Kupititsa patsogolo Mapaipi Azitsulo Zosapanga dzimbiri

Chitsulo chilichonse chomwe chimatseguka pamapeto onse awiri ndipo chimakhala ndi gawo lopanda kanthu, ndipo kutalika kwake kuli kwakukulu kuposa gawo la gawolo, kungatchedwe chitoliro chachitsulo. Pamene kutalika kuli kochepa kusiyana ndi gawo la gawolo, likhoza kutchedwa gawo la chitoliro kapena chitoliro choyenera. Onse ali m'gulu la mankhwala chitoliro.

Kwa zaka zoposa makumi asanu ndi limodzi, akatswiri a zomangamanga asankha zitsulo zosapanga dzimbiri kuti amange nyumba zokhazikika zotsika mtengo. Nyumba zambiri zomwe zilipo zikuwonetseratu kulondola kwa chisankho ichi. Zina ndi zokongola kwambiri, monga Chrysler Building ku New York City. Koma muzinthu zina zambiri, ntchito ya chitsulo chosapanga dzimbiri ndi yochepa kwambiri, koma imakhala ndi gawo lofunika kwambiri pakukongoletsa ndi ntchito za nyumba. Mwachitsanzo, chifukwa zitsulo zosapanga dzimbiri zimagonjetsedwa ndi abrasion ndi indentation kusiyana ndi zitsulo zina za makulidwe ofanana, ndizomwe zimasankhidwa kwa okonza pomanga misewu m'madera omwe anthu ambiri akuyenda.

Zitsulo zosapanga dzimbiri zakhala zikugwiritsidwa ntchito ngati zida zomangira nyumba zatsopano komanso kukonzanso malo akale kwa zaka zopitilira 70. Mapangidwe oyambirira ankawerengedwa motsatira mfundo zoyambirira. Masiku ano, ma code opangira, monga American Society of Civil Engineers 'standard ANSI / ASCE-8-90 "Cold Formed Stainless Steel Structural Design Code" ndi NiDI ndi "Structural Stainless Steel Design Manual" ya Euro Inox apangitsa moyo wautali kukhala wosalira zambiri. Mapangidwe a zigawo zamapangidwe ndi kukhulupirika kwabwino.
