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.

Saying results are way off doesn't describe what results you are talking about.

Currently in your Risa model, you only have the dead load included in your load combination.
