H Beam marka ayan Qoraxda | Beams steel ee dhammaan ah ee ku jirin flexural strength

Qolobada H waxaa lagu yeeray kartaa si toos ah ee dhexeeminta jajabka badbaadaha, oo ku yimid qofka ugu dambeeya ee kudiibka carruurta iyo xirfadda caafimaadka. Qolobada badbaadaha ka mid ah ayaa ku yimid standaradii kama AASHTO ee Northern America ama EN 10025 ee Erop, macluuma ah ee gradyada A572 Grade 50 iyo S355J2 . "H" shaqooyinkaas wuxuu ku xoogaya momentyada carruurta ah, ku yaal in lagu soo galitaan deflection la xiriira traffic carruurta. Xusuusashooyinka design ayaa ku yimid length carruurta (carruur shimbir ah ayaa ka dib marka lagu talagalay sections lacag ah 200x100mm, markii aad ugu sameeyo carruur kuwasaar ah ayaa loo baahnaa beams 630x178mm), exposure joogga (coatings galvanized leh badbaadaha dhulka), iyo seismic activity (grades ductile leh earthquake zones). Fabricationna waxaa lagu sameeyaa cambering leh ku saabsan sagging la xiriira loads carruurta ah, shop welding leh ayaa preferred leh precision. Connection detailsna waa critical—moment resisting joints ayaa ku yimid fully welded flanges, simple supportsna ayaa ka dib marka lagu talagalay bolted web connections. Shacabaha kale ayaa ku yimid high performance steel (HPS) grades leh oo ayaa ku haysta weights qolobada carruurta ah 20% markii aad ugu sameeyo strength, iyo alloys korista ah leh longevitiy ee harsh environments. Maintenance considerations, macaamiisha coating inspection accessible ah, ayaa ka sameeyeen design.
