Analysis and Design of RC Spherical Dome Structure

Abstract

A dome can be described as a thin shell
created by a regular curve rising around one
of its axes. The type of the bow and the path
of the axis of revolution strongly influence the
dome’s shape. Huge storied skyscraper is
wrapped in a twisted roof. When the interior
of the structure is open and lacks walls or
pillars, the shell roof is useful. D0mes are
employed in a variety of constructions,
including auditoriums, exhibition halls, round
tanks, and the roofs of spherical regions.
D0mes can be built out of RC concrete, steel,
wood, masonry, and other materials. Here,
STAAD-PRO software is used for analysis as
well as manual design of the RCC dome roof
structure, providing detail design of RCC
domes. It was clearly demonstrated how to
create RCC domes, and from the design we
can obtain the ring beam reinforcement,
dome’s hoop reinforcement, and meridian
reinforcement. STAAD study of monolithic
dome structures is another component of this
research. In this revision, point loads are
being applied across the nodal joints, and
STAAD will be used to develop the analysis
and design of the concrete dome structure.
Four models are analysed using the
equivalent static approach and various plate
thicknesses in STAAD. Medium seismic zone
and medium soil type are used in the analysis.
Nodal displacement, axial force, shear force,
bending moment, and maximum absolute
plate stress are obtained as a result of the
analysis.
