I have difficulties understanding technical matters regarding a self supported (no middle columns) roof for an API water tank.
1. The excel sheet on the right shows 6mm thickness for the roof. I assume it is because no rafter are being used, otherwise thickness would be around 2mm. Am I right?
2. On the photo on the right, the rafters appear to resting on some rod extending to the bottom. Is it something similar to 2cm x 2cm square hollow section? Or am I erroneously understanding the image?
Regards
