CHS (Circular Steel Frames) yog seamless los yog welded steel hlab nrog ib ncig -section. Lawv feem ntau siv nyob rau hauv truss systems, qhov chaw thav duab, thiab offshore qauv vim lawv zoo heev torsional tsis kam thiab uniform zog nyob rau hauv tag nrho cov lus qhia.
SHS (Structural Steel Frames) zoo ib yam li RHS (Circular Steel Frames), tab sis nrog tus ntoo khaub lig -section. Lawv feem ntau siv nyob rau hauv cov qauv thav duab, truss systems, thiab kev txhawb nqa txhua, muab cov khoom zoo heev -cov kabmob muaj peev xwm thiab yooj yim ntawm kev tsim khoom.
SHS VS CHS Tube
| Feature | SHS (Square Hollow Section) | CHS (Circular Hollow Section) |
|---|---|---|
| Hla -sectional shape | Square (tag nrho cov sab sib npaug) | Circular (uniform radius) |
| Khoov kev ua tau zoo | Isotropic (lub zog sib npaug ntawm txhua qhov kev qhia) Yooj yim rau kev ntxhov siab concentration ntawm cov ces kaum |
Uniform dabtsi yog khoov (tsis muaj kev ntxhov siab concentration ntsiab lus) Siab torsional kuj |
| Compressive kev ua tau zoo | Zoo (tsim rau axial loads) | Zoo heev (symmetric seem, npaum load faib) |
| Kev sib txuas yooj yim | Siab (yooj yim rau ntsia liaj qhov rooj lossis vuam ntawm qhov chaw tiaj tus, yooj yim sib dhos) | Nruab nrab- qis (yuav tsum tau flanges los yog welded rings, complex directional kev twb kev txuas) |
| Cov qauv kev tsim khoom siv | ASTM A500, EN 10219, JIS G3466 | ASTM A500, EN 10219, JIS G3466 |
| Tej kev siv | Lub tsev ncej kab teeb, kev sib koom ua ke, tshuab hauv paus | Load-cov kabmob, cov kav dej, cov hlab ntsha siab, kev txhawb nqa choj |
