what are the assumptions in designing a Dome of Masjid? how i can design it using SAP? Dimensions: radius 21', hieght 10'

How can we analyze the dome with point load at the apex by classical shell theories or approximate theories??? -
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?

Posting this thread to break the ice. Modelling domes is very easy in Etabs/SAP. All you need to do is to draw the curvature of the dome in elevation by a series of straight lines, but draw only the one half. Then using the apex at centre point, radially extrude the line say 24 times at 15 degree intervals (or 48 times at 7.5 deg intervals. This feature is under Edit> Extrude Lines to areas. You can further use this geometry for Finite Element Analaysis.

is dome analysis and design a difficult task ??? http://www.sepakistan.com/public/style_emoticons/#EMO_DIR#/mellow.png someone said that it comes under the category of FEM and that FEM thing is too cumbersome that it may take three months to complete the whole process http://www.sepakistan.com/public/style_emoticons/#EMO_DIR#/rolleyes.gif

Pantheon is a building in Rome built at about 126 AD. It has world's largest un- reinforced concrete dome in the world. I am amazed to know that Romans were able to built a dome of such scale without any reinforcement , a feat that few will dare to attempt now. It has a diameter and height equal to 142 ft(43m). This building is in continuous use since 7 century.

Pier Luigi Nervi (June 21, 1891 – January 9, 1979) was an Italian engineer. He studied at the University of Bologna and qualified in 1913. Dr. Nervi taught as a professor of engineering at Rome University from 1946-61. He is widely known as a structural engineer and an architect, and for his innovative use of reinforced concrete. Attached is the pic from on his structures. Roof of multipurpose hall,material is RCC.
