Can CAESAR II calculate thin-walled air ducts with rectangular cross-sections?
Thread Content
I’d like to ask everyone: can CAESAR II calculate thin-walled air ducts with a rectangular cross-section?
No. Mainly, the standards don’t support it either.
Of course not. For rectangular smoke and air ducts, special methods are required for both local stress analysis and overall structural analysis. The calculation of local stresses can be simplified to some extent; domestic standards such as DL/T5121 exist, but these standards do not address how to account for local stresses at the locations of supports and hangers； The main difficulty in the overall calculation lies in the large number of external loads, factors such as wind load and seismic effects, as well as the combinations of operating conditions. Furthermore, the stability of thin-walled structures is also an important aspect in the calculations.
