What is a dome
There are generally two interpretations of dome
dome overhanging hemispherical space or area
crown, vault the apex or top of a dome or a dome
surface (such as a street or bridge facing the
central arch), especially a road with a round
arch The difference in height between the center
and its edges.

Classification of domes

• 1. Beamless shell type
• 2. Beam plate type
• 3. Space frame type

Beamless shell dome
The steel beamless shell dome is a beamless steel
plate shell structure. The shell is a
self-supporting system, and every point of the
shell bears tensile and compressive stress and
shear stress, without the effect of bending
distance.

Dome of Chengguan Mosque in Xunhua, Qinghai
The beamless shell dome is a shell formed by
cutting steel plates and pressing them into
corresponding hyperboloids, which are assembled
and welded. The wall thickness of the steel shell
is determined according to the size of the dome
and the load situation.

Dome of Todai Mosque in Tianjin
Various decorative accessories on the beamless
shell dome are directly fixed on the shell
structure. The dome of the mosque is a typical
beamless shell dome structure?

Beam-slab dome
The beam-slab dome consists of several vertical
curved beams as the force-bearing members. The
lower ends of the curved beams are fixed to the
ring beams or roof slabs of the building at an
equal distance the upper ends meet and are fixed
to the iron ring beams or nodes in the center of
the main roof. On the board.

Beam-slab dome
The beam-plate dome panel is made of steel
corrugated plate, single-curved arc plate,
hyperbolic spherical plate or trapezoidal
stainless steel plate, titanium alloy plate,
aluminum plate, steel plate, color steel plate,
PC endurance plate, glass steel plate or glass
plate, etc. of.
10
Space frame dome
The space frame dome uses a spherical space frame
as the main structural system, and the outside of
the space frame is covered with plates or glass
according to different needs.
11
Space frame dome
The glass dome can meet the lighting needs of the
building. Natural light is filtered into the
environment through the glass interface, making
the building visually light and transparent.
12
Features of the dome structure
Beamless shell mosque domes generally use 3-4 mm
thick q235b steel plates, pressed into
hyperboloid tiles, and 6 mm thick steel plates as
stiffeners. The tiles are tightened with bolts,
and the joints are fully welded by electric
welding. The cost of this structure is relatively
low.
13
Features of the dome structure
The two adjacent curved beams of the beam-slab
dome are connected by horizontal ribs when
necessary, and the panels of the dome are fixed
on every two adjacent curved beams and ribs. The
auxiliary roof is fixed on the upper part of the
central ring beam or curved beam of the main
roof. The surface of the structure is covered
with hyperboloid sheet or glass as required. The
cost of hyperboloid glass is relatively high.
14
Features of the dome structure
The space frame dome uses a bolted ball grid as
the main structure, and the covering material can
be divided into blocks according to the size of
the grid. Compared with the hyperboloid molding
material, the cost is lower.
