Conical Roof Calculations
Conical Roof Calculations
(OP)
I had modeled a conical roof and I checked the stresses with API 620. The results are way off. Can somebody highlight where I had gone wrong? I had attached RISA model with Hand calculation. The bottom dia is 12 ft and the top dia is 1 ft and the height is 1 ft. The Live load is 25 psf. The thickness of plate is 0.135 inches.





RE: Conical Roof Calculations
Currently in your Risa model, you only have the dead load included in your load combination.
