Re: Brick Dome Design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If you design as a two wythe cavity structure with grout and reinforcement
it should be a pretty straight forward design, you can find dome design
guidelines in a number of different text references (Horizontal Span
Building Structures, by Schueller as an example).  Provide a continuous
support / anchorage ring around the base and let the dome be self
supporting.  With a secondary roof over the dome the design loads should be
easy to manage.  What is the supporting structure? Steel framed this would
be a slam dunk.

With a concrete support structure you could design the brick as a wire tied
veneer system tied to a shotcrete reinforced dome backing so to speak.
Again the dome itself is inherently stable, with a proper cast tie /
anchorage ring adjoining the primary structure it should not be too
difficult.

I would not want to support the dome on a wood framed system.  If the
structure is wood I would provide an independent steel frame system to
support the dome.  Masonry domes are very efficient, the biggest enemy of
the system would be differential settlement of the supports.
