¤ As in the picture, the roof and beams will be wooden, so how can I calculate the load on the columns? ¤ I can't pass the 11 meter spans requested from me in the attached project. I made cassette slabs, I made slab slabs, I changed the dimensions of the columns, but I get a column-beam junction error. How else can I design the gallery space? I'm a new graduate, be exposed. I need your information.
