Ibikoresho byubaka Digital (DBC), uruganda rukora ibyuma bikonje (CFS) rukora umushinga wa Mayo West Tower umushinga wa Phoenix, muri Arizona, rwahawe igihembo cya 2023 Cold Formed Steel Engineers Institute (CFSEI) igihembo cyiza cyo kuba indashyikirwa mubikorwa (Serivisi za Komini / Serivisi ”) . kubera uruhare rwe mu kwagura ifasi y'ibitaro. Igishushanyo mbonera cyibishushanyo mbonera.
Mayosita ni inyubako y'amagorofa arindwi ifite metero kare 13,006 (140.000 sq ft) ya CFS yakozwe mbere yimyenda yimyenda yimbere yimbere yagenewe kwagura gahunda yubuvuzi no kongera ubushobozi bwibitaro bihari. Imiterere yinyubako igizwe na beto kumurongo wibyuma, gushushanya ibyuma hamwe na CFS yabanje gutunganyirizwa hanze idafite imizigo.
Kuri uyu mushinga, Pangolin Structural yakoranye na DBC nka injeniyeri wabigize umwuga CFS. DBC yakoze ibyuma bigera ku 1.500 byateguwe mbere ifite idirishya ryashyizweho mbere, hafi metero 7.3 z'uburebure na metero 4,6 z'uburebure.
Ikintu kimwe kigaragara cya Mayota nubunini bwibibaho. Mm 610 mm (24 muri.) Uburebure bwurukuta rwumurambararo hamwe na mm 152 (6 muri. . . Mu gutangira umushinga, itsinda ryabashushanyaga DBC ryashakaga gushakisha uburyo butandukanye bwo gukora mm 610 (24 in) z'ubugari, 7.3 m (24 ft) z'uburebure bwateganijwe mbere. Itsinda ryiyemeje gukoresha mm 305 (santimetero 12) kurwego rwa mbere rwurukuta, hanyuma rushyira J-beam itambitse kuri urwo rwego kugirango itange inkunga yo gutwara neza no kuzamura ibyo birebire birebire.
Kugira ngo ikibazo gikemuke cyo kuva ku rukuta rwa mm 610 (24 muri.) Ujya kuri mm 152 (6 muri.) Urukuta rwahagaritswe, DBC na Pangolin bahimbye imbaho nkibice bitandukanye hanyuma barazisudira hamwe kugirango bazamure nkigice kimwe.
Byongeye kandi, imbaho zurukuta imbere zifungura idirishya zasimbujwe mm 610 mm (24 in) zometseho urukuta rwa mm 102 (4 in). Kugira ngo iki kibazo gikemuke, DBC na Pangolin bongereye umurongo muri mm 305 (12 in) hanyuma bongeraho 64 mm (2,5 in) sitidiyo kugirango yuzuze neza. Ubu buryo buzigama ibiciro byabakiriya mugabanya diameter ya sitidiyo kuri mm 64 (2.5 muri.).
Ikindi kintu cyihariye kiranga Mayosita ni sipi ihanamye, igerwaho hiyongereyeho mm 64 (2,5 muri.) Isahani yagoramye hamwe na sitidiyo kuri mm 305 gakondo (12 muri.).
Bimwe mubibaho byurukuta muri uyu mushinga byakozwe bidasanzwe na "L" na "Z" ku mfuruka. Kurugero, urukuta rufite uburebure bwa metero 30 (30 f) ariko ubugari bwa metero 1.8 gusa, hamwe na "L" inguni zingana na 0.9 m (3 ft) uhereye kumwanya munini. Kugirango ushimangire isano iri hagati yingenzi na sub-paneli, DBC na Pangolin koresha udusanduku twa pisine hamwe na CFS imishumi nka X-brace. Izi panne zifite L nazo zari zikeneye guhuzwa na batteri ifunganye ya mm 305 gusa (12 in) z'ubugari, ikaguka kuri metero 2 na 7 uvuye ku nyubako nkuru. Igisubizo kwari ugushira utwo tubaho mubice bibiri kugirango byoroshye kwishyiriraho.
Gushushanya parapeti byagaragaje ikindi kibazo kidasanzwe. Kugirango habeho kwaguka kwagutse kwibitaro, guhuza ibice byubatswe murukuta runini hanyuma bihindurizwa kumpande zo hasi kugirango byoroshye gusenywa.
Umwubatsi wiyandikishije kuri uyu mushinga ni HKS, Inc. naho injeniyeri yububatsi yanditswe ni PK Associates.
