Kupanga mizati yachitsulo ndi zothandizira
1. Ndondomeko ya mapangidwe a chimango
Chigawo chamzere mawonekedwe: bokosi mawonekedwe, welded I-mawonekedwe, H-mawonekedwe zitsulo, chitoliro chozungulira, etc
Chiyerekezo cha gawo: Malinga ndi mamembala a 1.2N axial compression, 3 ~ 4 zigawo za kusintha kwa gawo, makulidwe sayenera kupitirira 100mm
M'lifupi mwake ndi makulidwe a mbale, onani tebulo pansipa
Slenderness ratio: Mipikisano wosanjikiza (£ 12 wosanjikiza) chimango ndime sikuyenera kukhala wamkulu kuposa 120 pamene 6 mpaka 8 madigiri chitetezo, ndipo sikuyenera kukhala wamkulu kuposa 100 pamene 9 madigiri chitetezo.Pamene mphamvu ya mpanda ndi 6,7, 8 ndi 9 madigiri, kutalika kwa mzere wautali (> nkhani 12) ndi 120, 80 ndi 60, motero.
The "Technical Regulations for Steel Structures in high-rise Civil Buildings" (JGJ99-98) imati: powerengera kukhazikika pansi pa kuphatikiza mphamvu yokoka ndi mphepo kapena zivomezi, ngati mtengo wapakati-wosamuka sudutsa 1. / 250 ya kutalika kwa ndime ya chimango, kutalika kowerengeka kwa gawo la chimango ndi chithandizo (kapena kumeta khoma) kungakhale m=1.0;Ngati mulingo wokhazikika wakusamuka kwanyumba sikudutsa 1/1000 yautali, chiŵerengero chautali chowerengeredwa cha chigawo choyera cha chimango chingathenso kuwerengedwa ndi njira ya Wu's lateral displacement formula.
GB50017 ya chimango chothandizira imagawidwa mu chimango cholimba chothandizira ndi chimango chothandizira chofooka.
2, kugwirizana kwa mzere ndi mtanda
★ Common mawonekedwe: kugwirizana okhwima
★ welded kwathunthu
★ Wotsekedwa kwathunthu
★ Kusakaniza kowotcherera bolt
★ Mawonekedwe okokedwa bwino: fupa lolumikizana (fupa la galu), kumapeto kwa mtengo wokhala ndi ma axils, gawo la mtengo wa cantilever
★ Fomu yolumikizira yosinthika: kulumikiza Angle chitsulo, mbale yomaliza, chithandizo
★ Kulumikizana kolimba: mbale yomaliza - njira yolumikizira bawuti yamphamvu kwambiri, chitsulo chapamwamba ndi chotsika cha Angle ndi mawonekedwe a bawuti amphamvu kwambiri
