Ku bijyanye n'ubwubatsi n'ubwubatsi, imitako ya ASTM yagutse ni amahitamo akunzwe cyane ku mishinga myinshi. Iyi mitako, izwi kandi nka W beams cyangwaImirasire y'igice cya H, ni ibintu by'ingenzi mu gukora inyubako zikomeye kandi zizewe. Muri iyi blog, tuzareba ibyiza n'imikoreshereze y'imitako ya ASTM, n'uburyo igira uruhare runini mu nganda z'ubwubatsi.
Imitako y'urukiramende rwagutse ya ASTM niimitako y'icyuma gishyushye cya Hzikoreshwa cyane mu kubaka inyubako, ibiraro, n'izindi nyubako. Imiterere yazo ituma habaho igipimo cyo hejuru cy'imbaraga hagati y'uburemere, bigatuma ziba nziza cyane mu gutwara imizigo iremereye mu gihe kirekire. Imiterere y'iyi miyoboro isa n'inyuguti "H," ifite uduce two hejuru no hepfo dutanga imbaraga n'ubudahangarwa bihebuje.
Kimwe mu byiza by'ingenzi by'imitako ya ASTM ni uburyo ikoreshwa mu buryo butandukanye. Iyi mitako iza mu bunini n'ingano bitandukanye, bigatuma ikoreshwa mu buryo butandukanye. Yaba iyo kubaka amazu, ubucuruzi, cyangwa inganda, iyi mitako ishobora guhindurwa kugira ngo ihuze n'ibisabwa by'umushinga uwo ari wo wose. Byongeye kandi, kuba ihuriweho kandi ikanamenyekana mu mikorere bituma iba amahitamo yizewe kuriicyuma cy'ubwubatsi H umurabyoporogaramu.
Imirongo y'imirasire ya H, indi mikoreshereze yaimitako ya ASTM yagutse, zikunze gukoreshwa mu kubaka urufatiro. Zijugunywa mu butaka kugira ngo zishyigikire inyubako, ibiraro, n'izindi nyubako. Ubushobozi bwazo bwo kwihanganira imitwaro iremereye no kwirinda kunama no guhindagurika bituma ziba amahitamo meza yo gukora urufatiro.
Imitako y'icyuma gishyushye ya H nayo ikoreshwa cyane mu gukora inyubako z'icyuma. Ingufu zayo zidasanzwe no kuramba kwazo bituma ziba amahitamo meza yo gukora inyubako zikomeye kandi zizewe ku nyubako n'izindi nyubako. Byaba ari ububiko bw'inganda, inyubako z'ubucuruzi, cyangwa amazu yo guturamo, iyi mitako ni ingenzi mu kwemeza ko umushinga uhamye.
Mu gusoza, imitako y'urukiramende rwa ASTM igira uruhare runini mu nganda z'ubwubatsi. Kuba ifite ubushobozi bwo gukora ibintu byinshi, imbaraga, no kwizerwa bituma iba ingenzi cyane mu gukora inyubako zikomeye kandi zirambye. Byaba ari ugushyigikira imitwaro iremereye, gutanga inkunga y'ishingiro, cyangwa gukora inkingi z'icyuma, iyi mitako ni ingenzi mu gutuma imishinga y'ubwubatsi igenda neza kandi itekanye. Ku byo ukeneye byose ku nyubako z'icyuma cya H, imitako y'urukiramende rwa ASTM ni amahitamo meza cyane.
