Flat dome construction
I am a student at the university of Bath doing my Msc in historic building conservation. I have been working on various conservation projects in India and have come across vaults which have a sort of flat dome construction - the attached photographs are from the ceilings of Ramgarhia Bunga in Amritsar.

I was wondering if anyone could suggest some books on the construction and behavior of flat domes. Also, as I am quite fascinated by the flat dome construction in India, I am keen to find out more about this kind of construction elsewhere in the world -- especially in the Islamic world. Do you think I could get enough material on the evolution, construction and structural behavior of flat vaults for my dissertation?

Hope you can direct me and help me find something with which i can begin my research.

Hi Ajaydeep,

You could check out the bibliography of this book called Towers and Domes by Felix Escrig. I think he is Spanish and there is a possibility that you will find this kind of flat-dome vault construction in some buildings in Spain. Will let you know the names of the buildings if I can find out.

Dear Derek, thanks for your response.

I did look up the book you suggested. It has good textural and graphic essays about the general evolution and symbolism of the dome, however there is nothing about the flat dome construction. Maybe I should look for this kind of construction under vaults and not domes.

Any more suggestions would be welcome and I hope someone can provide me with pictures or names of places where they have seen this kind of construction.

Thanks,

Hello,

Here in Dpain there is a quite famous flat dome in an incredible building, El Escoriar near Madrid. There's a flat dome at the entrance of the basilica.

Try googling Cupula Plana or Boveda Plana or Escorial.

Hi Ajay,

I know it's quite late but since Jose re-opened the discussion, I wish to contribute my part.

Though you may know of it from Paromita, shallow or flat domes in Delhi were first constructed extensively during the Tughlaq period in the 14th century. Several buildings erected during Feroz Shah Tughlaq's reign, such as Khirki Masjid, incorporated these. The construction comprises of Delhi quartzite masonry with lime mortar, and the span around three meters. What is interesting is the supporting system devised for the roof that combines single, double and four-shafted pillars.

Hope to have helped. I did send a few images long time back, apparently you never got them. Here are some of them. Tell me if you need any more.

All the best,

Another image. Notice the break between the commonly singular curve of the pendentive that continues into the dome.

The pillars.

Since the roofing at Khirki is a combination of shallow and deep domes, different pillars are provided to combat thrusts from these domes.
