Dear anyone,
I am designing a dome with radius 40'. I have designed it manually (i.e amount of meridian and hoop stresses ) but since the dimension is very large, i have difficulty in designing the circular beam under dome (their occurs very large bending moment). i had searched the forum but every attachment has been either removed or is no longer available. now i am trying to model and design it in Etabs. and i read the material on forum the method using extrude properties command, but what properties should be assigned and what results should i be looking for?
