1. Recently I am trying to model a 80ft Concrete Stack. The model generator has a template but not to my use even i try to edit it. The geometry is a little complex for me. It has a bottom dia of 30 ft changing into bottle neck at a distance of 33 ft the dia is 15 ft. this remains constant upto the ht of 60 ft then again the dia of chimney increase to 22 ft. Now i am puzzeled how to model this...
2. Previously i designed a concrete building and a steel strucutre seperatrely. the strucure was to be errected on top of the building so i used the support reaction of the steel structure and assigned them at the connection points but the client insitted that i place the steel structure on top of the concrete building and run the combine analysis and design. When i imported the steel model to concrete all section properties, loads every thing is assigned were gone .... I had to do everything again.... MY QUESTION IS :
Is there any way to import without losing these things?
Staad do not design concrete and steel combined.. so i designed both of them seperately.... IS it OK?
