali mitundu itatu yamaukonde amtundu wa pyramidal, maukonde opangira ma tricone ndi maukonde a tricone. Malingana ndi mawonekedwe a zipolopolo, zipolopolo zimatha kugawidwa kukhala chipolopolo cha cylindrical, ozungulira chipolopolo ndi chipolopolo cha hyperbolic parabolic. , pali gridi yazitsulo, grid ya konkriti yolimbitsa ndi chitsulo komanso grid yolimbikitsidwa ya konkriti, yomwe grid yazitsulo imagwiritsidwa ntchito kwambiri.

Kufufuza kwa mkati mwa gridi:

Kapangidwe ka gridi ndiyotsogola kwambiri pakapangidwe kake kosiyanasiyana.Kuwunika kwa truss yamtundu wa mbale, nthawi zambiri kumaganiziridwa kuti malumikizowo adalumikizidwa, ndipo katundu wakunja umachitidwa ndi zimfundo molingana ndi mfundo yomweyi, yomwe ingakhale Kuwerengedwa molingana ndi njira yosamutsira malo, yomwe ndi njira yochepetsera njira yolumikizira ndodo. Njira zowerengera zosavuta, monga njira yopingasa njira yosinthira mbale ndi mbale - ngati njira, itha kugwiritsidwanso ntchito kuwerengera magulu amkati ndi osamuka. ya gulu limodzi lokhala ndi ziboliboli nthawi zambiri limaganiziridwa kuti ndilophatikizika, lomwe limayenera kuwerengedwa molingana ndi njira yocheperako yolumikizira yolumikizira. -shell njira itha kugwiritsidwanso ntchito kupeputsa kuwerengera kwa magalasi osanjikiza ndi awiri osanjikiza.

Design kapangidwe gululi:

Gawo la mtanda wa truss liyenera kutsimikiziridwa molingana ndi kuwerengera kwamphamvu ndi kukhazikika. Kuti muchepetse kutalika kwa bala lazitsulo ndikuwonjezera kukhazikika kwake, njira monga kuwonjezera kukonzanso bar ndikuthandizira bala zitha kutengedwa. ya gridi yamtundu wa mbale ndi grid ya chipolopolo chopangidwa ndi chitsulo makamaka imaphatikizapo mitundu itatu: chophatikizira cha mtanda, cholumikizira chophatikizira cha mpira ndi cholumikizira. Ndodo yolumikizira ndi yolumikizira yolumikizidwa ndi kuwotcherera kapena ma bolts amphamvu kwambiri. Malo olumikizira mpira ndi bolt yolumikizira mipira ndioyenera kapangidwe kazitsulo kazitsulo kazitsulo. mphamvu zamkati. Mwambiri, kugwiritsidwa ntchito kwazitsulo kwamafundo kumakhala pafupifupi 15 ~ 20% yazitsulo zomwe zimagwiritsidwa ntchito pakupanga gululi ....
